methods of qualitative market research

Qualitative Market Research Methods + Examples

Qualitative market research is one of the most effective ways to understand consumer sentiment . If you really want to know how people feel about a product or business; and the ‘why’ behind it, qualitative research will tell you what you need to know.

This guide covers qualitative market research methods, including the different tools and techniques, their benefits, and examples of qualitative research in action.

What is qualitative market research?

Qualitative market research uncovers key insights into how people feel about a product or brand. It’s more of a touchy-feely type of market research than quantitative research , often performed with a small, handpicked group of respondents.

There are many different ways to conduct qualitative research. These include focus groups, interviews, ethnographic, observational research, and even biometrics. Although it takes time to conduct and analyze results, it’s one of the most popular types of market research .

Qualitative market research methods

Market research surveys are the most widely used qualitative market research method. Perhaps that’s down to their ease of use, availability, or the low cost of getting them out, in, and analyzed. But let’s be honest; all types of market research have pros and cons, which is exactly why picking the right technique is key.

Focus groups

What it is: Focus groups can be done in person or online. Participants are selected from within a target market or audience. Typically, people answer questions about the how, what, and why of a specific topic. While focus group formats vary, participant numbers should always be limited to ensure each person has the chance to contribute.

Best for: This type of qualitative market research is beneficial for testing new concepts or products in a market. It’s also good for getting feedback on existing products and things like usability, functionality, and ease of use.

Good to know: Online focus groups are becoming increasingly popular. As no interaction is required between participants, running them online allows responses to be collected in minutes without impacting data quality. It also reduces costs and means more people can attend due to fewer travel or time constraints.

What it is: Interviews are a tried-and-trusted qualitative research method that can be done in person or over the phone. It’s a highly personal approach that takes a conversational format between just two or three people. Researchers ask pre-set questions designed to collect intel and insights for further analysis. Interview formats vary depending on the research questions .

Best for Granular feedback from people within a target market or a target persona. Researchers obtain details about a person’s intentions, beliefs, motivations, and preferences.

What it is: Most people have used or consumed case study content in the past without necessarily realizing it’s a type of qualitative research. It analyzes contextual factors relevant to a specific problem or outcome in detail. Case study research can be carried out by marketing professionals or researchers and typically follows a structured approach, exploring a problem, the solution, and its impact.

Case studies can take anything from one month upwards to a year to develop and often involve using other types of qualitative market research, such as focus groups or interviews, to inform key content.

Best for: They’re more commonly used as a marketing tool to showcase a solution or service’s impact within a target market or use case. But, new product or service developments are two other popular applications.

What it is: One of the lesser-known methods of qualitative market research is biometrics. There’s an article about this on Bloomberg , showcasing how Expedia uses biometrics in its market research stack. The format for their project takes the trusty focus group scenario, adding a modern twist.

In this example, research participants were asked to attach a set of skin response sensors to their hands. But there could also be eye-tracking, emotional analysis, heat mapping, or facial sensors being used to track responses in tandem. Individuals were tasked with surfing the web; a researcher requested they do specific tasks or carry out a search in a self-directing manner. Responses are recorded, analyzed, and translated into meaningful insights.

Depending on the tech being used, the direction, and the goal of the research, this type of qualitative market research can show:

• How people surf the web or use a site
• The way people react in a specific situation
• How they respond to content, CTAs, layouts, promotions, tasks, or experiences
• Insights into what drives people to take action on a site

Best for: Larger digital-first companies with a budget to suit; those who want to perform UX testing to improve the content, customer journey, experience, or layout of a website.

Insightful The adoption of biometric technology in market research was at an all-time high in 2020. With the technology becoming more widely available, the adoption cost will likely fall, making it more accessible to a larger pool of organizations.

Ethnography

What it is: Enthnograprhic market research (EMR) is one of the costliest types of qualitative research. An experienced ethnographic researcher is needed to design and conduct the study. It analyzes people in their own environment, be it at home, an office, or another location of interest.

Research can take place over a few hours, months, or even years. It’s typically used during the early-stage development of a user-centric design project. But it can also be useful in identifying or analyzing issues arising once a product or service has gone to market.

Best for: It’s widely adopted within useability, service design, and user-focused fields. Getting under the skin of a design problem helps develop a deeper understanding of issues a product should solve. Outcomes help to build improvements or new features in products or services.

Grounded theory

What it is: Researchers use various qualitative market research methods, such as surveys or interviews, and combine them with other types of secondary market research to inform outcomes. Typically, participant groups are between 20-60, making it a larger sample size than focus groups. Responses are collated, and a series of specialist coding techniques are used to formulate a theory that explains behavioral patterns.

Best for: Organizations can better understand a target audience by using research to generate a theory. The findings provide explanations that can inform design decisions or spark new innovation through features or improvements to products or services. A typical use case could be when particularly heavy use of a product occurs or frustrations arise with usability – grounded theory is then used to explore the reasoning behind these behaviors.

Observational

What it is: Contrary to belief, this type of qualitative market research can occur remotely or on-site. A researcher will observe people via camera or being physically present in a shopping mall, store, or other location. Systematic data are collated using subjective methods that monitor how people react in a natural setting. Researchers usually remain out of sight to ensure they go undetected by the people they observe.

Best for: Low-budget market research projects. Suited to those with a physical store or who seek to examine consumer behavior in a public setting. Researchers can see how people react to products or how they navigate around a store. It can also provide insights into shopping behavior, and record the purchase experience.

Useful to know: Observational research provides more effective feedback than market research surveys. This is because instinctive reactions are more reflective of real-world behaviors.

Online Forums

What it is: A web message board or online forum is quick and easy to set up. Most people know how they work, and users’ names can be anonymized. This makes it a safe space to conduct group research and gain consensus or garner opinions on things like creative concepts, promotions, new features, or other topics of interest. The researcher moderates it to ensure discussions remain focused and the right questions are asked to thoroughly explore a topic.

Organizations typically invite between 10-30 participants, and forums are open for anything between 1-5 days. The researcher initiates various threads and may later divide people into subgroups once initial responses are given.

Here’s an example.

If a group of male participants indicates they dislike a specific content on the forum. The moderator would create a subgroup on the fly, with the intent of probing into the viewpoints of that group in more detail.

Best for: Discussing sensitive research topics that people may feel uncomfortable sharing in a group or interview. Getting feedback from people from a broad area and diverse backgrounds is easy. And a more cost-effective way to run focus groups with similar aims and outcomes.

What it is: For a survey to be considered a type of qualitative market research, questions should remain open and closed-ended. Surveys are typically sent digitally but can also be done in person or via direct mail. Feedback can be anonymous or with user details exposed. Surveys are a type of primary research and should be tailored to the research goals and the audience. Segmentation is a great way to uncover more about a select group of people that make up a target persona or market.

Best for: A low-cost way to question a large group of people and gain insights into how they feel about a topic or product. It can be used to flesh out usability issues, explore the viability of new features, or better understand a target audience in almost any sector. Surveys can also be used to explore UX or employee experience in greater detail.

Diary or journal logging

What it is: When you think about it, almost all qualitative research methods aim to help you understand the experiences, lives, and motivations of people. What better way is there to connect with how people think and feel than a journal? Yes, it’s pretty much exactly what it claims to be; a simple note-taking exercise that records regular input, insights, feelings, and thoughts over a period of time.

A survey or focus group captures sentiment at a single point in time. Whereas journal logging gives way to more frequent input without any pressures of time to consider. It’s also more reliable data, as there’s no requirement for people to think about and recall data, as input occurs at the moment. Popular formats include digital diaries, paper journals, and voice journals.

Key parameters are set out from the start. And offer prompts so people know what to record, how often they need to make an entry, the time of day (if relevant), how much they should write, and the purpose or goal of the research.

Best for: Measuring change or impact over time. They’re also a great tool to establish things like:

• Usage scenarios
• Motivations
• Changes in perception
• Behavioral shifts
• Customer journeys

Digital intelligence platforms like Similarweb can give you a framework to outline a story that can be filled in with qualitative research later down the line.

What’s the difference between quantitative and qualitative research methods? Qualitative market research is a type of primary research method that explores how people think and feel about a topic. Quantitative research is statistics-based and analyses numerical data.

What are the different types of qualitative market research? The most popular types of qualitative market research include Focus groups, interviews, ethnography, case studies, grounded theory, observational, online forums, open-ended surveys, biometrics, narrative, thematic analysis, diary or journal logging, thematic analysis, and phenomenological study.

How is qualitative research used in marketing? Qualitative market research serves as a tool that helps marketing teams identify consumer needs, refine product messaging, generate ideas for campaigns, discover new channels, and develop targeted campaigns that resonate with target audiences.

What Types of Questions are Asked in Qualitative Market Research? Qualitative market research often focuses on open-ended questions that allow respondents to provide detailed answers about their attitudes, opinions, and experiences. Examples of questions include: What factors influence your decision to purchase a particular product or service? How do you use a product or service? What do you like or dislike about a product or service?

What are the Limitations of Qualitative Market Research? Qualitative market research can be subjective and may be limited by the number of participants and the amount of time available for research. Additionally, qualitative research does not provide quantitative data, which can be useful for measuring and comparing consumer behavior.

The two research methods you can use to glean these insights are quantitative and qualitative. 

Quantitative research provides you with hard data you can use to find the size and scale of customer sentiment, discover causal relationships between variables, and support generalizations about macro-level populations.

Qualitative market research is an open-ended research method that looks at the reasons and motivations behind customer behavior, at the micro level. Qualitative market research gives you actionable insights you can use to improve everything from your customer service strategies to your products and services.

• What is qualitative market research?

Qualitative market research is an open-ended research method that studies people's behavior and motivations within a specific market. While quantitative research is about hard numbers and analytics, qualitative market research takes a more generalized approach. It focuses on small sample sizes to encourage in-depth analysis of individual customers’ experiences.

The conversational nature of qualitative research is designed to encourage in-depth discussion. For businesses, qualitative market research is a powerful way to understand customers' points of view, as well as their pain points and desires.

• Why is it important to do qualitative market research?

Whether you are a CEO or a project manager, the thoughts and feelings of your customers should matter deeply to you. Through qualitative market research, you can identify the needs of your customers in a more nuanced, in-depth way than is possible with quantitative research. 

Depending on the questions you pose, you can also get a feel for how customers perceive your marketing messages and communications, as well as more broad perceptions of your company as a whole.

If you're planning on launching a new product or service, qualitative market research can help you refine the launch and even make improvements. By using the feedback and insights from your research to make changes leading up to the launch, you are more likely to increase your revenue and receive glowing reviews.

• Advantages of qualitative market research

There are many advantages to qualitative market research. It's flexible, so you can adapt to the quality of information you receive. For example, if the available information isn't providing what you hoped, it's easy to change direction and collect more data using new questions.

Qualitative market research also helps you gather more detailed information than most quantitative data. While quantitative market research gives you metrics, qualitative market research allows you to better understand the subtleties within the data.

Long-term, qualitative market research can reduce customer churn. By conducting regular qualitative market research, businesses can better understand what consumers want (and what they don’t) and learn whether they are fulfilling their needs. This reduces customer churn and helps build a stronger relationship between a business and the people it serves.

• Disadvantages of qualitative market research

The most notable disadvantage of market research is that it’s time-consuming. Depending on the scope of the research and the amount of people dedicated to the project, it can take weeks or even months to complete. If you're working on a tight timeline, or if you have limited resources to dedicate to research, it might not be feasible.

Qualitative market research can also be expensive. While much of the cost will depend on the size and scope of the project, you might also need to hire additional people to help you complete the research.

If you compensate participants for their time (and experts advise some sort of compensation), that's another expense to consider.

Finally, qualitative market research is highly subjective, as the conclusions are drawn by individual researchers and their interpretation and analysis.

• Eight qualitative market research methods

The most common methods for qualitative market research include focus groups, individual interviews, and observations. However, many other methods should be considered as viable options for your market research.

Social media analysis

Social media has become an important part of many people's lives, with millions of people around the world interacting with their favorite platforms on a daily, even hourly, basis. Social media analysis can, therefore, be a powerful way to gather and analyze information.

If your brand is active on social media, take the opportunity to solicit responses from customers who follow you. This can be via a survey feedback form or some sort of direct response from customers.

You can also perform content analysis on social media, scanning comments left by consumers on your posts and checking for frequently used words.

For the most in-depth responses, consider gathering insights directly from the people who follow your pages and regularly interact with you.

Lifestyle immersion

If customer comfort is one of your top priorities as you conduct market research, lifestyle immersion might be the best option.

Lifestyle immersion is a research method that allows the researcher to observe the customer in their natural environment. By observing the participant in a natural setting, you can see their unguarded behavior and learn more about their needs and motives.

Focus groups

Focus groups are a popular method for conducting qualitative market research. Focus groups are typically comprised of 6–10 people, along with a market researcher who functions as a moderator.

During the focus group, participants are encouraged to share their unguarded thoughts and opinions on a product, service, or marketing campaign.

Traditionally, focus groups were held in person, since verbal and non-verbal reactions are an important part of measuring responses. However, web-based focus groups have been gaining popularity in recent years, especially in light of the COVID-19 pandemic. Online focus groups tend to be more cost-effective and convenient for most participants.

Observations

Observations, also known as shop-alongs, involve researchers following participants as they walk through a store. The goal of observations in qualitative market research is to gauge customers’ interactions and reactions to things they encounter, including products, displays, and advertising.

Observations don't require the market researcher to physically accompany participants. Typically, the researcher will observe from a distance or watch a camera feed.

Individual interviews

Individual interviews are a highly personalized method of conducting market research. These interviews are in person, over the phone, or through video-conferencing software.

They tend to be most successful when held as part of a free-flowing conversation that puts the participant at ease and makes them feel comfortable sharing their unfiltered thoughts and opinions. The interviews can be structured or unstructured, depending on the nature of the questions and your overall goals for the project.

Include plenty of open-ended questions in your interview outline to keep the conversation moving. Pay attention throughout the interview to see how the participant responds to the questions and if they seem uncomfortable or ill at ease. If they do, switch gears to make the conversation more relaxed again.

Diary or journal-logging

A diary study, also known as journal-logging, is a research method that aims to collect data about user behaviors, activities, and experiences over a set period.

During the designated reporting period, participants are asked to keep a diary and record specific information about the activities you want to analyze. The data is self-reported by participants when the reporting period is up.

Diary studies can be useful for gathering information about users’ habits and thought patterns. They can also effectively capture attitudes and motivations. However, it can be challenging to recruit dedicated users, since diary studies require greater involvement over a longer period than more traditional market research methods.

Surveys are a popular method of conducting market research. A powerful form of primary research, surveys are endlessly customizable. They can be done:

Over the phone

Via email or other online delivery method

If you opt for an online survey, test the software ahead of time, so you can be sure everything works properly and displays well on mobile devices.

It's also a good idea to run a test survey with a smaller group. This allows you to refine your questions and eliminate any confusing wording.

Ethnographic research

Ethnographic research involves observing participants in their natural environment, primarily how they go about mundane tasks such as cleaning their house or preparing a meal. Unlike observations, ethnography can involve a variety of approaches, including diary studies and video recordings.

The goal of ethnographic research is to understand the social dynamics, beliefs, and behaviors of participants through direct observation and participation in their daily activities. Ethnographic research can take place over an extended period, from a few weeks to a year or more. It's versatile and is best done with the assistance of an experienced ethnographic researcher.

• An example of qualitative market research

One of the main benefits of qualitative market research is its flexibility. No matter what your goal is or what outcome you're hoping for, you can design an effective study.

One example of qualitative market research using a focus group is a cereal company wishing to update the packaging of one of its most popular products. After producing several design concepts, the company opts to commission a series of focus groups to gauge responses to each concept.

During the focus groups, with the help of a moderator, participants discuss each design, evaluating the pros and cons. Based on the feedback received in the focus groups, the cereal company can move forward with the design most appealing to their customers.

• Best practices for qualitative market research

While qualitative research is flexible, there are still best practices to follow. Regardless of which research method you choose, consider these tips when crafting your approach and designing the questions.

Accurately identify research goals

Before embarking on any market research, you should know your end goal. Think about the specific questions you want answered, including the nature of the product or service you wish to refine or develop. Outline your goals and share them with every project stakeholder, including managers and the CEO, if necessary.

Understand your customers

Knowing your customers is vital for accurately targeting survey participants. Your business should have a customer profile that includes basic demographics such as:

Shopping habits

Use this profile to create questions that are useful for your study. When crafted thoughtfully, your questions will identify needs that aren't being met and meet study participants where they are.

Choose the most appropriate research method

There are many ways to conduct qualitative market research, but not all of them might be right for your unique needs. Think about what method will give you the optimal results and work best for the study participants you wish to recruit.

Focus groups are an ever-popular research method, but it isn't always possible to dedicate time and energy to moderating one. A survey or series of observations might be more effective, depending on your available resources and goals.

Use open-ended questions

The goal of qualitative market research is to gain thoughtful responses from participants. Use open-ended questions that require more than a simple yes or no response. The idea is to maintain an open dialogue, even through vehicles such as surveys or focus groups.

Test out questions on yourself and your team members before launching them to participants, so you can be sure they make sense and give people the chance to truly share their thoughts.

• Tips for qualitative data analysis

Qualitative data analysis is rarely a linear process. Since qualitative market research often doesn't result in hard numbers, be flexible in your approach to analysis.

After you finish your research, organize and collate your responses into one location for further analysis. If you have audio or video files, allocate time to transcribe the data, whether that means bringing in a transcriptionist or guiding your team members through the process.

