Unit of Analysis: Definition, Types & Examples

A unit of analysis is what you discuss after your research, probably what you would regard to be the primary emphasis of your research.

The unit of analysis is the people or things whose qualities will be measured. The unit of analysis is an essential part of a research project. It’s the main thing that a researcher looks at in his research.

A unit of analysis is the object about which you hope to have something to say at the end of your analysis, perhaps the major subject of your research.

In this blog, we will define:

Definition of “unit of analysis”

Types of “unit of analysis”

What is a unit of analysis.

A unit of analysis is the thing you want to discuss after your research, probably what you would regard to be the primary emphasis of your research.

The researcher plans to comment on the primary topic or object in the research as a unit of analysis. The research question plays a significant role in determining it. The “who” or “what” that the researcher is interested in investigating is, to put it simply, the unit of analysis.

In his book “Man, the State, and War” from 2001, author Waltz divides the world into three distinct spheres of study: the individual, the state, and war.

Understanding the reasoning behind the unit of analysis is vital. The likelihood of fruitful research increases if the rationale is understood. An individual, group, organization, nation, social phenomenon, etc., are a few examples.

LEARN ABOUT: Data Analytics Projects

In business research, there are almost unlimited types of possible analytical units. Data analytics and data analysis are closely related processes that involve extracting insights from data to make informed decisions. Even though the most typical unit of analysis is the individual, many research questions can be more precisely answered by looking at other types of units. Let’s find out,

Individual Level

The most prevalent unit of analysis in business research is the individual. These are the primary analytical units. The researcher may be interested in looking into:

Employee actions
Perceptions
Attitudes, or opinions.

Employees may come from wealthy or low-income families, as well as from rural or metropolitan areas.

A researcher might investigate if personnel from rural areas are more likely to arrive on time than those from urban areas. Additionally, he can check whether workers from rural areas who come from poorer families arrive on time compared to those from rural areas who come from wealthy families.

Each time, the individual (employee) serving as the analytical unit is discussed and explained. Employee analysis as a unit of analysis can shed light on issues in business, including customer and human resource behavior.

For example, employee work satisfaction and consumer purchasing patterns impact business, making research into these topics vital.

Psychologists typically concentrate on the research of individuals. The research of individuals may significantly aid the success of a firm. Their knowledge and experiences reveal vital information. Individuals are so heavily utilized in business research.

Aggregates Level

People are not usually the focus of social science research. By combining the reactions of individuals, social scientists frequently describe and explain social interactions, communities, and groupings. Additionally, they research the collective of individuals, including communities, groups, and countries.

Aggregate levels can be divided into two types: Groups (groups with an ad hoc structure) and Organizations (groups with a formal organization).

Groups of people make up the following levels of the unit of analysis. A group is defined as two or more individuals interacting, having common traits, and feeling connected to one another.

Many definitions also emphasize interdependence or objective resemblance (Turner, 1982; Platow, Grace, & Smithson, 2011) and those who identify as group members (Reicher, 1982) .

As a result, society and gangs serve as examples of groups. According to Webster’s Online Dictionary (2012), they can resemble some clubs but be far less formal.

Siblings, identical twins, family, and small group functioning are examples of studies with many units of analysis.

In such circumstances, a whole group might be compared to another. Families, gender-specific groups, pals, Facebook groups, and work departments can all be groups.

By analyzing groups, researchers can learn how they form and how age, experience, class, and gender affect them. When aggregated, an individual’s data describes the group to which they belong.

LEARN ABOUT: Data Management Framework

Sociologists study groups like economists. Businesspeople form teams to complete projects. They’re continually researching groups and group behavior.

Organizations

The next level of the unit of analysis is organizations, which are groups of people. Organizations are groups set up formally. It could include businesses, religious groups, parts of the military, colleges, academic departments, supermarkets, business groups, and so on.

The social organization includes things like sexual composition, styles of leadership, organizational structure, systems of communication, and so on. (Susan & Wheelan, 2005; Chapais & Berman, 2004) . (Lim, Putnam, and Robert, 2010) say that well-known social organizations and religious institutions are among them.

Moody, White, and Douglas (2003) say that social organizations are hierarchical. Hasmath, Hildebrandt, and Hsu (2016) say that social organizations can take different forms. For example, they can be made by institutions like schools or governments.

Sociology, economics, political science, psychology, management, and organizational communication (Douma & Schreuder, 2013) are some social science fields that study organizations.

Organizations are different from groups in that they are more formal and have better organization. A researcher might want to study a company to generalize its results to the whole population of companies.