As you go through the responses, become familiar with the data. This will help you better understand your customers and identify any potential gaps in the research. Always involve other stakeholders in the process, not only along the way but also once the final results have been collated. This promotes transparency in the project and improves communication across the board.

Are customer surveys qualitative?

Customer surveys are one method of market research. They can be made qualitative or quantitative, depending on the nature of the questions. They are one of the most popular forms of qualitative market research because they are versatile and highly customizable. Surveys can be done in person or through web software, such as email.

What are qualitative marketing objectives examples?

While quantitative objectives are usually specific and measurable, qualitative marketing objectives are more subjective. They tend to be conceptually broad, such as "we want to learn more about how our customers rank our service compared to our competitors,” "we want to increase brand awareness," and "we want to improve customer satisfaction." It can be helpful to have qualitative and quantitative objectives for your market research, depending on the nature of the project and whether it's related to a specific product or service.

The Complete Guide to Qualitative Market Research

So what exactly is qualitative research? At a glance, this type of research method seeks to gather in-depth data about a phenomenon without focusing on numerical data or on quantities.

But there is much more to this kind of study method. Learn holistically about qualitative market research with this complete guide.

What Defines & Makes Up Qualitative Research?

Qualitative research is centered around experiences, ideas and opinions. As such, it does not focus on statistical or quantitative outcomes. Instead, it seeks out an in-depth understanding of an issue, occurrence or phenomenon.

Thus, this research method zeroes in on the “what” and more importantly, the “why” of a research subject. (Unlike quantitative research, which focuses on the “how much”).

Here are some of the applications of qualitative research:

Understanding an issue in greater depth

Finding the reason behind an occurrence (whether it’s desirable or undesirable)

Uncovering trends in target market opinions

Forming educated solutions to address customer/studied subject concerns

Discovering the causes of certain actions

Qualitative research generally relies on a smaller sample size in order to get a deep read of happenings, causes and motivations. This kind of research method functions through the usage of open-ended and exploratory questions.

Understanding the “why” behind an issue is then used to make decisions on how to resolve the issue or how to improve on an existing productive situation.

Qualitative data must occur in natural environments. This denotes a kind of environment in which participants discuss their opinions at length and at ease, which researchers use to gain deeper knowledge and form inferences around a topic.

Prior to the internet, this kind of research was conducted in-person, but with the advent of the internet and innovations in market research, qualitative data has been collected online. The digital space can also serve as a natural environment.

The Five Main Types of Qualitative Research

Just as with quantitative research, there is not a single approach to conducting qualitative research. On the contrary, there are five main varieties of performing qualitative research. Aside from their methodology, these sub-categories also seek different types of answers and conclusions.

1. Narrative Research

This research is used to form a cohesive story, or narrative, by way of consolidating several events from a small group of people. It involves running in-depth interviews and reading up on documents featuring similar actions as a means of theme-searching.

The point of this is to discover how one narrative is shaped by larger contextual influences. Interviews should be conducted for weeks to months and sometimes even for years. The narrative that the researcher uncovers does not have to be presented in sequential order.

Instead, it should be projected as one with defined themes that attempt to reconcile inconsistent stories. This method can highlight the research study’s ongoing challenges and hardships, which can be used to make any improvements.

2. Ethnographic Research

The most common qualitative research method, ethnography relies on entrenching oneself in various participant environments to extract challenges, goals, themes and cultures.

As the name suggests, it involves taking an ethnographic approach to research, meaning that researchers would experience an environment themselves to draw research. Using this firsthand observation, the researcher would not need to then rely on interviews or surveys.

This approach may seem to be far-fetched where market research is concerned, but it is doable. For example, you’d like to see the effectiveness or frustration that customers face when using your product. Since you can’t follow them home, you can request videos that show them using it. Many big brands have call-outs on their websites (ex: on product pages) for their customers to send in videos of their interactions with the products.

3. Phenomenological Research

This qualitative method entails researchers having to probe a phenomenon or event by bringing lived experiences to light and then interpreting them. In order to achieve this, researchers use several methods in combination.

These include conducting surveys, interviews and utilizing secondary research such as available documents and videos on the studied phenomenon. Additionally, as in ethnographic research, phenomenological research involves visiting places to collect research.

These will help you understand how your participants view your subject of examination. In turn, you will gain insight into the participants’ motivations.

In this research type, you would conduct between 5 and 25 surveys or interviews, then peruse them for themes. Once again, you would scrutinize experiences and sentiment over numerical data.

4. Grounded Theory Research

In contrast to phenomenological research, which seeks to fully form the core of an issue, grounded theory attempts to find explanations (the why) behind an issue. To achieve this, researchers use interviews, surveys and secondary research to form a theory around the issue/occurrence.

The sample of this study tends to be on the larger side, at 20-60 participants. Data extracted from this type of research is interpreted to determine the reasoning behind, for example, heavy usage of or frustration with a product. These types of studies help a business innovate an existing product by getting into the weeds of how it’s used.

5. Action Research

This type of research involves researchers and participants working collaboratively to bring theory to practice. Also called participatory research, collaborative inquiry, emancipatory research and action learning, this method entails the act of “learning by doing.”

This means a group of researchers come together to find and address a problem, resolve it and then study the success of their endeavors. If they underperformed or their outcomes don’t satisfy their expectations, they would then reattempt the process.

In action research , a researcher spends a considerable amount of time on collecting, analyzing, and presenting data in an ongoing, periodic process. This involves researchers coming up with their own surveys and interviews around a subject matter, then presenting their findings to one another to draw conclusions and solutions.

They would put into practice the means to improve a situation and continue measuring their success throughout the process.

Examples of Questions for Qualitative Research

When working within the capacity of any of the above research types, it’s crucial to ask the right questions. Here you’ll find the questions you can use when conducting each of the five types of qualitative research.

Bear in mind that some of these questions will appear to be similar in nature; some are even interchangeable. That is normal, as researchers may search for the same answers, but apply a different approach in their research method.

In any case, all of the below features questions that fit within the larger qualitative research framework.

Learn more about asking insightful market research questions . Here are a few examples of the questions within the five categories:

1. How do people who witnessed domestic violence understand its effects in their own relationships?

    Variable: Views of domestic violence on one’s own relationships

    Demographic: People in relationships, who’ve witnessed domestic violence

    Qualitative Research Type : Narrative

2. What are the lived experiences of working-class Americans between the ages of 20 and 40?

    Variable: Experiences and views of a working-class background

    Demographic: Working-class Americans ages 20-40

3. How do Asian Americans experience reaching out to address mental health concerns?

    Variable: The experiences in seeking out care for mental health

    Demographic: Asian Americans seeking help for mental health

    Qualitative Research Type: Ethnographic

4. What do you enjoy about this product or service?

    Variable: The positive experiences of using a particular product/service

When to Use the Research and How to Analyze It

The qualitative research method has specific use cases. You ought to consider which is best for your particular business, which includes your strategy, your marketing and other facets.

The core of qualitative research is to understand a phenomenon (a problem, an inadequacy, and a slew of other occurrences) including its causes, its motivations, its goals and its solutions. Researchers do this by observing smaller portions of a population.

Researchers should use this form of research whenever you need to get the gist of a particular occurrence or event. It is particularly useful for studying how your target market experiences certain situations and how it feels about them.

There are several more specific ways that elucidate why this research style is valuable if not completely necessary. Here are some of the most crucial ways this method of research is vital:

Helps brands see the emotional connections customers have with them

Allows brands to find gaps in customer experience (CX) and user experience (UX)

Enables brands to create experiences that are more tailored to their target market

Helps businesses understand how they can improve on their product, service or CX

Finds experiences that customers had that highlight sensitive topics/language for them

Shows businesses how customers compare them to their competitors

Identifies possible solutions and innovations based on customer attitudes and experiences

To analyze qualitative research, you should first identify your subject of study and decide on the type of research you need to conduct based on the five types of research that fall under the qualitative category.

Then, brainstorm several questions that you can use to form the base of your studies. During the process make sure to jot down (either digitally or otherwise) your observations. For example, record interviews and store surveys in an organized database.

Make sure you ask open-ended questions in surveys, interviews, focus groups, et al. Aggregate secondary research such as government database documents, articles in your niche,  images,  videos and more.

Search for patterns or similarities within your findings. When you group them together and organize them by demographics, you can start drawing conclusions and proposing solutions.

The Benefits and Drawbacks of Qualitative Research

Qualitative research can be extraordinarily beneficial. But as with other aspects of research and beyond, it too comes with a set of drawbacks. As a business owner, marketer or market researcher, you should know both the pros and cons. Here are some notable ones:

More intimate understanding of context and causation: besides understanding “what” in a granular way, you also learn the “why” and “how” of a particular situation.

Understanding key experiences: Open-ended questions lead to unique answers, exposing things numerical-based surveys can’t answer.

A foundation of deep insights: The design of the study is made to understand how customers relate to particular occurrences, events, ideas and products.

Context-driven: Finding insights on motivation and past behaviors allows researchers to understand what their target market needs and what it tries to avoid.

No need to find and create the correct measuring units: Open-ended questions don’t require a scale, a number range or any other measuring tools — one less thing to worry about.

Smaller sample size: Smaller sample sizes allow researchers to study responses more thoroughly to form more accurate hypotheses and conclusions.

Inspirational : The responses received can also help researchers form new studies.

Flexible and detail-oriented : Since questions aren’t based on scales and other units, you can ask more creative and in-depth questions. Questions focus on details and subtleties for robust insights.

Relies on researcher experience: It relies on the researchers’ experience; not all are familiar with industry topics.

Not statistically representative: Only collects perspective-based research; does not provide statistical representation. Only comparisons, not measurements can be executed.

Difficult to make copies of data.  Individual perspectives make it hard to replicate findings, making it it more difficult to form conclusions.

More likely to have researcher bias: Both conscious or subconscious of the researcher can affect the data. The conclusions they draw can thus be influenced by their bias. (This can be avoided by using controls in data collection.

The Final Word

Market research is a wide-spanning undertaking. It has a wide swath of aspects, practices and applications. As such, researchers should know its main categories and qualitative research is one such category of significance.

As opposed to quantitative research, which has four methods, qualitative research has five — not all of which will be of use to your particular market research needs. In any case, this type of research involves imbuing as much context and particularities around a phenomenon as possible.

As such, researchers should create questions more specific to the aforementioned examples of this article. That is because those are more encompassing, generalized questions that researchers can attempt to answer after conducting all of their research and parsing of the findings.

But prior to that, researchers should ask several related questions around a particular topic and tailor those questions as best as possible to the target audience.

Frequently asked questions

What is qualitative research.

Qualitative research is a type of research that is conducted to gain deep or unexpected insights rather than focusing on numeral or quantitative data.

Why is qualitative research conducted?

Qualitative research is conducted to find the “why” of the research subject, rather than the “what’ of that subject. For example, qualitative research might be conducted to understand an issue more deeply, to understand why something is happening, or to learn how to address a target market’s concerns.

What is narrative research?

Narrative research is a type of research that is used to create an in-depth story about a phenomenon or event. It is conducted by interviewing a small group of people who were directly involved in the event.

How is ethnographic research conducted?

When conducting ethnographic research, the researchers use firsthand observations of an environment to more deeply understand the goals, challenges, or opinions of the target audience.

What is action research?

Action research is a type of qualitative research in which researchers and participants collaborate to better understand a phenomenon. Together the group works to find and solve the problem by gathering information on an ongoing and evolving basis.

The qualitative market research guide: actionable methods for best results

What is qualitative market research, the ethics of qualitative market research, how to conduct qualitative market research, what are the applications of qualitative market research, overcoming the challenges of qualitative market research.

If you’re thinking about skipping qualitative market research and just going with your gut, this article is a must-read.

While some brands and products in the past have won big based on someone’s intuition, it certainly isn’t a reliable recipe for success — because many more who’ve invested based on an instinct, have failed. Hard.

That’s why we want to highlight the importance and value of qualitative market research. It’s what explains why people pick one product over another that seems just as good.

Qualitative research digs into the nuances, offering insights that can significantly impact your marketing approach and product development. Here we’ll show you exactly how you can turn it into your secret weapon.

Qualitative market research goes straight to the core of your customer’s thoughts and feelings. It’s not just about how many people clicked or bought, but why they did it, or even why they didn’t.

This kind of research lets you in on the stories behind the statistics, giving you a more in-depth understanding of your target audience’s behaviors, perceptions and motivations. And with this rich insights and data, you can tailor your products and marketing strategies to truly resonate with your audience.

Here’s a quick rundown of the types of market research out there:

• Quantitative research: Deals with numbers and measurable forms.
• Qualitative research: Focuses on understanding the quality of consumer interactions and thoughts.
• Mixed methods: Combines both quantitative and qualitative research.

It’s good to know qualitative and quantitative research make a great pair – it helps you give context to numbers, and vice versa. And it’s good to know when you could run qualitative research:

• Before your quantitative research ? If you’re grasping for ideas and inspiration, qualitative market research can be a great source. Your respondents will often flag issues or make suggestions that you and your team might never have thought of. And for extra peace of mind, you can follow-up your qualitative research with quantitative studies to make sure that inspo is truly representative.
• After your quantitative research ? Often teams will have run quantitative studies and spotted threads they’d like to pull at and see whether there’s more to learn. This is where qualitative market research comes in – it can add flavor and context to your quant data. And it can be a great way to personalize your data for internal or client signoff.

Of course, there are different ways of gathering qualitative data. So when we talk qualitative research, these are the main methods you’ll come across:

• Ethnographic research: observing your customers in their natural environment, seeing how they live, work, and play.
• Narrative research: collecting stories from individuals to better understand their experiences.
• Phenomenological research: used to understand common experiences among a group of people, researching shared perceptions.
• Grounded theory: developing a theory based on the data you collect, starting with the data and working towards a theory.
• Action research: a collaborative approach, working with groups to identify solutions to problems and implement changes.

Each of these approaches gives you unique insights into the minds and lives of your customers, helping you make more informed decisions that can drive your brand forward.

If you want to know more about the ins and outs of different research types, check out our blog about the difference between quantitative vs qualitative research , and here’s a quick video summary to get you started…

While it’s not exactly mind reading, qualitative market research does touch more on personal thoughts and opinions than, for instance, quantitative research does. That means it requires trust – and that’s where ethics come into play. Here’s what keeping it ethical looks like:

• Participant confidentiality : Keeping the identities of your participants under wraps is a non-negotiable. 
• Informed consent : Participants need to know what they’re getting into, how their insights will be used, and how they can change their involvement.
• Sensitive information : Any data that could be considered sensitive deserves extra protection and consideration.

Data isn’t high quality when it isn’t ethical, and vice versa. If your respondents don’t feel that their answers will be handled with care, they might not answer honestly – if at all.

At Attest, we’re all about making sure your insights are built on a solid foundation of excellent data quality, trust and transparency – for both you and your respondents. 

Because what’s the point of qualitative research if you can’t trust the results? Check out how we assure data quality that you can rely on.

The research you do should be the foundation of the actions that follow — don’t just conduct research for the sake of it. Choosing the right qualitative research methods and tools is crucial, but there’s more to it.

By following the steps below, you’ll not only gather rich, qualitative data but also pave the way for meaningful changes in your product development, marketing strategy, and overall brand experience. 

1. Create a research plan

When you conduct qualitative research, or any kind really, the steps you take should be based on your research objectives, and related to the actual changes you might be making. This is what makes market research crucial for marketing experts : it shows you which actions to take, instead of just doing creative guesswork. 

First, decide on your qualitative research methods—will you go for surveys, focus groups, or a mix? Define clear objectives. What do you want to learn? Keep in mind how to balance your research approach: you can opt for direct exploration for fresh insights, monadic testing for focused feedback, sequential monadic testing for comparative insights, or discrete choice testing to understand preferences. Each method has its place, and combining them strategically can offer a fuller picture of your market.

Next up, consider your sampling methods. Who are your ideal participants? Where can you find them? (Hint: we help you with this!)

Once you know what to ask and who you’ll be speaking to, it’s time to start crafting your survey — and using our templates makes that even easier. Take your pick and start tweaking. 

The final step of your research plan, is choosing which qualitative market research tool to choose for. The steps below give you some guidance on what to look for.

2. Recruit the right participants

The power of qualitative research lies not in the most fancy tools, but in the quality of your participants. 

You’re looking for individuals who reflect your target audience or represent a new market you’re exploring. The key is to ensure diversity and relevance to get a comprehensive understanding of consumer behavior and opinions. Read more about how we help you get in touch with the right people — picking from an audience of 125 million people in 59 markets spread across the globe.

3. Conduct interviews, surveys or focus group research

Jumping into your audience’s world, interviews, surveys, and focus groups are essential tools in your research kit. But how do these qualitative market research methods add value?

• One-on-one interviews offer a closer look into what your consumers are thinking and feeling, providing valuable insights into their personal experiences and expectations. This intimate format fosters detailed conversations that can uncover deep-seated motivations and stories.
• Surveys allow for a broad reach, enabling you to connect with a wide audience very quickly to collect various data points. This method is great for identifying trends, preferences and behaviors on a larger scale.
• Focus groups, on the other hand, bring a unique dynamic. In these sessions, participants’ interactions can generate new insights and perspectives, offering a diverse view of your product or service. This collaborative environment encourages research participants to build on each other’s ideas, revealing insights that might not emerge in individual settings.

Remember: you don’t have to limit yourself to only one option – but pick a mix that works best for your research goals, and your audience. Their participation is key here.

4. Conduct observational research (optional)

Now this is optional, but if you want an extra layer to your research process, observational research is a great supplement to your qualitative study.

Instead of just hearing what your target audience is thinking, you are going to see how it affects their actions, by tracking how they interact with your products, navigate your stores or use your website.

Watching from a distance, you might discover that consumers use your product in ways you hadn’t imagined. It might also clarify some statements you heard or uncovered during the survey or interview phase – observational research can unearth gems of insights that are invisible in one-on-one conversations or online focus groups.

Of course, this approach requires patience and a non-intrusive stance. You don’t want to influence people, and it’s not easy to do it at a large scale – but in some scenarios adding an extra research method like this certainly gives extra depth to your findings. 

5. Analyze your research data

With data in hand, it’s time to sift through the stories and sentiments to find patterns and themes. Qualitative data analysis can be complex, but it’s where you begin to understand the ‘why’ behind the behaviors that drive your customers’ choices. 

Don’t just use qualitative insights to confirm your hopes and beliefs. Actively look for commonalities, differences, and surprising insights that can guide your strategy.

6. Report and communicate findings to key stakeholders

This is the springboard to action. If you can package your findings in a way that resonates with your team, management, or clients, you’re one step closer to meaningful and impactful changes. 

Clear, compelling reporting translates your research into actionable insights – and our tool helps you get them. 

Share stories, highlight key themes, and suggest next steps. Make your qualitative research findings a cornerstone for your decision-making and strategy development.

Qualitative research in marketing: definition, methods and examples

• Share this article

Qualitative research allows businesses to determine customers’ needs, generate ideas on improving the product or expanding the product line, clarify the marketing mix and understand how the product would fit into customers’ lifestyles. The research will be useful for businesses of any size and type. For example, entrepreneurs can use qualitative research to gain insight into customers’ feelings, values, and impressions of the product or service. With qualitative research, you can understand the reasons and motives of customers’ reactions and use this information to create marketing and sales strategies .

The research can also help you design products and services that meet the requirements of your target audience. For instance, imagine you are a restaurant owner and want to introduce a new menu; you can conduct qualitative research and invite local residents to give you feedback on the food, service, and pricing. This approach will increase your chances of success.

Qualitative research studies the motives that determine consumer behavior by employing observation methods and unstructured questioning techniques, such as individual in-depth interviews and group discussions. The approach involves the collection and analysis of primary and secondary non-numerical data. The goal of qualitative research is to understand the underlying reasons for making purchasing decisions and learn about customers’ values and beliefs. 

Qualitative research asks open-ended questions beginning with the words “what”, “how”, and “why” to get feedback concerning a new product or service before the launch or development phase. This method reveals customers’ perceptions of the brand, buyers’ needs, advantages, and drawbacks of the product or service. Furthermore, it helps evaluate promotional materials and predict how the product or service can influence the lives of your customers. 

This research method emerged in the early 1940s when American sociologist Paul Lazarsfeld introduced focus group interviews to study the impact of propaganda during World War II. In the late 1940s, American psychologist and marketing expert Ernest Dichter developed a new type of consumer research called motivational research. Dichter used Freudian psychoanalytic concepts to understand the motives of consumer behavior. He conducted in-depth interviews to learn more about customers’ needs and attitudes towards certain products. 

In the 1960s, marketing academic John Howard began studying consumer behavior from the perspective of social sciences, including psychology, anthropology, and economics. At the same time, market researchers focused on the emotions, feelings, and attitudinal elements of consumption. As a result, in-depth interviews, video-recorded focus groups, and computer-assisted telephone interviews became prevalent qualitative research techniques. 

With the advent of the Internet and mobile devices, qualitative research has undergone numerous changes. Today the Internet allows researchers to conduct surveys on a much larger scale. The marketers can use hyper-segmentation and hyper-personalization to launch targeted advertising campaigns, utilize market research analysis software and gather customer opinions using social media analysis. Let us take a detailed look at the basic methods of qualitative research.

The most common qualitative research methods include focus groups, individual interviews, observations, in-home videos, lifestyle immersion, ethnographic research, online sentence completion, and word association. We will consider each of them in more detail below.

Focus groups

Focus groups are discussions dedicated to a specific product and its marketing strategies . The groups typically consist of 6-10 people and a moderator who encourages them to express their opinions and feelings about the product. Usually, focus groups are held in-person to study consumers’ verbal and non-verbal reactions to the product or advertising campaign. 

This method has several applications, including testing marketing programs, evaluating the overall concept for a product, examining the copy and images of the advertisements, and analyzing the new types of product packaging. Nowadays, in-person focus groups are losing popularity, while online discussions via video conferencing tools are attracting a lot of attention from researchers. 

Social media analysis

Social media and mobile devices give brands more opportunities to gather and analyze information. Customers now interact directly with brands on social media platforms where they spend their free time. Content analysis of Facebook posts, comments, tweets, YouTube videos , and Instagram photos allows brands to track consumers’ activities, locations, and commonly used words. 

You can ask for users’ feedback , encourage them to fill out a brief survey, or engage with customers to inform them of your marketing plans and the development of new products. Furthermore, the qualitative research participants can provide additional contextual information like photos and videos, which gives a better understanding of their thoughts and attitudes.

Individual interviews

An individual interview is usually conducted in person, over the phone, or via video conferencing platforms. The interviewer asks the existing customer a number of questions to determine his motivation to buy a particular product. One-to-one interviews are held as a free-flowing conversation and include open-ended questions. The interviews can be flexible, semi-structured, and unstructured. You can ask about the customer’s frustrations concerning the product, motivations and reasons for purchase, and the sources of information from which they learned about the product.

Observations

Observations allow researchers to see how the customers react to the products in the store and analyze their shopping behavior and purchase experience. This method is more effective than written surveys as it provides better insight into consumer reactions. For example, the researchers can observe how customers stop outside the store, what attracts them to the shop window and which way they walk once they enter the store. In addition, observations help determine problems related to product placement on store shelves, clutter, or products that are out of stock. You can also collect customer feedback to improve some aspects of the shopping process, like packaging design.

In-home videos 

In-home videos allow researchers to watch how customers engage with the product in the comfort of their own homes. Using this method, you can monitor user behavior in a natural and relaxed environment. Thus, you can have a better picture of the ways people use your product. The customers can keep video diaries or film the videos with detailed comments concerning your product. You can store the qualitative content in one place and create an insight hub to analyze and reuse the collected information in the future.

Lifestyle immersion

Lifestyle immersion is another method that allows obtaining customer feedback in a comfortable environment. Immersion refers to the researcher’s profound personal involvement in a customer’s life. For instance, the researcher visits an event, such as a party or family gathering, and observes the user’s reactions and behaviors in a familiar setting. Watching how users speak to their family and friends is an increasingly effective technique that allows learning more about their needs, challenges, and motives. 

Ethnographic research

Ethnography is a type of research that originates from 20th-century anthropology and involves observing people in a natural environment rather than a lab. Namely, the researchers watch how respondents cope with their daily tasks, such as grocery shopping or preparing dinner. This helps see what people actually do instead of what they claim to do. 

Ethnography applies a variety of approaches, including direct observation, video recordings, diary studies, and photography. Researchers can observe the user’s behavior at home, at the workplace, or with their family or friends. Passive observation as a method of ethnographic research implies following and watching users without interacting with them or interfering with their actions. Active observation, in contrast, entails working or cooperating with consumers, asking them questions about a product or service, and joining their team or group.

Online sentence completion and word association

Sentence completion is a projective technique used in qualitative research to allow customers to express their opinions and feelings. According to this method, the respondents receive the survey with unfinished sentences. They should complete sentences that describe the product or find the words that would be appropriate in the context of the sentence. With this method, the researcher can put qualitative data in a structured form. 

Word association is a similar technique that helps researchers gather information about brand awareness , images, and associations related to a specific product or brand. The respondents are given the trigger words and instructed to write the first word, association, or image that comes to mind. In contrast to the interviews and focus groups, sentence completion and word association techniques can reach more people when conducted online. Moreover, it takes less time to analyze the results and understand users’ perceptions. 

Once you have learned about the most widely used qualitative research methods, it is time to plan the research process step by step. 

The success of your research outcomes greatly depends on adequate planning and appropriate strategy. Here we will list some general guidelines on how to conduct qualitative research.

Determine research objectives

The first step to designing or running qualitative market research is understanding the goals you want to achieve with your study. In particular, the research objectives might include discovering the existing or potential product or brand positioning , understanding perceptions about the company or product, investigating how people react to advertising campaigns,  packaging or design, evaluating website usability, and identifying strengths and weaknesses in the product. The absence of clear objectives would create challenges for the researcher as qualitative research involves open-ended questions and in-depth replies that are difficult to interpret and analyze directly.

Choose the methodology to conduct the research

Determine the most suitable method to perform market research taking into account demographics, geographical location of your target audience, lifestyle behaviors, and the product that is being examined. Market researchers usually collaborate with professional recruiters who find and screen the participants. A significant part of the researcher’s work is to develop a list of topics for discussion in small groups. You need to involve moderators who would spend from 90 to 120 minutes with the group asking questions, observing their reactions, and analyzing behavior.

Investigate various data collection methods

Once you have chosen the observation method, you need to involve a moderator to examine the participants’ behavior and take notes. This approach usually requires a video camera or a one-way mirror. You can also combine qualitative and quantitative research to collect numerical data and analyze metrics together with customers’ replies and observation results. 

When running focus groups, you can either organize one discussion with eight to ten participants or a series of online meetings which will last three-four days. Respondents will answer the questions from the moderator or react to prerecorded videos.

When you conduct one-on-one interviews, you need to speak with the respondents on the phone or organize a personal meeting. This method will be suitable if you want customers to try the product and share their impressions.

Analyze the collected data

Researchers will typically need a few days to a few weeks to collect the information. Then researchers will examine the data to provide responses to your questions. The next step is qualitative coding or the technique of categorizing the findings to identify themes and patterns. The specialists might also include the statistics to explain what the data is indicating. Besides, the report might contain a narrative analysis of underlying messages and phrasings.

Study the report and recommendations

The final step is to review the report provided by the researchers. It can be a written document or video recording. The paper, based on MECE principles , will help you group the patterns and similarities and sort them according to demographics and other customer characteristics. The document will contain specific recommendations, so you can draw conclusions and start making improvements to your product marketing strategy .

In the next section of this article, we will review how famous brands have put qualitative research methods into practice.

Qualitative market research helps brands strengthen their reputation and credibility, segment customers , identify market trends, increase awareness, rebrand products , and get feedback from the consumers on their preferences. Let us discover how McDonald’s, Starbucks, and LEGO use data to confront tough competition.

When conducting market research, McDonald’s asks the customers several critical questions regarding best-performing products, the most appropriate pricing , the effective advertisements, and the most attended restaurants. Finding answers to these questions allows for analyzing whether the company managed to expand its customer base. 

Furthermore, McDonald’s collects customer feedback to improve the products. In particular, many customers were disappointed with the lack of healthy and organic options on the menu. As a result, the company added apple slices and other healthy items to the menu and launched an advertising campaign to show that chicken nuggets and burgers were made of real meat.

Starbucks encourages customers to share feedback on the official site and contribute ideas via Twitter . The company monitors social media, tracks cultural trends, and offers customers to test the products in the stores. From 2008 to 2018, Starbucks used the My Starbucks Idea platform to collect ideas and continuously improve its products. The company implemented over 275 consumer ideas, including recommendations about new products and methods to improve corporate responsibility.

Some years before, LEGO was considered to be primarily a boy-oriented company. Then LEGO decided to promote inclusivity and create toys targeted at all genders. The company conducted research involving 3,500 girls and their parents to examine children’s behavior while playing with toys. Later LEGO used the collected data to determine the size of the figures and create bright packaging for the new toy line called “Friends” which was designed specifically for girls.

Companies would not create new offers, improve their existing products, satisfy the needs of their customers, or solve the most difficult challenges without market research. Qualitative research will help you obtain a clear understanding of your target customers, recognize the emotional connections to your brand, identify potential obstacles to purchase and features that are missing in your offer, and as a result, develop an outstanding product.

Qualitative Research Methods: Types, Analysis + Examples

Qualitative research is based on the disciplines of social sciences like psychology, sociology, and anthropology. Therefore, the qualitative research methods allow for in-depth and further probing and questioning of respondents based on their responses. The interviewer/researcher also tries to understand their motivation and feelings. Understanding how your audience makes decisions can help derive conclusions in market research.

What is qualitative research?

Qualitative research is defined as a market research method that focuses on obtaining data through open-ended and conversational communication .

This method is about “what” people think and “why” they think so. For example, consider a convenience store looking to improve its patronage. A systematic observation concludes that more men are visiting this store. One good method to determine why women were not visiting the store is conducting an in-depth interview method with potential customers.

For example, after successfully interviewing female customers and visiting nearby stores and malls, the researchers selected participants through random sampling . As a result, it was discovered that the store didn’t have enough items for women.

So fewer women were visiting the store, which was understood only by personally interacting with them and understanding why they didn’t visit the store because there were more male products than female ones.

Types of qualitative research methods with examples

Qualitative research methods are designed in a manner that helps reveal the behavior and perception of a target audience with reference to a particular topic. There are different types of qualitative research methods, such as in-depth interviews, focus groups, ethnographic research, content analysis, and case study research that are usually used.

The results of qualitative methods are more descriptive, and the inferences can be drawn quite easily from the obtained data .

Qualitative research methods originated in the social and behavioral research sciences. Today, our world is more complicated, and it is difficult to understand what people think and perceive. Online research methods make it easier to understand that as it is a more communicative and descriptive analysis .

The following are the qualitative research methods that are frequently used. Also, read about qualitative research examples :

1. One-on-one interview

Conducting in-depth interviews is one of the most common qualitative research methods. It is a personal interview that is carried out with one respondent at a time. This is purely a conversational method and invites opportunities to get details in depth from the respondent.

One of the advantages of this method is that it provides a great opportunity to gather precise data about what people believe and their motivations . If the researcher is well experienced, asking the right questions can help him/her collect meaningful data. If they should need more information, the researchers should ask such follow-up questions that will help them collect more information.

These interviews can be performed face-to-face or on the phone and usually can last between half an hour to two hours or even more. When the in-depth interview is conducted face to face, it gives a better opportunity to read the respondents’ body language and match the responses.

2. Focus groups

A focus group is also a commonly used qualitative research method used in data collection. A focus group usually includes a limited number of respondents (6-10) from within your target market.

The main aim of the focus group is to find answers to the “why, ” “what,” and “how” questions. One advantage of focus groups is you don’t necessarily need to interact with the group in person. Nowadays, focus groups can be sent an online survey on various devices, and responses can be collected at the click of a button.

Focus groups are an expensive method as compared to other online qualitative research methods. Typically, they are used to explain complex processes. This method is very useful for market research on new products and testing new concepts.

3. Ethnographic research

Ethnographic research is the most in-depth observational research method that studies people in their naturally occurring environment.

This method requires the researchers to adapt to the target audiences’ environments, which could be anywhere from an organization to a city or any remote location. Here, geographical constraints can be an issue while collecting data.

This research design aims to understand the cultures, challenges, motivations, and settings that occur. Instead of relying on interviews and discussions, you experience the natural settings firsthand.

This type of research method can last from a few days to a few years, as it involves in-depth observation and collecting data on those grounds. It’s a challenging and time-consuming method and solely depends on the researcher’s expertise to analyze, observe, and infer the data.

4. Case study research

T he case study method has evolved over the past few years and developed into a valuable quality research method. As the name suggests, it is used for explaining an organization or an entity.

This type of research method is used within a number of areas like education, social sciences, and similar. This method may look difficult to operate; however , it is one of the simplest ways of conducting research as it involves a deep dive and thorough understanding of the data collection methods and inferring the data.

5. Record keeping

This method makes use of the already existing reliable documents and similar sources of information as the data source. This data can be used in new research. This is similar to going to a library. There, one can go over books and other reference material to collect relevant data that can likely be used in the research.

6. Process of observation

Qualitative Observation is a process of research that uses subjective methodologies to gather systematic information or data. Since the focus on qualitative observation is the research process of using subjective methodologies to gather information or data. Qualitative observation is primarily used to equate quality differences.

Qualitative observation deals with the 5 major sensory organs and their functioning – sight, smell, touch, taste, and hearing. This doesn’t involve measurements or numbers but instead characteristics.

Explore Insightfully Contextual Inquiry in Qualitative Research

Qualitative research: data collection and analysis

A. qualitative data collection.

Qualitative data collection allows collecting data that is non-numeric and helps us to explore how decisions are made and provide us with detailed insight. For reaching such conclusions the data that is collected should be holistic, rich, and nuanced and findings to emerge through careful analysis.

• Whatever method a researcher chooses for collecting qualitative data, one aspect is very clear the process will generate a large amount of data. In addition to the variety of methods available, there are also different methods of collecting and recording the data.

For example, if the qualitative data is collected through a focus group or one-to-one discussion, there will be handwritten notes or video recorded tapes. If there are recording they should be transcribed and before the process of data analysis can begin.

• As a rough guide, it can take a seasoned researcher 8-10 hours to transcribe the recordings of an interview, which can generate roughly 20-30 pages of dialogues. Many researchers also like to maintain separate folders to maintain the recording collected from the different focus group. This helps them compartmentalize the data collected.
• In case there are running notes taken, which are also known as field notes, they are helpful in maintaining comments, environmental contexts, environmental analysis , nonverbal cues etc. These filed notes are helpful and can be compared while transcribing audio recorded data. Such notes are usually informal but should be secured in a similar manner as the video recordings or the audio tapes.