One way to look at an organization is by the number of employees, the net annual revenue, the net assets, the number of projects, and so on. He might want to know if big companies hire more or fewer women than small companies.

Organization researchers might be interested in how companies like Reliance, Amazon, and HCL affect our social and economic lives. People who work in business often study business organizations.

Social Level

The social level has 2 types,

Social Artifacts Level

Things are studied alongside humans. Social artifacts are human-made objects from diverse communities. Social artifacts are items, representations, assemblages, institutions, knowledge, and conceptual frameworks used to convey, interpret, or achieve a goal (IGI Global, 2017).

Cultural artifacts are anything humans generate that reveals their culture (Watts, 1981).

Social artifacts include books, newspapers, advertising, websites, technical devices, films, photographs, paintings, clothes, poems, jokes, students’ late excuses, scientific breakthroughs, furniture, machines, structures, etc. Infinite.

Humans build social objects for social behavior. As people or groups suggest a population in business research, each social object implies a class of items.

Same-class goods include business books, magazines, articles, and case studies. A business magazine’s quantity of articles, frequency, price, content, and editor in a research study may be characterized.

Then, a linked magazine’s population might be evaluated for description and explanation. Marx W. Wartofsky (1979) defined artifacts as primary artifacts utilized in production (like a camera), secondary artifacts connected to primary artifacts (like a camera user manual), and tertiary objects related to representations of secondary artifacts (like a camera user-manual sculpture).

An artifact’s scientific study reveals its creators and users. The artifacts researcher may be interested in advertising, marketing, distribution, buying, etc.

Social Interaction Level

Social artifacts include social interaction. Such as:

Eye contact with a coworker
Buying something in a store
Friendship decisions
Road accidents
Airline hijackings
Professional counseling
Whatsapp messaging

A researcher might study youthful employees’ smartphone addictions . Some addictions may involve social media, while others involve online games and movies that inhibit connection.

Smartphone addictions are examined as a societal phenomenon. Observation units are probably individuals (employees).

Anthropologists typically study social artifacts. They may be interested in the social order. A researcher who examines social interactions may be interested in how broader societal structures and factors impact daily behavior, festivals, and weddings.

LEARN ABOUT: Level of Analysis

Even though there is no perfect way to do research, it is generally agreed that researchers should try to find a unit of analysis that keeps the context needed to make sense of the data.

Researchers should consider the details of their research when deciding on the unit of analysis.

They should keep in mind that consistent use of these units throughout the analysis process (from coding to developing categories and themes to interpreting the data) is essential to gaining insight from qualitative data and protecting the reliability of the results.

What is a unit of analysis?

A unit of analysis is an object of study within a research project. It is the smallest unit a researcher can use to identify and describe a phenomenon—the 'what' or 'who' the researcher wants to study.

For example, suppose a consultancy firm is hired to train the sales team in a solar company that is struggling to meet its targets. To evaluate their performance after the training, the unit of analysis would be the sales team—it's the main focus of the study.

Different methods, such as surveys , interviews, or sales data analysis, can be used to evaluate the sales team's performance and determine the effectiveness of the training.

Units of observation vs. units of analysis

A unit of observation refers to the actual items or units being measured or collected during the research. In contrast, a unit of analysis is the entity that a researcher can comment on or make conclusions about at the end of the study.

In the example of the solar company sales team, the unit of observation would be the individual sales transactions or deals made by the sales team members. In contrast, the unit of analysis would be the sales team as a whole.

The firm may observe and collect data on individual sales transactions, but the ultimate conclusion would be based on the sales team's overall performance, as this is the entity that the firm is hired to improve.

In some studies, the unit of observation may be the same as the unit of analysis, but researchers need to define both clearly to themselves and their audiences.

Unit of analysis types

Below are the main types of units of analysis:

Individuals – These are the smallest levels of analysis.

Groups – These are people who interact with each other.

Artifacts –These are material objects created by humans that a researcher can study using empirical methods.

Geographical units – These are smaller than a nation and range from a province to a neighborhood.

Social interactions – These are formal or informal interactions between society members.

Importance of selecting the correct unit of analysis in research

Selecting the correct unit of analysis helps reveal more about the subject you are studying and how to continue with the research. It also helps determine the information you should use in the study. For instance, if a researcher has a large sample, the unit of analysis will help decide whether to focus on the whole population or a subset of it.

Examples of a unit of analysis

Here are examples of a unit of analysis:

Individuals – A person, an animal, etc.

Groups – Gangs, roommates, etc.

Artifacts – Phones, photos, books, etc.