B. Qualitative data analysis

Qualitative data analysis such as notes, videos, audio recordings images, and text documents. One of the most used methods for qualitative data analysis is text analysis.

Text analysis is a  data analysis method that is distinctly different from all other qualitative research methods, where researchers analyze the social life of the participants in the research study and decode the words, actions, etc. 

There are images also that are used in this research study and the researchers analyze the context in which the images are used and draw inferences from them. In the last decade, text analysis through what is shared on social media platforms has gained supreme popularity.

Characteristics of qualitative research methods

• Qualitative research methods usually collect data at the sight, where the participants are experiencing issues or research problems . These are real-time data and rarely bring the participants out of the geographic locations to collect information.
• Qualitative researchers typically gather multiple forms of data, such as interviews, observations, and documents, rather than rely on a single data source .
• This type of research method works towards solving complex issues by breaking down into meaningful inferences, that is easily readable and understood by all.
• Since it’s a more communicative method, people can build their trust on the researcher and the information thus obtained is raw and unadulterated.

Qualitative research method case study

Let’s take the example of a bookstore owner who is looking for ways to improve their sales and customer outreach. An online community of members who were loyal patrons of the bookstore were interviewed and related questions were asked and the questions were answered by them.

At the end of the interview, it was realized that most of the books in the stores were suitable for adults and there were not enough options for children or teenagers.

By conducting this qualitative research the bookstore owner realized what the shortcomings were and what were the feelings of the readers. Through this research now the bookstore owner can now keep books for different age categories and can improve his sales and customer outreach.

Such qualitative research method examples can serve as the basis to indulge in further quantitative research , which provides remedies.

When to use qualitative research

Researchers make use of qualitative research techniques when they need to capture accurate, in-depth insights. It is very useful to capture “factual data”. Here are some examples of when to use qualitative research.

• Developing a new product or generating an idea.
• Studying your product/brand or service to strengthen your marketing strategy.
• To understand your strengths and weaknesses.
• Understanding purchase behavior.
• To study the reactions of your audience to marketing campaigns and other communications.
• Exploring market demographics, segments, and customer care groups.
• Gathering perception data of a brand, company, or product.

Qualitative Research

Qualitative research is a type of research methodology that focuses on exploring and understanding people’s beliefs, attitudes, behaviors, and experiences through the collection and analysis of non-numerical data. It seeks to answer research questions through the examination of subjective data, such as interviews, focus groups, observations, and textual analysis.

Qualitative research aims to uncover the meaning and significance of social phenomena, and it typically involves a more flexible and iterative approach to data collection and analysis compared to quantitative research. Qualitative research is often used in fields such as sociology, anthropology, psychology, and education.

Qualitative Research Methods

Qualitative Research Methods are as follows:

One-to-One Interview

This method involves conducting an interview with a single participant to gain a detailed understanding of their experiences, attitudes, and beliefs. One-to-one interviews can be conducted in-person, over the phone, or through video conferencing. The interviewer typically uses open-ended questions to encourage the participant to share their thoughts and feelings. One-to-one interviews are useful for gaining detailed insights into individual experiences.

Focus Groups

This method involves bringing together a group of people to discuss a specific topic in a structured setting. The focus group is led by a moderator who guides the discussion and encourages participants to share their thoughts and opinions. Focus groups are useful for generating ideas and insights, exploring social norms and attitudes, and understanding group dynamics.

Ethnographic Studies

This method involves immersing oneself in a culture or community to gain a deep understanding of its norms, beliefs, and practices. Ethnographic studies typically involve long-term fieldwork and observation, as well as interviews and document analysis. Ethnographic studies are useful for understanding the cultural context of social phenomena and for gaining a holistic understanding of complex social processes.

Text Analysis

This method involves analyzing written or spoken language to identify patterns and themes. Text analysis can be quantitative or qualitative. Qualitative text analysis involves close reading and interpretation of texts to identify recurring themes, concepts, and patterns. Text analysis is useful for understanding media messages, public discourse, and cultural trends.

This method involves an in-depth examination of a single person, group, or event to gain an understanding of complex phenomena. Case studies typically involve a combination of data collection methods, such as interviews, observations, and document analysis, to provide a comprehensive understanding of the case. Case studies are useful for exploring unique or rare cases, and for generating hypotheses for further research.

Process of Observation

This method involves systematically observing and recording behaviors and interactions in natural settings. The observer may take notes, use audio or video recordings, or use other methods to document what they see. Process of observation is useful for understanding social interactions, cultural practices, and the context in which behaviors occur.

Record Keeping

This method involves keeping detailed records of observations, interviews, and other data collected during the research process. Record keeping is essential for ensuring the accuracy and reliability of the data, and for providing a basis for analysis and interpretation.

This method involves collecting data from a large sample of participants through a structured questionnaire. Surveys can be conducted in person, over the phone, through mail, or online. Surveys are useful for collecting data on attitudes, beliefs, and behaviors, and for identifying patterns and trends in a population.

Qualitative data analysis is a process of turning unstructured data into meaningful insights. It involves extracting and organizing information from sources like interviews, focus groups, and surveys. The goal is to understand people’s attitudes, behaviors, and motivations

Qualitative Research Analysis Methods

Qualitative Research analysis methods involve a systematic approach to interpreting and making sense of the data collected in qualitative research. Here are some common qualitative data analysis methods:

Thematic Analysis

This method involves identifying patterns or themes in the data that are relevant to the research question. The researcher reviews the data, identifies keywords or phrases, and groups them into categories or themes. Thematic analysis is useful for identifying patterns across multiple data sources and for generating new insights into the research topic.

Content Analysis

This method involves analyzing the content of written or spoken language to identify key themes or concepts. Content analysis can be quantitative or qualitative. Qualitative content analysis involves close reading and interpretation of texts to identify recurring themes, concepts, and patterns. Content analysis is useful for identifying patterns in media messages, public discourse, and cultural trends.

Discourse Analysis

This method involves analyzing language to understand how it constructs meaning and shapes social interactions. Discourse analysis can involve a variety of methods, such as conversation analysis, critical discourse analysis, and narrative analysis. Discourse analysis is useful for understanding how language shapes social interactions, cultural norms, and power relationships.

Grounded Theory Analysis

This method involves developing a theory or explanation based on the data collected. Grounded theory analysis starts with the data and uses an iterative process of coding and analysis to identify patterns and themes in the data. The theory or explanation that emerges is grounded in the data, rather than preconceived hypotheses. Grounded theory analysis is useful for understanding complex social phenomena and for generating new theoretical insights.

Narrative Analysis

This method involves analyzing the stories or narratives that participants share to gain insights into their experiences, attitudes, and beliefs. Narrative analysis can involve a variety of methods, such as structural analysis, thematic analysis, and discourse analysis. Narrative analysis is useful for understanding how individuals construct their identities, make sense of their experiences, and communicate their values and beliefs.

Phenomenological Analysis

This method involves analyzing how individuals make sense of their experiences and the meanings they attach to them. Phenomenological analysis typically involves in-depth interviews with participants to explore their experiences in detail. Phenomenological analysis is useful for understanding subjective experiences and for developing a rich understanding of human consciousness.

Comparative Analysis

This method involves comparing and contrasting data across different cases or groups to identify similarities and differences. Comparative analysis can be used to identify patterns or themes that are common across multiple cases, as well as to identify unique or distinctive features of individual cases. Comparative analysis is useful for understanding how social phenomena vary across different contexts and groups.

Applications of Qualitative Research

Qualitative research has many applications across different fields and industries. Here are some examples of how qualitative research is used:

• Market Research: Qualitative research is often used in market research to understand consumer attitudes, behaviors, and preferences. Researchers conduct focus groups and one-on-one interviews with consumers to gather insights into their experiences and perceptions of products and services.
• Health Care: Qualitative research is used in health care to explore patient experiences and perspectives on health and illness. Researchers conduct in-depth interviews with patients and their families to gather information on their experiences with different health care providers and treatments.
• Education: Qualitative research is used in education to understand student experiences and to develop effective teaching strategies. Researchers conduct classroom observations and interviews with students and teachers to gather insights into classroom dynamics and instructional practices.
• Social Work : Qualitative research is used in social work to explore social problems and to develop interventions to address them. Researchers conduct in-depth interviews with individuals and families to understand their experiences with poverty, discrimination, and other social problems.
• Anthropology : Qualitative research is used in anthropology to understand different cultures and societies. Researchers conduct ethnographic studies and observe and interview members of different cultural groups to gain insights into their beliefs, practices, and social structures.
• Psychology : Qualitative research is used in psychology to understand human behavior and mental processes. Researchers conduct in-depth interviews with individuals to explore their thoughts, feelings, and experiences.
• Public Policy : Qualitative research is used in public policy to explore public attitudes and to inform policy decisions. Researchers conduct focus groups and one-on-one interviews with members of the public to gather insights into their perspectives on different policy issues.

How to Conduct Qualitative Research

Here are some general steps for conducting qualitative research:

• Identify your research question: Qualitative research starts with a research question or set of questions that you want to explore. This question should be focused and specific, but also broad enough to allow for exploration and discovery.
• Select your research design: There are different types of qualitative research designs, including ethnography, case study, grounded theory, and phenomenology. You should select a design that aligns with your research question and that will allow you to gather the data you need to answer your research question.
• Recruit participants: Once you have your research question and design, you need to recruit participants. The number of participants you need will depend on your research design and the scope of your research. You can recruit participants through advertisements, social media, or through personal networks.
• Collect data: There are different methods for collecting qualitative data, including interviews, focus groups, observation, and document analysis. You should select the method or methods that align with your research design and that will allow you to gather the data you need to answer your research question.
• Analyze data: Once you have collected your data, you need to analyze it. This involves reviewing your data, identifying patterns and themes, and developing codes to organize your data. You can use different software programs to help you analyze your data, or you can do it manually.
• Interpret data: Once you have analyzed your data, you need to interpret it. This involves making sense of the patterns and themes you have identified, and developing insights and conclusions that answer your research question. You should be guided by your research question and use your data to support your conclusions.
• Communicate results: Once you have interpreted your data, you need to communicate your results. This can be done through academic papers, presentations, or reports. You should be clear and concise in your communication, and use examples and quotes from your data to support your findings.

Examples of Qualitative Research

Here are some real-time examples of qualitative research:

• Customer Feedback: A company may conduct qualitative research to understand the feedback and experiences of its customers. This may involve conducting focus groups or one-on-one interviews with customers to gather insights into their attitudes, behaviors, and preferences.
• Healthcare : A healthcare provider may conduct qualitative research to explore patient experiences and perspectives on health and illness. This may involve conducting in-depth interviews with patients and their families to gather information on their experiences with different health care providers and treatments.
• Education : An educational institution may conduct qualitative research to understand student experiences and to develop effective teaching strategies. This may involve conducting classroom observations and interviews with students and teachers to gather insights into classroom dynamics and instructional practices.
• Social Work: A social worker may conduct qualitative research to explore social problems and to develop interventions to address them. This may involve conducting in-depth interviews with individuals and families to understand their experiences with poverty, discrimination, and other social problems.
• Anthropology : An anthropologist may conduct qualitative research to understand different cultures and societies. This may involve conducting ethnographic studies and observing and interviewing members of different cultural groups to gain insights into their beliefs, practices, and social structures.
• Psychology : A psychologist may conduct qualitative research to understand human behavior and mental processes. This may involve conducting in-depth interviews with individuals to explore their thoughts, feelings, and experiences.
• Public Policy: A government agency or non-profit organization may conduct qualitative research to explore public attitudes and to inform policy decisions. This may involve conducting focus groups and one-on-one interviews with members of the public to gather insights into their perspectives on different policy issues.

Purpose of Qualitative Research

The purpose of qualitative research is to explore and understand the subjective experiences, behaviors, and perspectives of individuals or groups in a particular context. Unlike quantitative research, which focuses on numerical data and statistical analysis, qualitative research aims to provide in-depth, descriptive information that can help researchers develop insights and theories about complex social phenomena.

Qualitative research can serve multiple purposes, including:

• Exploring new or emerging phenomena : Qualitative research can be useful for exploring new or emerging phenomena, such as new technologies or social trends. This type of research can help researchers develop a deeper understanding of these phenomena and identify potential areas for further study.
• Understanding complex social phenomena : Qualitative research can be useful for exploring complex social phenomena, such as cultural beliefs, social norms, or political processes. This type of research can help researchers develop a more nuanced understanding of these phenomena and identify factors that may influence them.
• Generating new theories or hypotheses: Qualitative research can be useful for generating new theories or hypotheses about social phenomena. By gathering rich, detailed data about individuals’ experiences and perspectives, researchers can develop insights that may challenge existing theories or lead to new lines of inquiry.
• Providing context for quantitative data: Qualitative research can be useful for providing context for quantitative data. By gathering qualitative data alongside quantitative data, researchers can develop a more complete understanding of complex social phenomena and identify potential explanations for quantitative findings.

When to use Qualitative Research

Here are some situations where qualitative research may be appropriate:

• Exploring a new area: If little is known about a particular topic, qualitative research can help to identify key issues, generate hypotheses, and develop new theories.
• Understanding complex phenomena: Qualitative research can be used to investigate complex social, cultural, or organizational phenomena that are difficult to measure quantitatively.
• Investigating subjective experiences: Qualitative research is particularly useful for investigating the subjective experiences of individuals or groups, such as their attitudes, beliefs, values, or emotions.
• Conducting formative research: Qualitative research can be used in the early stages of a research project to develop research questions, identify potential research participants, and refine research methods.
• Evaluating interventions or programs: Qualitative research can be used to evaluate the effectiveness of interventions or programs by collecting data on participants’ experiences, attitudes, and behaviors.

Characteristics of Qualitative Research

Qualitative research is characterized by several key features, including:

• Focus on subjective experience: Qualitative research is concerned with understanding the subjective experiences, beliefs, and perspectives of individuals or groups in a particular context. Researchers aim to explore the meanings that people attach to their experiences and to understand the social and cultural factors that shape these meanings.
• Use of open-ended questions: Qualitative research relies on open-ended questions that allow participants to provide detailed, in-depth responses. Researchers seek to elicit rich, descriptive data that can provide insights into participants’ experiences and perspectives.
• Sampling-based on purpose and diversity: Qualitative research often involves purposive sampling, in which participants are selected based on specific criteria related to the research question. Researchers may also seek to include participants with diverse experiences and perspectives to capture a range of viewpoints.
• Data collection through multiple methods: Qualitative research typically involves the use of multiple data collection methods, such as in-depth interviews, focus groups, and observation. This allows researchers to gather rich, detailed data from multiple sources, which can provide a more complete picture of participants’ experiences and perspectives.
• Inductive data analysis: Qualitative research relies on inductive data analysis, in which researchers develop theories and insights based on the data rather than testing pre-existing hypotheses. Researchers use coding and thematic analysis to identify patterns and themes in the data and to develop theories and explanations based on these patterns.
• Emphasis on researcher reflexivity: Qualitative research recognizes the importance of the researcher’s role in shaping the research process and outcomes. Researchers are encouraged to reflect on their own biases and assumptions and to be transparent about their role in the research process.

Advantages of Qualitative Research

Qualitative research offers several advantages over other research methods, including:

• Depth and detail: Qualitative research allows researchers to gather rich, detailed data that provides a deeper understanding of complex social phenomena. Through in-depth interviews, focus groups, and observation, researchers can gather detailed information about participants’ experiences and perspectives that may be missed by other research methods.
• Flexibility : Qualitative research is a flexible approach that allows researchers to adapt their methods to the research question and context. Researchers can adjust their research methods in real-time to gather more information or explore unexpected findings.
• Contextual understanding: Qualitative research is well-suited to exploring the social and cultural context in which individuals or groups are situated. Researchers can gather information about cultural norms, social structures, and historical events that may influence participants’ experiences and perspectives.
• Participant perspective : Qualitative research prioritizes the perspective of participants, allowing researchers to explore subjective experiences and understand the meanings that participants attach to their experiences.
• Theory development: Qualitative research can contribute to the development of new theories and insights about complex social phenomena. By gathering rich, detailed data and using inductive data analysis, researchers can develop new theories and explanations that may challenge existing understandings.
• Validity : Qualitative research can offer high validity by using multiple data collection methods, purposive and diverse sampling, and researcher reflexivity. This can help ensure that findings are credible and trustworthy.

Limitations of Qualitative Research

Qualitative research also has some limitations, including:

• Subjectivity : Qualitative research relies on the subjective interpretation of researchers, which can introduce bias into the research process. The researcher’s perspective, beliefs, and experiences can influence the way data is collected, analyzed, and interpreted.
• Limited generalizability: Qualitative research typically involves small, purposive samples that may not be representative of larger populations. This limits the generalizability of findings to other contexts or populations.
• Time-consuming: Qualitative research can be a time-consuming process, requiring significant resources for data collection, analysis, and interpretation.
• Resource-intensive: Qualitative research may require more resources than other research methods, including specialized training for researchers, specialized software for data analysis, and transcription services.
• Limited reliability: Qualitative research may be less reliable than quantitative research, as it relies on the subjective interpretation of researchers. This can make it difficult to replicate findings or compare results across different studies.
• Ethics and confidentiality: Qualitative research involves collecting sensitive information from participants, which raises ethical concerns about confidentiality and informed consent. Researchers must take care to protect the privacy and confidentiality of participants and obtain informed consent.

7 Types of Qualitative Research + 6 Types of Qualitative Methods of Research

Do you want to learn about the types of qualitative research and some examples of methodologies?

Qualitative studies are vital to the market research process. They provide an understanding of the reasons and motivations behind consumer decisions. You can use this information to improve your marketing and increase sales.

What does that mean for your business?

If you have a product that isn’t selling as well as you expected, qualitative research can help you understand why. Or, if you’re launching a new marketing campaign, qualitative studies can help you create ads that will entice your target audience.

If you’re new to this kind of market research, you’re in the right place.

In this guide, you’ll learn the basics of qualitative market research. We’ll also share how your business can use qualitative data to better appeal to your customers.

What is Qualitative Research?

Why use qualitative research, 7 types of qualitative research, 6 types of qualitative methods of research.

• Ideas for Analyzing Qualitative Data

Qualitative research is any research that provides subjective, non-numerical information. It focuses on people: their experiences, beliefs, and behaviors. It’s generally conducted using observation or unstructured questioning.

Qualitative research is used across many fields and industries, including sales, marketing, health care, education, and social sciences.

Qualitative vs. Quantitative Research

You likely hear the term “qualitative” used in contrast with “quantitative.”

Quantitative research generates specific numerical data. Its goal is to quantify and generalize the results of a study through numbers, percentages, and statistics. Quantitative research seeks to answer the what , where , when, and who of decision-making.

Qualitative market research, on the other hand, provides insights into the deeper motives behind consumer purchases. Qualitative research answers the why and how .

Why should your business use qualitative research as opposed to quantitative research?

Well, first of all, you should not use qualitative market research instead of quantitative. The 2 are complementary to each other.

Qualitative research on its own is not conclusive. However, you can use it to:

• Explain quantitative research results.
• Conduct market research when traditional surveys are unavailable. For instance, when your topic involves sensitive or complex questions.
• Conduct market research when more structured research is not possible.

Let’s look at an example of combining quantitative and qualitative research.

For instance, we’ll say that your business wants to conduct research to improve your website.

Quantitative research would give you information such as:

• The number of website visitors
• The length of time users stay on each page
• The number of leads generated from each email signup form
• More quantitative data, such as online shopping statistics and conversion rates

This information is all important data about user behavior. But it doesn’t give you the why behind this behavior.

Qualitative research fills in the rest of the picture with information such as:

• Which parts of your website users find difficult to use
• Whether users find your lightbox popups to be intrusive
• Which special offers and coupon codes shoppers find exciting
• More subjective information about how users view the style, relevance, and usability of your site

A complete website study should include both quantitative and qualitative research. Then, you can improve your website based both on hard numbers and users’ experiences and opinions.

Qualitative market research collects subjective feedback and observations from consumers and users. However, as with most data collection, it’s much more complicated in practice.

Experts divide qualitative research into 7 main types. These are also sometimes called types of qualitative research designs.

Below, we’ll quickly explain the basics of each qualitative research approach before diving into qualitative research methods you can use for your market research.

Don’t feel like you have to memorize and fully understand all of these approaches. However, reviewing them will give you a good introduction to the field of qualitative research.

1. Phenomenology

Phenomenological research is based on the root word “phenomena.” It seeks to discover how individual people view specific experiences. Phenomenology focuses on lived experiences and individuality instead of generalizations about larger groups.

2. Ethnography

In the ethnography approach, researchers immerse themselves in a specific culture to gain qualitative data through observation and interaction. Ethnographic research provides more in-depth and nuanced information than, say, questionnaires or interviews. This approach also provides data about specific demographics.

3. Grounded Theory

The term “grounded theory” essentially describes the order in which researchers develop a theory.

In most other types of qualitative research, researchers start with a hypothesis and then conduct a study to test that hypothesis. However, researchers using grounded theory begin with qualitative data, such as interviews and observations, and then analyze it to develop a theory. This approach is helpful when you have no working theory for why consumers behave in a certain way.

4. Case Study

Case studies are in-depth examinations of a business, process, product, person, or group of people. They also often include quantitative research, but they become qualitative when they focus on the reasons behind that data and the participants’ individual experiences.

For instance, in our case study of AdamEnfroy.com , we present subjective feedback in addition to quantitative data:

See more examples of OptinMonster’s case study research.

5. Historical Research

The historical approach to research is reasonably self-explanatory. Researchers analyze data from the past to form expectations about the present and future. In qualitative market research, this might mean analyzing consumer feedback from throughout the history of your company or industry.

6. Narrative Research

The narrative approach seeks to tell a story about people’s experiences. Researchers conduct interviews and collect observations over a period of time. Then, they use this information to develop a narrative about the experiences of an individual or small group of people.

7. Action Research

Action research aims to investigate and solve a specific, immediate problem. This type of research is cyclical. Researchers apply an action, analyze the data, draw conclusions, and start again.

Now that you have an overview of the different types of qualitative research, we’ll explore types of qualitative methods of research along with some practical examples.

The approaches above are fairly abstract. Now, we’ll share some concrete qualitative methods to collect data for your business. Even beginners and small businesses can use these methodologies.

Here are some of the most common types of qualitative research methods to give you greater insight into your customers. Next time that you are ready to launch a new product or start a new marketing campaign, try out one or more of these methods. You’ll get valuable feedback that will help you succeed.

1. In-Depth Interviews Let You Dig Deep

In-depth interviews (IDIs) are a great way to get detailed consumer feedback. An IDI can be conducted over the phone, in person, or via webcam, using services like Skype or Zoom.

Webcam interviews have become the most common qualitative research method. 34% of researchers report regularly conducting webcam IDIs as 1 of their top 3 data collection methods.

Regardless of your interview method, your IDIs should focus on your ideal user or an existing customer. You ask each person a series of research questions and follow-ups to learn what motivates them to buy a product like yours.

For qualitative research, you should always ask open-ended questions. Avoid simple yes/no questions that provide only quantitative data.

You should go into the interview with some questions prepared, but you shouldn’t stick to a script. If the participant says something interesting, ask follow-up questions that dig deeper.

Here are a few initial questions you could ask:

• What frustrates you about [your topic]?
• If I had a magic wand and could give you the perfect product, what would it look like?
• Have you bought [your type of product] before? If so, what motivated you to buy it?

IDIs provide detailed information about individuals. Therefore, they are especially common in the phenomenology and narrative types of qualitative research.

2. Focus Groups Allow for the Exchange of Ideas

Like IDIs, focus groups can be face-to-face or online. These groups usually involve sample sizes of 6-10 people. They provide a safe and comfortable environment for your users to talk about their thoughts and feelings surrounding your product.

The advantage of in-person focus groups is that you observe the consumer’s verbal and non-verbal reaction to your product or advertising. Group members can also bounce off each other’s thoughts and ideas, which means you’ll get even greater insights.

You can use focus groups to:

• Test a new product or website
• Explore the general concept for your product
• Evaluate your advertising copy and imagery
• Explore new packaging ideas

Online focus groups are similar to in-person ones. They’re more cost-efficient, allow you to include more people, and are less time-consuming to organize. Now that more people are comfortable with Zoom and Skype, online focus groups are more accessible than ever before.

You can also use social media to your advantage. Create a community of people interested in your topic and use it to foster a conversation. Then, observe the dialogue. You’ll gain a lot of interesting insights!

3. Shopping Observations, or “Shop-Alongs,” Give Real-Time Insight

An in-person observation of shopping behavior lets you watch the consumer react to your products in-store. With a shop-along, you get to see consumers’ real-life shopping behavior. Because you see immediate reactions, this method provides different insight than a written survey.

These qualitative studies highlight problems with shelf displays, clutter, or out-of-stock products. You may also interact with consumers to get deeper insights during the shopping process. You can get real-time feedback on package design, for example.

4. In-Home Videos Show Realistic Product Use

In-home videos allow you to observe how users interact with your product in real life, in their own homes.

This research method’s advantage is the setting of the participant observation. You can see your user’s behavior in a natural, comfortable environment. You’ll get a more realistic view of how people use your product.

5. Lifestyle Immersion Lets You Hear Real-World Dialogue

Lifestyle immersion is when you attend an event, such as a party or a family gathering. This research method gives you an uninterrupted view of users’ attitudes and behaviors. Immersion is another excellent way to get candid insight in a comfortable, familiar setting.

During these activities, observe your users having a dialogue with their friends. Listen to these real-world conversations to learn about consumers’ desires, frustrations, and motivations.

6. Journal or Diary Studies for Honest Feedback

Have your user or potential customer keep a journal or a diary to document their experience with your topic or product. Users may be more likely to be completely honest when they’re not face-to-face with an interviewer or moderator.

Journals can be handwritten or digital. Either way, it will capture your user’s voice, which is extremely valuable for optimizing your marketing copy.

3 Tips for Qualitative Data Analysis (to Help You Understand Your Customers)

Using the methods and types of qualitative research discussed above, you can gather excellent information about consumers’ opinions, experiences, and behaviors. The next step is to analyze your data.

Since qualitative data is unstructured, it can be tricky to draw conclusions, let alone present your findings. While qualitative data is not conclusive in and of itself, here are a few tips for analyzing qualitative research data.

1. Summarize the Key Points

For interviews and focus groups, have the moderator write up some key points from the discussion. For example: “Common concerns among participants about our pizza were cheese overuse, greasiness, and bland sauce.”

Here is an example of a qualitative summary from a market research project for Pizza Hut Pakistan

2. Code Responses

Coding is the process of organizing and labeling your qualitative data into categories. You can “code” your unstructured data into labels you can summarize with tables or charts.

For example, a researcher might have asked the open-ended question, “How often do you wear a watch?”

Every respondent’s answer would likely be a little different. But you could code them in categories such as:

• Once in a while

This process gives you coded data sets to analyze and report.

3. Create a Word Cloud

Create a “word cloud” out of the keywords used by consumers. Put your field notes into a word cloud generator like WordClouds.com . In your cloud, the words that research participants used most often will be the largest. You’ll be able to spot the most prominent words easily.

Use Qualitative Research to Improve Marketing and Sales

You can use these qualitative research types, methods, and analysis strategies to understand your users and customers. Qualitative data collection will help you improve your product development and marketing strategy, leading to more sales and revenue.

If online surveys are part of your research process, check out our survey best practices .

Once you clearly understand your customers, apply what you’ve learned to your email marketing strategy . Using in-depth qualitative data, you’ll generate more leads and sales than ever before.

SHARE THE ARTICLE ON

Qualitative market research help businesses understand customers’ needs, identify market potential, uncover ideas for product launch/improvement, or understand how the product fits the target customer’s lifestyle. 

Any business of any type or size can benefit from qualitative research as it helps you find out how the target market feels about your product and uncover how you can improve it to increase sales. 

In this article, we’ll dive into qualitative research methods, how to conduct them, how to use them for market research, and more.

What is qualitative market research?

In simple terms, qualitative research can be defined as a method used for market research that aims at obtaining data with open-ended questions and conversations with the target consumers. 

This method helps establish not only “what” consumers think but also “how” they come to that opinion and “why” they think so. 

For instance, if you find out that more men are visiting your online garment shop than women, it is just a systematic observation. Qualitative market research will help you understand why women do not visit the store. 

You can gain this information by conducting an in-depth interview of potential women who could become customers, i.e., women who shop online regularly. In this way, qualitative research focuses on understanding a query or problem statement in a humanistic or idealistic approach.

• Qualitative research methods are used to understand the beliefs, experiences, attitudes, and behaviors of people. 
• It also helps in understanding the interactions people have with others who are similar to them.  
• Qualitative research is increasingly becoming popular because it gives a voice to the participants. 
• It gives us valuable insights into each individual and their feedback can prove to be valuable and enriching.  

What is the difference between qualitative and quantitative market research?

We have described what qualitative market research is, but let’s also see how it differs from quantitative. 

Quantitative Vs Qualitative market research: 

Quantitative research gathers numerical data that helps you test and draw conclusions regarding your research. The data helps you generate conclusive results. 

• It helps answer the “what” people think. 
• You can use it to confirm a hypothesis. 
• You can collect quantitative data via surveys , experiments, and observations.  

Qualitative research helps you gather non-numerical data that digs deeper to understand customer behavior. 

• It helps answer “why,” people think the way they do & “how” they make decisions. 
• You can use it to understand concepts. 
• You can gather qualitative data via interviews, ethnography, focus groups, case studies, and observation. 

You can leverage a market research tool to conduct research of your choice using multiple channels and gather integrated data.

5 qualitative market research methods

Qualitative research methods have originated from social and behavioral sciences. There are five common methods that researchers and marketers use to collect qualitative research data. 

These five methods are based on how you can collect data from the target audience. So, let’s discuss these five data collection methods. 

1. Interview  

Interviewing the target audience is one of the most common practices in qualitative market research. You can carry out an interview either face-to-face, on phone , or online with one respondent at a time. This is a conversational method of gathering information and allows the researcher to get a detailed response from the respondent.

The advantage of the interview method is that it gives one an opportunity to gather detailed and precise information about people’s beliefs, motivations, and experiences.  

If the researcher has experience in asking relevant and correct questions, it can help them collect meaningful data. These interviews usually last up to an hour or two, depending on how detailed and specific the researcher wants the data to be.  

Interviews can be structured, semi-structured, or unstructured. Semi-structured interviews are most commonly used because they give researchers an outline of what topics and areas to cover. Also permitting them to tap into any area relevant to the participant’s experiences.

2. Ethnography

Ethnographic research includes direct observation of the concerned group you want to study. This qualitative market research involves studying video recordings of the interactions between customers and products as they indulge in the purchased product in real life. 

Ethnographic researchers can observe their clients or participants of the research from anywhere, including the individual’s workplace, their familial environment, or when the individual is spending time with their peers.

Researchers fully immerse themselves into the lives of the customers. They observe and listen to the customers in their natural settings in a nondirected way. The goal, here, is to see people’s behaviors as they occur and on their terms, not our interpretation of those terms. 

This observational method enlightens researchers about the context in which consumers are using the products they are analyzing and the meaningful contribution of the product in their lives.  

3. Focus Groups

Another most commonly used method in qualitative market research is the focus group. In this method, the researcher gathers a limited number of consumers from the target market to create a focus group. 

The main aim of this focus group is to answer questions relating to the “why” “what” and “how” of behaviors. 

In a focus group, a trained moderator usually leads a discussion lasting about 30-90 minutes that is designed to gather useful information. The moderator’s main task is to hear the responses and probe respondents for any other specifications required while answering the questions.

Focus groups can now be sent an online survey on their preferred devices and their feedback can be collected through that. However, a disadvantage of focus groups is that they are time-consuming and costly. 

This method is usually recommended when the market is launching a new product and needs in-depth insight from the target audience’s perspective.

4. Case Studies

Case studies have evolved to become a valuable method for qualitative market research . It is used for explaining a case of an organization or an entity. This is one of the simplest ways of conducting research because it involves an exhaustive understanding of the data collected and the interpretation of the same.

5. Observation

Observation can be systematic or naturalistic. Qualitative observation of respondents’ answers or their behaviors in particular settings can yield enriching insights. 

The research observes the customer/consumer from a distance to see how they interact with an actual product. Often also called “shop-alongs”, this method reduces the possibility of a customer forgetting their shopping experience and providing false feedback at a later stage.

Methods to analyze qualitative market research data

There are different methods that are used to analyze qualitative market research data. The most commonly used method is the thematic analysis and text analysis.

Text analysis: 

In text analysis , researchers analyze the qualitative data collected directly from the audience and decode the sentiment and meaning behind the feedback. The analysis method helps identify a pattern/trend and make sense of the sentiment associated with the words used by the audience. 

Thematic analysis:

In thematic analysis , researchers find out the major themes or patterns in the respondents’ answers that are repeated several times. 

This kind of analysis helps researchers understand the themes that are important in the respondents’ life and the experiences that matter the most to them. They can then understand how the product they are aiming to improve or launch can affect these major themes in the lives of the respondents.  

Other qualitative analysis methods include content analysis, discourse analysis, and grounded theory. These methods differ in difficulty levels of conducting the analysis, and the steps to be followed while analyzing data.

What are the uses of qualitative market research?

Qualitative data helps you uncover hidden data and make meaning of customers’ purchase behavior. You can use qualitative research in business to make important decisions. 

Qualitative market research helps you gather contextual and unbiased feedback. You can gather deeper insights from the target market to understand consumers’ feelings about your brand and evaluate the brand-customer relationship.  

It provides you with hard facts on where you stand and helps you benchmark your performance.

2. Consumer behavior insights: 

You can use qualitative data to create an in-depth buyer/consumer persona. The customer behavior survey helps brands understand the needs, demands, and wants of the customers which helps them better market the product. 

3. Market/business opportunities: 

Explore new markets for business expansion by gathering qualitative insights. Leverage market research surveys to understand business trends, key competition, potential, or an ideal location for new opportunities. 

4. Product research: 

Be it a product upgrade or a new product concept , market research will help you understand if the target consumers will accept the product. Gather opinions and suggestions from consumers on various aspects of the product to create

How to conduct qualitative market research?

We have discussed the methods of data collection and uses of qualitative research so now let’s look at the steps to conduct qualitative market research. 

1. Determine the objective for conducting research: 

The research you want to conduct must have the desired outcome which explains what you want to achieve with this research. Determining the objective helps you map the research process and keep it aligned with the ultimate goal. 

2. Decide what methodology to use:

You can conduct qualitative research in many ways. We have explained five common methods – interview, ethnography, focus group, case study, and observation – above. 

3. Sample respondents: 

It’s not practical to gather responses from the entire target audience . Creating a sample audience enables you to gather relevant data that represents the target audience. 

It’s important to note a large sample size, gives you more accurate responses. There are three sampling methods – purpose, quota, and snowball sampling. 

You can also leverage a market research panel, like Voxco Audience , to create an ideal respondent panel for your research. A research panel gives you access to verified respondents willing to participate in research.

4. Design your survey: 

The questions you ask play an important role in the type of responses you gather. Personalize the survey, and write relevant and meaningful questions to engage the audience. 

5. Determine the data collection channels:

You can gather customer data online, offline, or by phone. For example, you can conduct a phone interview, a face-to-face interview, or a mobile-offline interview. Depending on the nature of the research, location, and the research topic, you can use a channel that will bring the most responses. 

6. Analyze the gathered data: 

Data analysis helps you make sense of your customer’s feedback. It helps you convert the data into actionable insights so you can make strategic business decisions. We have explained the analysis methods used for qualitative market research data above. 

7. Report the findings:

Share the findings with stakeholders, colleagues, executives, and everyone else in a way that is easy to understand. Use charts and graphs to give context to the findings instead of handing over long paragraphs. 

This sums up the seven steps to conducting qualitative research. Let’s look at some of its benefits.

Benefits of qualitative market research

Qualitative research is often used because it preserves the voice and perspectives of the respondents which are usually converted into numerics in quantitative research. The advantages of qualitative research are listed below:

• The process of data collection and analysis is flexible and conversational in qualitative research; they are not rigidly defined and do not have to be systematically planned or decided beforehand.
• Qualitative research takes place in a naturalistic environment and provides insight into how individuals behave in natural settings.
• Since qualitative market research uses open-ended questions when collecting data, they offer a huge deal of new information that can be uncovered and studied by the researcher.
• Qualitative research is recommended when studying the launch of a new product in the market, developing a new product in the market, understanding the strength and weaknesses of the product in the market, and exploring the marke t in terms of consumer behavior, demographics, perception of the brand and product under study.

Be it a start-up or an established company, qualitative market research helps you understand customers’ motivation, feelings, and perceptions of your products and services. This research method enables you to learn why consumers make certain decisions and use the feedback to build your marketing and sales strategies. 

FAQs on qualitative market research

Qualitative market research helps you gather data that explains why customers make certain purchase decision. It enables you to understand customers’ feelings, values, and thoughts about your products or services. 

The four types of qualitative research are: 

• Focus group

The 8 types of market research: definitions, uses and examples.

13 min read What are the different types of market research that can help you stay ahead of the curve with your marketing strategy? Understand how to use each type, and what the advantages and disadvantages are.

Market research (also called marketing research) is the action or activity of gathering information about market needs and preferences. This helps companies understand their target market — how the audience feels and behaves.

There are 8 types of market research, each with their own methods and tools:

• Primary research
• Secondary research
• Qualitative research
• Quantitative research
• Branding research
• Customer research
• Competitor research
• Product research

Let’s start our list by exploring primary and secondary research first.

Free eBook: How to rethink and reinvent market research

1. Primary research

Primary research is research that you collect yourself but going directly to the target market through a range of methods. Because it is data you create, you own the data set.

Two types of results — exploratory information (determines the nature of a problem that hasn’t yet been clearly defined) and conclusive information (carried out to solve a problem that exploratory research identified) — from participants are collected as raw data and then analyzed to gather insights from trends and comparisons.

This method is good for getting the views of a lot of people at one time, especially when time is short, but it comes with its own management issues. The interviewer must prepare a way to gather answers and record these, while engaging in conversation with many people.

Participants may be affected by the group setting, either from acquiescence bias (the desire to say yes to please the interviewer), dominance bias (stronger participants can alter the results from less dominant participants) or researcher bias (where the research leads or impacts the participant responses indirectly).

This provides a structured setting where the interviewer can listen to what’s being said and investigate further into an answer. The interviewer can also pick up on non-verbal cues from body language can help the interview understand where to deep-dive and broaden their understanding.

However, some of the same biases (acquiescence and researcher) still exit in this format. The method is time consuming to do the interviews and collect the data afterwards.

A survey is an excellent method for carrying out primary research as participants do need to be physically present with the interviewer to carry it out. The survey can be completed anywhere there is an internet connection, meaning there is flexibility for the participants to use different devices and for interviewers to contact participants in different geographical time-zones.Preparation is key, however, as the researchers must segment the market and create a list of participants to send the survey to. Hiring a panel or using existing marketing lists can help with this.

2. Secondary research

Secondary research is the use of data that has previously been collected, analysed and published (and therefore you do not own this data). An example of this for market research is:

Most information is freely available, so there are less costs associated with this kind of secondary research over primary research methods.

Secondary research can often be the preparation for primary research activities, providing a knowledge base. The information gathered may not provide the specific information to explain the results, which is where primary market research would be used to enhance understanding.

There is also a logistics planning need for a recording solution that can handle large datasets, since manual management of the volumes of information can be tricky.

Both primary and secondary research have its advantages and disadvantages, as we’ve seen, but they are best used when paired together. Combined, the data can give you the confidence to act knowing that any hypothesis you have is backed up.

The next market research types can be defined as qualitative and quantitative research types:

3. Qualitative research

Qualitative market research is the collection of primary or secondary data that is non-numerical in nature, and therefore hard to measure.

Researchers collect this market research type because it can add more depth to the data.

This kind of market research is used to summarise and infer, rather than pin-points an exact truth held by a target market. For example, qualitative market research can be done to find out a new target market’s reaction to a new product to translate the reaction into a clear explanation for the company.

4. Quantitative research

Quantitative research is the collection of primary or secondary data that is numerical in nature, and so can be collected more easily.

Researchers collect this market research type because it can provide historical benchmarking, based on facts and figures evidence.

There are a number of ways to collect this data — polls, surveys, desk research, web statistics, financial records — which can be exploratory in nature without a lot of depth at this stage.

Quantitative market research can create the foundation of knowledge needed by researchers to investigate hypotheses further through qualitative market research.

The next four variations of market research are specific to topics areas, that bring about specific information.:

5. Branding research

Branding market research assists a company to create, manage and maintain the company brand. This can relate to the tone, branding, images, values or identity of the company.

Research can be carried out through interviews, focus groups or surveys. For example, brand awareness surveys will ask your participants whether the brand is known to them and whether it is something they would be interested in buying.

Additional areas for brand research is also around brand loyalty, brand perception , brand positioning , brand value and brand identity .

The aim of research will be to understand how to know if:

• Your brand is performing in relation to other competitors
• There are areas to improve your brand activities
• There are positives to showcase to enhance your brand’s image

6. Customer research

Customer market research looks at the key influences on your target customers and how your company can make changes to encourage sales.

The aim of this research is to know your customer inside out, and continuously learn about how they interact with the company. Some themes covered by this include:

• Customer satisfaction – Exploring what keeps customers happy, as higher customer satisfaction is more likely to lead to increased customer retention.
• Customer loyalty – This looks at what experiences have happened to lead to greater customer loyalty across the customer lifecycle.
• Customer segmentation research – Discovering who the customers are, what their behaviour and preferences are and their shared characteristics.

Relevant desk research may look at historical purchase records, customer journey mapping , customer segmentation, demographics and persona templates.

Primary research, such as NPS and customer satisfaction surveys , or customer satisfaction interviews at the end of customer support calls, can also give more details.

7. Competitor research

Competitor market research is about knowing who your competition is and understanding their strengths and weaknesses, in comparison to your organization. It can also be about your competitive offering in the market, or how to approach a new market.

The aim of this research is to find ways to make your organization stand out and future planning through horizon scanning and listening to customer preferences.

For example, for competitive analysis, researchers would create a SWOT for your business and your competitors, to see how your business compares.

Primary research could interview customers about their buying preferences, while secondary sources would look at competitor’s market dominance, sales, structure and so on. With this thorough analysis, you can understand where you can change to be more competitive, and look for ideas that make you stand out.

8. Product research

Product market research is a key way to make sure your products and services are fit for launching in the market, and are performing as well as they can.

The aim of this research is to see how your product is perceived by customers, if they are providing value and working correctly. Ideas can also be formed about upgrades and future product development.

There are a number of avenues within product research:

• Product branding – Does the product brand and design attract customers in the intended way?
• Product feature testing – this can happen at various stages of development with target markets (in early development, between versions, before product launch, etc.) to check if there are positive reaction to new or improved features
• Product design thinking – what solutions would solve your customers’ current or future problems?
• Product marketing – Do the marketing messages help your product’s memorability and saleability, or can they be improved?

Primary research methods have a clear advantage in this kind of market research: Surveys can ask for rankings on the popularity or usefulness of features or conduct conjoint analysis, while in-person observation interviews (where the participant can handle a product) can be particularly useful in seeing what customers do with the product in real time.

How to use market research types in your company

In a good marketing strategy, it’s preferable to have a mixture of data across:

• Qualitative and quantitative research
• Primary and secondary research
• Your specific topic area or area of focus

With these three components, you can make sure your market strategy gives you a complete picture of your market’s operational data and experience data , — what your market does and why .

Economical experience data (O data)

This type of experience data is quantitative in nature (including operations, featuring sales data, finance data and HR data ). As it can be quantified into numerical values, it can be measured over and over, providing datasets.

There is the opportunity to use a data-driven approach to understanding the results and making predictions based on historical trends.

This sort of data can be measured more easily than emotions and feelings. But it can only tell you about past activities and what happened. It can’t tell you what will happen in the future and why things will happen — this is where X data comes in.

Emotional experience data (X data)

This type of experience data seeks to find reasons to explain emotional decisions and how brands ‘sit’ in people’s minds. In this way, this data is qualitative in nature.

Companies that have X data have a ‘mental advantage’ over other companies,  as they are able to understand the perceptions of the customer, their needs and values.

When you have tangible insights on the audience’s needs, you can then take steps to meet those needs and solve problems. This mitigates the risk of an experience gap – which is what your audience expects you deliver versus what you actually deliver.

What are your customers’ needs? How does your product compare to the competition? What are the emerging trends and opportunities in your industry? If these questions keep you up at night, it’s time to conduct market research.

Market research plays a pivotal role in your ability to stay competitive and relevant, helping you anticipate shifts in consumer behavior and industry dynamics. It involves gathering these insights using a wide range of techniques, from surveys and interviews to data analysis and observational studies.

In this guide, we’ll explore why market research is crucial, the various types of market research, the methods used in data collection, and how to effectively conduct market research to drive informed decision-making and success.

What is market research?

Market research is the systematic process of gathering, analyzing and interpreting information about a specific market or industry. The purpose of market research is to offer valuable insight into the preferences and behaviors of your target audience, and anticipate shifts in market trends and the competitive landscape. This information helps you make data-driven decisions, develop effective strategies for your business, and maximize your chances of long-term growth.

Why is market research important? 

By understanding the significance of market research, you can make sure you’re asking the right questions and using the process to your advantage. Some of the benefits of market research include:

• Informed decision-making: Market research provides you with the data and insights you need to make smart decisions for your business. It helps you identify opportunities, assess risks and tailor your strategies to meet the demands of the market. Without market research, decisions are often based on assumptions or guesswork, leading to costly mistakes.
• Customer-centric approach: A cornerstone of market research involves developing a deep understanding of customer needs and preferences. This gives you valuable insights into your target audience, helping you develop products, services and marketing campaigns that resonate with your customers.
• Competitive advantage: By conducting market research, you’ll gain a competitive edge. You’ll be able to identify gaps in the market, analyze competitor strengths and weaknesses, and position your business strategically. This enables you to create unique value propositions, differentiate yourself from competitors, and seize opportunities that others may overlook.
• Risk mitigation: Market research helps you anticipate market shifts and potential challenges. By identifying threats early, you can proactively adjust their strategies to mitigate risks and respond effectively to changing circumstances. This proactive approach is particularly valuable in volatile industries.
• Resource optimization: Conducting market research allows organizations to allocate their time, money and resources more efficiently. It ensures that investments are made in areas with the highest potential return on investment, reducing wasted resources and improving overall business performance.
• Adaptation to market trends: Markets evolve rapidly, driven by technological advancements, cultural shifts and changing consumer attitudes. Market research ensures that you stay ahead of these trends and adapt your offerings accordingly so you can avoid becoming obsolete. 

As you can see, market research empowers businesses to make data-driven decisions, cater to customer needs, outperform competitors, mitigate risks, optimize resources and stay agile in a dynamic marketplace. These benefits make it a huge industry; the global market research services market is expected to grow from $76.37 billion in 2021 to $108.57 billion in 2026 . Now, let’s dig into the different types of market research that can help you achieve these benefits.

Types of market research 

• Qualitative research
• Quantitative research
• Exploratory research
• Descriptive research
• Causal research
• Cross-sectional research
• Longitudinal research

Despite its advantages, 23% of organizations don’t have a clear market research strategy. Part of developing a strategy involves choosing the right type of market research for your business goals. The most commonly used approaches include:

1. Qualitative research

Qualitative research focuses on understanding the underlying motivations, attitudes and perceptions of individuals or groups. It is typically conducted through techniques like in-depth interviews, focus groups and content analysis — methods we’ll discuss further in the sections below. Qualitative research provides rich, nuanced insights that can inform product development, marketing strategies and brand positioning.

2. Quantitative research

Quantitative research, in contrast to qualitative research, involves the collection and analysis of numerical data, often through surveys, experiments and structured questionnaires. This approach allows for statistical analysis and the measurement of trends, making it suitable for large-scale market studies and hypothesis testing. While it’s worthwhile using a mix of qualitative and quantitative research, most businesses prioritize the latter because it is scientific, measurable and easily replicated across different experiments.

3. Exploratory research

Whether you’re conducting qualitative or quantitative research or a mix of both, exploratory research is often the first step. Its primary goal is to help you understand a market or problem so you can gain insights and identify potential issues or opportunities. This type of market research is less structured and is typically conducted through open-ended interviews, focus groups or secondary data analysis. Exploratory research is valuable when entering new markets or exploring new product ideas.

4. Descriptive research

As its name implies, descriptive research seeks to describe a market, population or phenomenon in detail. It involves collecting and summarizing data to answer questions about audience demographics and behaviors, market size, and current trends. Surveys, observational studies and content analysis are common methods used in descriptive research. 

5. Causal research

Causal research aims to establish cause-and-effect relationships between variables. It investigates whether changes in one variable result in changes in another. Experimental designs, A/B testing and regression analysis are common causal research methods. This sheds light on how specific marketing strategies or product changes impact consumer behavior.

6. Cross-sectional research

Cross-sectional market research involves collecting data from a sample of the population at a single point in time. It is used to analyze differences, relationships or trends among various groups within a population. Cross-sectional studies are helpful for market segmentation, identifying target audiences and assessing market trends at a specific moment.

7. Longitudinal research

Longitudinal research, in contrast to cross-sectional research, collects data from the same subjects over an extended period. This allows for the analysis of trends, changes and developments over time. Longitudinal studies are useful for tracking long-term developments in consumer preferences, brand loyalty and market dynamics.

Each type of market research has its strengths and weaknesses, and the method you choose depends on your specific research goals and the depth of understanding you’re aiming to achieve. In the following sections, we’ll delve into primary and secondary research approaches and specific research methods.

Primary vs. secondary market research

Market research of all types can be broadly categorized into two main approaches: primary research and secondary research. By understanding the differences between these approaches, you can better determine the most appropriate research method for your specific goals.

Primary market research 

Primary research involves the collection of original data straight from the source. Typically, this involves communicating directly with your target audience — through surveys, interviews, focus groups and more — to gather information. Here are some key attributes of primary market research:

• Customized data: Primary research provides data that is tailored to your research needs. You design a custom research study and gather information specific to your goals.
• Up-to-date insights: Because primary research involves communicating with customers, the data you collect reflects the most current market conditions and consumer behaviors.
• Time-consuming and resource-intensive: Despite its advantages, primary research can be labor-intensive and costly, especially when dealing with large sample sizes or complex study designs. Whether you hire a market research consultant, agency or use an in-house team, primary research studies consume a large amount of resources and time.

Secondary market research 

Secondary research, on the other hand, involves analyzing data that has already been compiled by third-party sources, such as online research tools, databases, news sites, industry reports and academic studies.

Here are the main characteristics of secondary market research:

• Cost-effective: Secondary research is generally more cost-effective than primary research since it doesn’t require building a research plan from scratch. You and your team can look at databases, websites and publications on an ongoing basis, without needing to design a custom experiment or hire a consultant. 
• Leverages multiple sources: Data tools and software extract data from multiple places across the web, and then consolidate that information within a single platform. This means you’ll get a greater amount of data and a wider scope from secondary research.
• Quick to access: You can access a wide range of information rapidly — often in seconds — if you’re using online research tools and databases. Because of this, you can act on insights sooner, rather than taking the time to develop an experiment. 

So, when should you use primary vs. secondary research? In practice, many market research projects incorporate both primary and secondary research to take advantage of the strengths of each approach.

One rule of thumb is to focus on secondary research to obtain background information, market trends or industry benchmarks. It is especially valuable for conducting preliminary research, competitor analysis, or when time and budget constraints are tight. Then, if you still have knowledge gaps or need to answer specific questions unique to your business model, use primary research to create a custom experiment. 

Market research methods

• Surveys and questionnaires
• Focus groups
• Observational research
• Online research tools
• Experiments
• Content analysis
• Ethnographic research

How do primary and secondary research approaches translate into specific research methods? Let’s take a look at the different ways you can gather data: 

1. Surveys and questionnaires

Surveys and questionnaires are popular methods for collecting structured data from a large number of respondents. They involve a set of predetermined questions that participants answer. Surveys can be conducted through various channels, including online tools, telephone interviews and in-person or online questionnaires. They are useful for gathering quantitative data and assessing customer demographics, opinions, preferences and needs. On average, customer surveys have a 33% response rate , so keep that in mind as you consider your sample size.

2. Interviews

Interviews are in-depth conversations with individuals or groups to gather qualitative insights. They can be structured (with predefined questions) or unstructured (with open-ended discussions). Interviews are valuable for exploring complex topics, uncovering motivations and obtaining detailed feedback. 

3. Focus groups

The most common primary research methods are in-depth webcam interviews and focus groups. Focus groups are a small gathering of participants who discuss a specific topic or product under the guidance of a moderator. These discussions are valuable for primary market research because they reveal insights into consumer attitudes, perceptions and emotions. Focus groups are especially useful for idea generation, concept testing and understanding group dynamics within your target audience.

4. Observational research

Observational research involves observing and recording participant behavior in a natural setting. This method is particularly valuable when studying consumer behavior in physical spaces, such as retail stores or public places. In some types of observational research, participants are aware you’re watching them; in other cases, you discreetly watch consumers without their knowledge, as they use your product. Either way, observational research provides firsthand insights into how people interact with products or environments.

5. Online research tools

You and your team can do your own secondary market research using online tools. These tools include data prospecting platforms and databases, as well as online surveys, social media listening, web analytics and sentiment analysis platforms. They help you gather data from online sources, monitor industry trends, track competitors, understand consumer preferences and keep tabs on online behavior. We’ll talk more about choosing the right market research tools in the sections that follow.

6. Experiments

Market research experiments are controlled tests of variables to determine causal relationships. While experiments are often associated with scientific research, they are also used in market research to assess the impact of specific marketing strategies, product features, or pricing and packaging changes.

7. Content analysis

Content analysis involves the systematic examination of textual, visual or audio content to identify patterns, themes and trends. It’s commonly applied to customer reviews, social media posts and other forms of online content to analyze consumer opinions and sentiments.

8. Ethnographic research

Ethnographic research immerses researchers into the daily lives of consumers to understand their behavior and culture. This method is particularly valuable when studying niche markets or exploring the cultural context of consumer choices.

Now that you have gained insights into the various market research methods at your disposal, let’s delve into the practical aspects of how to conduct market research effectively. Here’s a quick step-by-step overview, from defining objectives to monitoring market shifts.

1. Set clear objectives

When you set clear and specific goals, you’re essentially creating a compass to guide your research questions and methodology. Start by precisely defining what you want to achieve. Are you launching a new product and want to understand its viability in the market? Are you evaluating customer satisfaction with a product redesign? 

Start by creating SMART goals — objectives that are specific, measurable, achievable, relevant and time-bound. Not only will this clarify your research focus from the outset, but it will also help you track progress and benchmark your success throughout the process. 

You should also consult with key stakeholders and team members to ensure alignment on your research objectives before diving into data collecting. This will help you gain diverse perspectives and insights that will shape your research approach.

2. Identify your target audience

Next, you’ll need to pinpoint your target audience to determine who should be included in your research. Begin by creating detailed buyer personas or stakeholder profiles. Consider demographic factors like age, gender, income and location, but also delve into psychographics, such as interests, values and pain points.

The more specific your target audience, the more accurate and actionable your research will be. Additionally, segment your audience if your research objectives involve studying different groups, such as current customers and potential leads.

If you already have existing customers, you can also hold conversations with them to better understand your target market. From there, you can refine your buyer personas and tailor your research methods accordingly.

3. Choose your research methods

Selecting the right research methods is crucial for gathering high-quality data. Start by considering the nature of your research objectives. If you’re exploring consumer preferences, surveys and interviews can provide valuable insights. For in-depth understanding, focus groups or observational research might be suitable. Consider using a mix of quantitative and qualitative methods to gain a well-rounded perspective. 

You’ll also need to consider your budget. Think about what you can realistically achieve using the time and resources available to you. If you have a fairly generous budget, you may want to try a mix of primary and secondary research approaches. If you’re doing market research for a startup , on the other hand, chances are your budget is somewhat limited. If that’s the case, try addressing your goals with secondary research tools before investing time and effort in a primary research study. 

4. Use the right market research tools

Whether you’re conducting primary or secondary research, you’ll need to choose the right tools. These can help you do anything from sending surveys to customers to monitoring trends and analyzing data. Here are some examples of popular market research tools:

• Market research software: Crunchbase is a platform that provides best-in-class company data, making it valuable for market research on growing companies and industries. You can use Crunchbase to access trusted, first-party funding data, revenue data, news and firmographics, enabling you to monitor industry trends and understand customer needs.

• Survey and questionnaire tools: SurveyMonkey is a widely used online survey platform that allows you to create, distribute and analyze surveys. Google Forms is a free tool that lets you create surveys and collect responses through Google Drive.
• Data analysis software: Microsoft Excel and Google Sheets are useful for conducting statistical analyses. SPSS is a powerful statistical analysis software used for data processing, analysis and reporting.
• Social listening tools: Brandwatch is a social listening and analytics platform that helps you monitor social media conversations, track sentiment and analyze trends. Mention is a media monitoring tool that allows you to track mentions of your brand, competitors and keywords across various online sources.
• Data visualization platforms: Tableau is a data visualization tool that helps you create interactive and shareable dashboards and reports. Power BI by Microsoft is a business analytics tool for creating interactive visualizations and reports.

5. Collect data

There’s an infinite amount of data you could be collecting using these tools, so you’ll need to be intentional about going after the data that aligns with your research goals. Implement your chosen research methods, whether it’s distributing surveys, conducting interviews or pulling from secondary research platforms. Pay close attention to data quality and accuracy, and stick to a standardized process to streamline data capture and reduce errors. 

6. Analyze data

Once data is collected, you’ll need to analyze it systematically. Use statistical software or analysis tools to identify patterns, trends and correlations. For qualitative data, employ thematic analysis to extract common themes and insights. Visualize your findings with charts, graphs and tables to make complex data more understandable.

If you’re not proficient in data analysis, consider outsourcing or collaborating with a data analyst who can assist in processing and interpreting your data accurately.

7. Interpret your findings

Interpreting your market research findings involves understanding what the data means in the context of your objectives. Are there significant trends that uncover the answers to your initial research questions? Consider the implications of your findings on your business strategy. It’s essential to move beyond raw data and extract actionable insights that inform decision-making.

Hold a cross-functional meeting or workshop with relevant team members to collectively interpret the findings. Different perspectives can lead to more comprehensive insights and innovative solutions.

8. Identify opportunities and challenges

Use your research findings to identify potential growth opportunities and challenges within your market. What segments of your audience are underserved or overlooked? Are there emerging trends you can capitalize on? Conversely, what obstacles or competitors could hinder your progress?

Lay out this information in a clear and organized way by conducting a SWOT analysis, which stands for strengths, weaknesses, opportunities and threats. Jot down notes for each of these areas to provide a structured overview of gaps and hurdles in the market.

9. Make informed business decisions

Market research is only valuable if it leads to informed decisions for your company. Based on your insights, devise actionable strategies and initiatives that align with your research objectives. Whether it’s refining your product, targeting new customer segments or adjusting pricing, ensure your decisions are rooted in the data.

At this point, it’s also crucial to keep your team aligned and accountable. Create an action plan that outlines specific steps, responsibilities and timelines for implementing the recommendations derived from your research. 

10. Monitor and adapt

Market research isn’t a one-time activity; it’s an ongoing process. Continuously monitor market conditions, customer behaviors and industry trends. Set up mechanisms to collect real-time data and feedback. As you gather new information, be prepared to adapt your strategies and tactics accordingly. Regularly revisiting your research ensures your business remains agile and reflects changing market dynamics and consumer preferences.

Online market research sources

As you go through the steps above, you’ll want to turn to trusted, reputable sources to gather your data. Here’s a list to get you started:

• Crunchbase: As mentioned above, Crunchbase is an online platform with an extensive dataset, allowing you to access in-depth insights on market trends, consumer behavior and competitive analysis. You can also customize your search options to tailor your research to specific industries, geographic regions or customer personas.

• Academic databases: Academic databases, such as ProQuest and JSTOR , are treasure troves of scholarly research papers, studies and academic journals. They offer in-depth analyses of various subjects, including market trends, consumer preferences and industry-specific insights. Researchers can access a wealth of peer-reviewed publications to gain a deeper understanding of their research topics.
• Government and NGO databases: Government agencies, nongovernmental organizations and other institutions frequently maintain databases containing valuable economic, demographic and industry-related data. These sources offer credible statistics and reports on a wide range of topics, making them essential for market researchers. Examples include the U.S. Census Bureau , the Bureau of Labor Statistics and the Pew Research Center .
• Industry reports: Industry reports and market studies are comprehensive documents prepared by research firms, industry associations and consulting companies. They provide in-depth insights into specific markets, including market size, trends, competitive analysis and consumer behavior. You can find this information by looking at relevant industry association databases; examples include the American Marketing Association and the National Retail Federation .
• Social media and online communities: Social media platforms like LinkedIn or Twitter (X) , forums such as Reddit and Quora , and review platforms such as G2 can provide real-time insights into consumer sentiment, opinions and trends. 

Market research examples

At this point, you have market research tools and data sources — but how do you act on the data you gather? Let’s go over some real-world examples that illustrate the practical application of market research across various industries. These examples showcase how market research can lead to smart decision-making and successful business decisions.

Example 1: Apple’s iPhone launch

Apple ’s iconic iPhone launch in 2007 serves as a prime example of market research driving product innovation in tech. Before the iPhone’s release, Apple conducted extensive market research to understand consumer preferences, pain points and unmet needs in the mobile phone industry. This research led to the development of a touchscreen smartphone with a user-friendly interface, addressing consumer demands for a more intuitive and versatile device. The result was a revolutionary product that disrupted the market and redefined the smartphone industry.

Example 2: McDonald’s global expansion

McDonald’s successful global expansion strategy demonstrates the importance of market research when expanding into new territories. Before entering a new market, McDonald’s conducts thorough research to understand local tastes, preferences and cultural nuances. This research informs menu customization, marketing strategies and store design. For instance, in India, McDonald’s offers a menu tailored to local preferences, including vegetarian options. This market-specific approach has enabled McDonald’s to adapt and thrive in diverse global markets.

Example 3: Organic and sustainable farming

The shift toward organic and sustainable farming practices in the food industry is driven by market research that indicates increased consumer demand for healthier and environmentally friendly food options. As a result, food producers and retailers invest in sustainable sourcing and organic product lines — such as with these sustainable seafood startups — to align with this shift in consumer values. 

The bottom line? Market research has multiple use cases and is a critical practice for any industry. Whether it’s launching groundbreaking products, entering new markets or responding to changing consumer preferences, you can use market research to shape successful strategies and outcomes.

This paper aims to provide an overview of the use and assessment of qualitative research methods in the health sciences. Qualitative research can be defined as the study of the nature of phenomena and is especially appropriate for answering questions of why something is (not) observed, assessing complex multi-component interventions, and focussing on intervention improvement. The most common methods of data collection are document study, (non-) participant observations, semi-structured interviews and focus groups. For data analysis, field-notes and audio-recordings are transcribed into protocols and transcripts, and coded using qualitative data management software. Criteria such as checklists, reflexivity, sampling strategies, piloting, co-coding, member-checking and stakeholder involvement can be used to enhance and assess the quality of the research conducted. Using qualitative in addition to quantitative designs will equip us with better tools to address a greater range of research problems, and to fill in blind spots in current neurological research and practice.

The aim of this paper is to provide an overview of qualitative research methods, including hands-on information on how they can be used, reported and assessed. This article is intended for beginning qualitative researchers in the health sciences as well as experienced quantitative researchers who wish to broaden their understanding of qualitative research.

What is qualitative research?

Qualitative research is defined as “the study of the nature of phenomena”, including “their quality, different manifestations, the context in which they appear or the perspectives from which they can be perceived” , but excluding “their range, frequency and place in an objectively determined chain of cause and effect” [ 1 ]. This formal definition can be complemented with a more pragmatic rule of thumb: qualitative research generally includes data in form of words rather than numbers [ 2 ].

Why conduct qualitative research?

Because some research questions cannot be answered using (only) quantitative methods. For example, one Australian study addressed the issue of why patients from Aboriginal communities often present late or not at all to specialist services offered by tertiary care hospitals. Using qualitative interviews with patients and staff, it found one of the most significant access barriers to be transportation problems, including some towns and communities simply not having a bus service to the hospital [ 3 ]. A quantitative study could have measured the number of patients over time or even looked at possible explanatory factors – but only those previously known or suspected to be of relevance. To discover reasons for observed patterns, especially the invisible or surprising ones, qualitative designs are needed.

While qualitative research is common in other fields, it is still relatively underrepresented in health services research. The latter field is more traditionally rooted in the evidence-based-medicine paradigm, as seen in " research that involves testing the effectiveness of various strategies to achieve changes in clinical practice, preferably applying randomised controlled trial study designs (...) " [ 4 ]. This focus on quantitative research and specifically randomised controlled trials (RCT) is visible in the idea of a hierarchy of research evidence which assumes that some research designs are objectively better than others, and that choosing a "lesser" design is only acceptable when the better ones are not practically or ethically feasible [ 5 , 6 ]. Others, however, argue that an objective hierarchy does not exist, and that, instead, the research design and methods should be chosen to fit the specific research question at hand – "questions before methods" [ 2 , 7 – 9 ]. This means that even when an RCT is possible, some research problems require a different design that is better suited to addressing them. Arguing in JAMA, Berwick uses the example of rapid response teams in hospitals, which he describes as " a complex, multicomponent intervention – essentially a process of social change" susceptible to a range of different context factors including leadership or organisation history. According to him, "[in] such complex terrain, the RCT is an impoverished way to learn. Critics who use it as a truth standard in this context are incorrect" [ 8 ] . Instead of limiting oneself to RCTs, Berwick recommends embracing a wider range of methods , including qualitative ones, which for "these specific applications, (...) are not compromises in learning how to improve; they are superior" [ 8 ].

Research problems that can be approached particularly well using qualitative methods include assessing complex multi-component interventions or systems (of change), addressing questions beyond “what works”, towards “what works for whom when, how and why”, and focussing on intervention improvement rather than accreditation [ 7 , 9 – 12 ]. Using qualitative methods can also help shed light on the “softer” side of medical treatment. For example, while quantitative trials can measure the costs and benefits of neuro-oncological treatment in terms of survival rates or adverse effects, qualitative research can help provide a better understanding of patient or caregiver stress, visibility of illness or out-of-pocket expenses.

How to conduct qualitative research?

Given that qualitative research is characterised by flexibility, openness and responsivity to context, the steps of data collection and analysis are not as separate and consecutive as they tend to be in quantitative research [ 13 , 14 ]. As Fossey puts it : “sampling, data collection, analysis and interpretation are related to each other in a cyclical (iterative) manner, rather than following one after another in a stepwise approach” [ 15 ]. The researcher can make educated decisions with regard to the choice of method, how they are implemented, and to which and how many units they are applied [ 13 ]. As shown in Fig.  1 , this can involve several back-and-forth steps between data collection and analysis where new insights and experiences can lead to adaption and expansion of the original plan. Some insights may also necessitate a revision of the research question and/or the research design as a whole. The process ends when saturation is achieved, i.e. when no relevant new information can be found (see also below: sampling and saturation). For reasons of transparency, it is essential for all decisions as well as the underlying reasoning to be well-documented.

Iterative research process

While it is not always explicitly addressed, qualitative methods reflect a different underlying research paradigm than quantitative research (e.g. constructivism or interpretivism as opposed to positivism). The choice of methods can be based on the respective underlying substantive theory or theoretical framework used by the researcher [ 2 ].

Data collection

The methods of qualitative data collection most commonly used in health research are document study, observations, semi-structured interviews and focus groups [ 1 , 14 , 16 , 17 ].

Document study

Document study (also called document analysis) refers to the review by the researcher of written materials [ 14 ]. These can include personal and non-personal documents such as archives, annual reports, guidelines, policy documents, diaries or letters.

Observations

Observations are particularly useful to gain insights into a certain setting and actual behaviour – as opposed to reported behaviour or opinions [ 13 ]. Qualitative observations can be either participant or non-participant in nature. In participant observations, the observer is part of the observed setting, for example a nurse working in an intensive care unit [ 18 ]. In non-participant observations, the observer is “on the outside looking in”, i.e. present in but not part of the situation, trying not to influence the setting by their presence. Observations can be planned (e.g. for 3 h during the day or night shift) or ad hoc (e.g. as soon as a stroke patient arrives at the emergency room). During the observation, the observer takes notes on everything or certain pre-determined parts of what is happening around them, for example focusing on physician-patient interactions or communication between different professional groups. Written notes can be taken during or after the observations, depending on feasibility (which is usually lower during participant observations) and acceptability (e.g. when the observer is perceived to be judging the observed). Afterwards, these field notes are transcribed into observation protocols. If more than one observer was involved, field notes are taken independently, but notes can be consolidated into one protocol after discussions. Advantages of conducting observations include minimising the distance between the researcher and the researched, the potential discovery of topics that the researcher did not realise were relevant and gaining deeper insights into the real-world dimensions of the research problem at hand [ 18 ].

Semi-structured interviews

Hijmans & Kuyper describe qualitative interviews as “an exchange with an informal character, a conversation with a goal” [ 19 ]. Interviews are used to gain insights into a person’s subjective experiences, opinions and motivations – as opposed to facts or behaviours [ 13 ]. Interviews can be distinguished by the degree to which they are structured (i.e. a questionnaire), open (e.g. free conversation or autobiographical interviews) or semi-structured [ 2 , 13 ]. Semi-structured interviews are characterized by open-ended questions and the use of an interview guide (or topic guide/list) in which the broad areas of interest, sometimes including sub-questions, are defined [ 19 ]. The pre-defined topics in the interview guide can be derived from the literature, previous research or a preliminary method of data collection, e.g. document study or observations. The topic list is usually adapted and improved at the start of the data collection process as the interviewer learns more about the field [ 20 ]. Across interviews the focus on the different (blocks of) questions may differ and some questions may be skipped altogether (e.g. if the interviewee is not able or willing to answer the questions or for concerns about the total length of the interview) [ 20 ]. Qualitative interviews are usually not conducted in written format as it impedes on the interactive component of the method [ 20 ]. In comparison to written surveys, qualitative interviews have the advantage of being interactive and allowing for unexpected topics to emerge and to be taken up by the researcher. This can also help overcome a provider or researcher-centred bias often found in written surveys, which by nature, can only measure what is already known or expected to be of relevance to the researcher. Interviews can be audio- or video-taped; but sometimes it is only feasible or acceptable for the interviewer to take written notes [ 14 , 16 , 20 ].

Focus groups

Focus groups are group interviews to explore participants’ expertise and experiences, including explorations of how and why people behave in certain ways [ 1 ]. Focus groups usually consist of 6–8 people and are led by an experienced moderator following a topic guide or “script” [ 21 ]. They can involve an observer who takes note of the non-verbal aspects of the situation, possibly using an observation guide [ 21 ]. Depending on researchers’ and participants’ preferences, the discussions can be audio- or video-taped and transcribed afterwards [ 21 ]. Focus groups are useful for bringing together homogeneous (to a lesser extent heterogeneous) groups of participants with relevant expertise and experience on a given topic on which they can share detailed information [ 21 ]. Focus groups are a relatively easy, fast and inexpensive method to gain access to information on interactions in a given group, i.e. “the sharing and comparing” among participants [ 21 ]. Disadvantages include less control over the process and a lesser extent to which each individual may participate. Moreover, focus group moderators need experience, as do those tasked with the analysis of the resulting data. Focus groups can be less appropriate for discussing sensitive topics that participants might be reluctant to disclose in a group setting [ 13 ]. Moreover, attention must be paid to the emergence of “groupthink” as well as possible power dynamics within the group, e.g. when patients are awed or intimidated by health professionals.

Choosing the “right” method

As explained above, the school of thought underlying qualitative research assumes no objective hierarchy of evidence and methods. This means that each choice of single or combined methods has to be based on the research question that needs to be answered and a critical assessment with regard to whether or to what extent the chosen method can accomplish this – i.e. the “fit” between question and method [ 14 ]. It is necessary for these decisions to be documented when they are being made, and to be critically discussed when reporting methods and results.

Let us assume that our research aim is to examine the (clinical) processes around acute endovascular treatment (EVT), from the patient’s arrival at the emergency room to recanalization, with the aim to identify possible causes for delay and/or other causes for sub-optimal treatment outcome. As a first step, we could conduct a document study of the relevant standard operating procedures (SOPs) for this phase of care – are they up-to-date and in line with current guidelines? Do they contain any mistakes, irregularities or uncertainties that could cause delays or other problems? Regardless of the answers to these questions, the results have to be interpreted based on what they are: a written outline of what care processes in this hospital should look like. If we want to know what they actually look like in practice, we can conduct observations of the processes described in the SOPs. These results can (and should) be analysed in themselves, but also in comparison to the results of the document analysis, especially as regards relevant discrepancies. Do the SOPs outline specific tests for which no equipment can be observed or tasks to be performed by specialized nurses who are not present during the observation? It might also be possible that the written SOP is outdated, but the actual care provided is in line with current best practice. In order to find out why these discrepancies exist, it can be useful to conduct interviews. Are the physicians simply not aware of the SOPs (because their existence is limited to the hospital’s intranet) or do they actively disagree with them or does the infrastructure make it impossible to provide the care as described? Another rationale for adding interviews is that some situations (or all of their possible variations for different patient groups or the day, night or weekend shift) cannot practically or ethically be observed. In this case, it is possible to ask those involved to report on their actions – being aware that this is not the same as the actual observation. A senior physician’s or hospital manager’s description of certain situations might differ from a nurse’s or junior physician’s one, maybe because they intentionally misrepresent facts or maybe because different aspects of the process are visible or important to them. In some cases, it can also be relevant to consider to whom the interviewee is disclosing this information – someone they trust, someone they are otherwise not connected to, or someone they suspect or are aware of being in a potentially “dangerous” power relationship to them. Lastly, a focus group could be conducted with representatives of the relevant professional groups to explore how and why exactly they provide care around EVT. The discussion might reveal discrepancies (between SOPs and actual care or between different physicians) and motivations to the researchers as well as to the focus group members that they might not have been aware of themselves. For the focus group to deliver relevant information, attention has to be paid to its composition and conduct, for example, to make sure that all participants feel safe to disclose sensitive or potentially problematic information or that the discussion is not dominated by (senior) physicians only. The resulting combination of data collection methods is shown in Fig.  2 .

The combination of multiple data source as described for this example can be referred to as “triangulation”, in which multiple measurements are carried out from different angles to achieve a more comprehensive understanding of the phenomenon under study [ 22 , 23 ].

Data analysis

To analyse the data collected through observations, interviews and focus groups these need to be transcribed into protocols and transcripts (see Fig.  3 ). Interviews and focus groups can be transcribed verbatim , with or without annotations for behaviour (e.g. laughing, crying, pausing) and with or without phonetic transcription of dialects and filler words, depending on what is expected or known to be relevant for the analysis. In the next step, the protocols and transcripts are coded , that is, marked (or tagged, labelled) with one or more short descriptors of the content of a sentence or paragraph [ 2 , 15 , 23 ]. Jansen describes coding as “connecting the raw data with “theoretical” terms” [ 20 ]. In a more practical sense, coding makes raw data sortable. This makes it possible to extract and examine all segments describing, say, a tele-neurology consultation from multiple data sources (e.g. SOPs, emergency room observations, staff and patient interview). In a process of synthesis and abstraction, the codes are then grouped, summarised and/or categorised [ 15 , 20 ]. The end product of the coding or analysis process is a descriptive theory of the behavioural pattern under investigation [ 20 ]. The coding process is performed using qualitative data management software, the most common ones being InVivo, MaxQDA and Atlas.ti. It should be noted that these are data management tools which support the analysis performed by the researcher(s) [ 14 ].

How to report qualitative research?

Protocols of qualitative research can be published separately and in advance of the study results. However, the aim is not the same as in RCT protocols, i.e. to pre-define and set in stone the research questions and primary or secondary endpoints. Rather, it is a way to describe the research methods in detail, which might not be possible in the results paper given journals’ word limits. Qualitative research papers are usually longer than their quantitative counterparts to allow for deep understanding and so-called “thick description”. In the methods section, the focus is on transparency of the methods used, including why, how and by whom they were implemented in the specific study setting, so as to enable a discussion of whether and how this may have influenced data collection, analysis and interpretation. The results section usually starts with a paragraph outlining the main findings, followed by more detailed descriptions of, for example, the commonalities, discrepancies or exceptions per category [ 20 ]. Here it is important to support main findings by relevant quotations, which may add information, context, emphasis or real-life examples [ 20 , 23 ]. It is subject to debate in the field whether it is relevant to state the exact number or percentage of respondents supporting a certain statement (e.g. “Five interviewees expressed negative feelings towards XYZ”) [ 21 ].

How to combine qualitative with quantitative research?

Qualitative methods can be combined with other methods in multi- or mixed methods designs, which “[employ] two or more different methods [ …] within the same study or research program rather than confining the research to one single method” [ 24 ]. Reasons for combining methods can be diverse, including triangulation for corroboration of findings, complementarity for illustration and clarification of results, expansion to extend the breadth and range of the study, explanation of (unexpected) results generated with one method with the help of another, or offsetting the weakness of one method with the strength of another [ 1 , 17 , 24 – 26 ]. The resulting designs can be classified according to when, why and how the different quantitative and/or qualitative data strands are combined. The three most common types of mixed method designs are the convergent parallel design , the explanatory sequential design and the exploratory sequential design. The designs with examples are shown in Fig.  4 .

Three common mixed methods designs

In the convergent parallel design, a qualitative study is conducted in parallel to and independently of a quantitative study, and the results of both studies are compared and combined at the stage of interpretation of results. Using the above example of EVT provision, this could entail setting up a quantitative EVT registry to measure process times and patient outcomes in parallel to conducting the qualitative research outlined above, and then comparing results. Amongst other things, this would make it possible to assess whether interview respondents’ subjective impressions of patients receiving good care match modified Rankin Scores at follow-up, or whether observed delays in care provision are exceptions or the rule when compared to door-to-needle times as documented in the registry. In the explanatory sequential design, a quantitative study is carried out first, followed by a qualitative study to help explain the results from the quantitative study. This would be an appropriate design if the registry alone had revealed relevant delays in door-to-needle times and the qualitative study would be used to understand where and why these occurred, and how they could be improved. In the exploratory design, the qualitative study is carried out first and its results help informing and building the quantitative study in the next step [ 26 ]. If the qualitative study around EVT provision had shown a high level of dissatisfaction among the staff members involved, a quantitative questionnaire investigating staff satisfaction could be set up in the next step, informed by the qualitative study on which topics dissatisfaction had been expressed. Amongst other things, the questionnaire design would make it possible to widen the reach of the research to more respondents from different (types of) hospitals, regions, countries or settings, and to conduct sub-group analyses for different professional groups.

How to assess qualitative research?

A variety of assessment criteria and lists have been developed for qualitative research, ranging in their focus and comprehensiveness [ 14 , 17 , 27 ]. However, none of these has been elevated to the “gold standard” in the field. In the following, we therefore focus on a set of commonly used assessment criteria that, from a practical standpoint, a researcher can look for when assessing a qualitative research report or paper.

Assessors should check the authors’ use of and adherence to the relevant reporting checklists (e.g. Standards for Reporting Qualitative Research (SRQR)) to make sure all items that are relevant for this type of research are addressed [ 23 , 28 ]. Discussions of quantitative measures in addition to or instead of these qualitative measures can be a sign of lower quality of the research (paper). Providing and adhering to a checklist for qualitative research contributes to an important quality criterion for qualitative research, namely transparency [ 15 , 17 , 23 ].

Reflexivity

While methodological transparency and complete reporting is relevant for all types of research, some additional criteria must be taken into account for qualitative research. This includes what is called reflexivity, i.e. sensitivity to the relationship between the researcher and the researched, including how contact was established and maintained, or the background and experience of the researcher(s) involved in data collection and analysis. Depending on the research question and population to be researched this can be limited to professional experience, but it may also include gender, age or ethnicity [ 17 , 27 ]. These details are relevant because in qualitative research, as opposed to quantitative research, the researcher as a person cannot be isolated from the research process [ 23 ]. It may influence the conversation when an interviewed patient speaks to an interviewer who is a physician, or when an interviewee is asked to discuss a gynaecological procedure with a male interviewer, and therefore the reader must be made aware of these details [ 19 ].

Sampling and saturation

The aim of qualitative sampling is for all variants of the objects of observation that are deemed relevant for the study to be present in the sample “ to see the issue and its meanings from as many angles as possible” [ 1 , 16 , 19 , 20 , 27 ] , and to ensure “information-richness [ 15 ]. An iterative sampling approach is advised, in which data collection (e.g. five interviews) is followed by data analysis, followed by more data collection to find variants that are lacking in the current sample. This process continues until no new (relevant) information can be found and further sampling becomes redundant – which is called saturation [ 1 , 15 ] . In other words: qualitative data collection finds its end point not a priori , but when the research team determines that saturation has been reached [ 29 , 30 ].

This is also the reason why most qualitative studies use deliberate instead of random sampling strategies. This is generally referred to as “ purposive sampling” , in which researchers pre-define which types of participants or cases they need to include so as to cover all variations that are expected to be of relevance, based on the literature, previous experience or theory (i.e. theoretical sampling) [ 14 , 20 ]. Other types of purposive sampling include (but are not limited to) maximum variation sampling, critical case sampling or extreme or deviant case sampling [ 2 ]. In the above EVT example, a purposive sample could include all relevant professional groups and/or all relevant stakeholders (patients, relatives) and/or all relevant times of observation (day, night and weekend shift).

Assessors of qualitative research should check whether the considerations underlying the sampling strategy were sound and whether or how researchers tried to adapt and improve their strategies in stepwise or cyclical approaches between data collection and analysis to achieve saturation [ 14 ].

Good qualitative research is iterative in nature, i.e. it goes back and forth between data collection and analysis, revising and improving the approach where necessary. One example of this are pilot interviews, where different aspects of the interview (especially the interview guide, but also, for example, the site of the interview or whether the interview can be audio-recorded) are tested with a small number of respondents, evaluated and revised [ 19 ]. In doing so, the interviewer learns which wording or types of questions work best, or which is the best length of an interview with patients who have trouble concentrating for an extended time. Of course, the same reasoning applies to observations or focus groups which can also be piloted.

Ideally, coding should be performed by at least two researchers, especially at the beginning of the coding process when a common approach must be defined, including the establishment of a useful coding list (or tree), and when a common meaning of individual codes must be established [ 23 ]. An initial sub-set or all transcripts can be coded independently by the coders and then compared and consolidated after regular discussions in the research team. This is to make sure that codes are applied consistently to the research data.

Member checking

Member checking, also called respondent validation , refers to the practice of checking back with study respondents to see if the research is in line with their views [ 14 , 27 ]. This can happen after data collection or analysis or when first results are available [ 23 ]. For example, interviewees can be provided with (summaries of) their transcripts and asked whether they believe this to be a complete representation of their views or whether they would like to clarify or elaborate on their responses [ 17 ]. Respondents’ feedback on these issues then becomes part of the data collection and analysis [ 27 ].

Stakeholder involvement

In those niches where qualitative approaches have been able to evolve and grow, a new trend has seen the inclusion of patients and their representatives not only as study participants (i.e. “members”, see above) but as consultants to and active participants in the broader research process [ 31 – 33 ]. The underlying assumption is that patients and other stakeholders hold unique perspectives and experiences that add value beyond their own single story, making the research more relevant and beneficial to researchers, study participants and (future) patients alike [ 34 , 35 ]. Using the example of patients on or nearing dialysis, a recent scoping review found that 80% of clinical research did not address the top 10 research priorities identified by patients and caregivers [ 32 , 36 ]. In this sense, the involvement of the relevant stakeholders, especially patients and relatives, is increasingly being seen as a quality indicator in and of itself.

How not to assess qualitative research

The above overview does not include certain items that are routine in assessments of quantitative research. What follows is a non-exhaustive, non-representative, experience-based list of the quantitative criteria often applied to the assessment of qualitative research, as well as an explanation of the limited usefulness of these endeavours.

Protocol adherence

Given the openness and flexibility of qualitative research, it should not be assessed by how well it adheres to pre-determined and fixed strategies – in other words: its rigidity. Instead, the assessor should look for signs of adaptation and refinement based on lessons learned from earlier steps in the research process.

Sample size

For the reasons explained above, qualitative research does not require specific sample sizes, nor does it require that the sample size be determined a priori [ 1 , 14 , 27 , 37 – 39 ]. Sample size can only be a useful quality indicator when related to the research purpose, the chosen methodology and the composition of the sample, i.e. who was included and why.

Randomisation

While some authors argue that randomisation can be used in qualitative research, this is not commonly the case, as neither its feasibility nor its necessity or usefulness has been convincingly established for qualitative research [ 13 , 27 ]. Relevant disadvantages include the negative impact of a too large sample size as well as the possibility (or probability) of selecting “ quiet, uncooperative or inarticulate individuals ” [ 17 ]. Qualitative studies do not use control groups, either.

Interrater reliability, variability and other “objectivity checks”

The concept of “interrater reliability” is sometimes used in qualitative research to assess to which extent the coding approach overlaps between the two co-coders. However, it is not clear what this measure tells us about the quality of the analysis [ 23 ]. This means that these scores can be included in qualitative research reports, preferably with some additional information on what the score means for the analysis, but it is not a requirement. Relatedly, it is not relevant for the quality or “objectivity” of qualitative research to separate those who recruited the study participants and collected and analysed the data. Experiences even show that it might be better to have the same person or team perform all of these tasks [ 20 ]. First, when researchers introduce themselves during recruitment this can enhance trust when the interview takes place days or weeks later with the same researcher. Second, when the audio-recording is transcribed for analysis, the researcher conducting the interviews will usually remember the interviewee and the specific interview situation during data analysis. This might be helpful in providing additional context information for interpretation of data, e.g. on whether something might have been meant as a joke [ 18 ].

Not being quantitative research

Being qualitative research instead of quantitative research should not be used as an assessment criterion if it is used irrespectively of the research problem at hand. Similarly, qualitative research should not be required to be combined with quantitative research per se – unless mixed methods research is judged as inherently better than single-method research. In this case, the same criterion should be applied for quantitative studies without a qualitative component.

The main take-away points of this paper are summarised in Table ​ Table1. 1 . We aimed to show that, if conducted well, qualitative research can answer specific research questions that cannot to be adequately answered using (only) quantitative designs. Seeing qualitative and quantitative methods as equal will help us become more aware and critical of the “fit” between the research problem and our chosen methods: I can conduct an RCT to determine the reasons for transportation delays of acute stroke patients – but should I? It also provides us with a greater range of tools to tackle a greater range of research problems more appropriately and successfully, filling in the blind spots on one half of the methodological spectrum to better address the whole complexity of neurological research and practice.