Geographical units – Provinces, counties, states, or specific areas such as neighborhoods, city blocks, or townships

Social interaction – Friendships, romantic relationships, etc.

Factors to consider when selecting a unit of analysis

The main things to consider when choosing a unit of analysis are:

Research questions and hypotheses

Research questions can be descriptive if the study seeks to describe what exists or what is going on.

It can be relational if the study seeks to look at the relationship between variables. Or, it can be causal if the research aims at determining whether one or more variables affect or cause one or more outcome variables.

Your study's research question and hypothesis should guide you in choosing the correct unit of analysis.

Data availability and quality

Consider the nature of the data collected and the time spent observing each participant or studying their behavior. You should also consider the scale used to measure variables.

Some studies involve measuring every variable on a one-to-one scale, while others use variables with discrete values. All these influence the selection of a unit of analysis.

Feasibility and practicality

Look at your study and think about the unit of analysis that would be feasible and practical.

Theoretical framework and research design

The theoretical framework is crucial in research as it introduces and describes the theory explaining why the problem under research exists. As a structure that supports the theory of a study, it is a critical consideration when choosing the unit of analysis. Moreover, consider the overall strategy for collecting responses to your research questions.

Common mistakes when choosing a unit of analysis

Below are common errors that occur when selecting a unit of analysis:

Reductionism

This error occurs when a researcher uses data from a lower-level unit of analysis to make claims about a higher-level unit of analysis. This includes using individual-level data to make claims about groups.

However, claiming that Rosa Parks started the movement would be reductionist. There are other factors behind the rise and success of the US civil rights movement. These include the Supreme Court’s historic decision to desegregate schools, protests over legalized racial segregation, and the formation of groups such as the Student Nonviolent Coordinating Committee (SNCC). In short, the movement is attributable to various political, social, and economic factors.

Ecological fallacy

This mistake occurs when researchers use data from a higher-level unit of analysis to make claims about one lower-level unit of analysis. It usually occurs when only group-level data is collected, but the researcher makes claims about individuals.

For instance, let's say a study seeks to understand whether addictions to electronic gadgets are more common in certain universities than others.

The researcher moves on and obtains data on the percentage of gadget-addicted students from different universities around the country. But looking at the data, the researcher notes that universities with engineering programs have more cases of gadget additions than campuses without the programs.

Concluding that engineering students are more likely to become addicted to their electronic gadgets would be inappropriate. The data available is only about gadget addiction rates by universities; thus, one can only make conclusions about institutions, not individual students at those universities.

Making claims about students while the data available is about the university puts the researcher at risk of committing an ecological fallacy.

The lowdown

A unit of analysis is what you would consider the primary emphasis of your study. It is what you want to discuss after your study. Researchers should determine a unit of analysis that keeps the context required to make sense of the data. They should also keep the unit of analysis in mind throughout the analysis process to protect the reliability of the results.

What is the most common unit of analysis?

The individual is the most prevalent unit of analysis.

Can the unit of analysis and the unit of observation be one?

Some situations have the same unit of analysis and observation. For instance, let's say a tutor is hired to improve the oral French proficiency of a student who finds it difficult. A few months later, the tutor wants to evaluate the student's proficiency based on what they have taught them for the time period. In this case, the student is both the unit of analysis and the unit of observation.

Introduction

A unit of analysis is the smallest level of analysis for a research project. It’s important to choose the right unit of analysis because it helps you make more accurate conclusions about your data.

What Is a Unit of Analysis?

A unit of analysis is the smallest element in a data set that can be used to identify and describe a phenomenon or the smallest unit that can be used to gather data about a subject. The unit of analysis will determine how you will define your variables, which are the things that you measure in your data.

If you want to understand why people buy a particular product, you should choose a unit of analysis that focuses on buying behavior. This means choosing a unit of analysis that is relevant to your research topic and question .

For example, if you want to study the needs of soldiers in a war zone, you will need to choose an appropriate unit of analysis for this study: soldiers or the war zone. In this case, choosing the right unit of analysis would be important because it could help you decide if your research design is appropriate for this particular subject and situation.

Why is Choosing the Right Unit of Analysis Important?

The unit of analysis is important because it helps you understand what you are trying to find out about your subject, and it also helps you to make decisions about how to proceed with your research.

Choosing the right unit of analysis is also important because it determines what information you’re going to use in your research. If you have a small sample, then you’ll have to choose whether or not to focus on the entire population or just a subset of it.

If you have a large sample, then you’ll be able to find out more about specific groups within your population. For example, if you want to understand why people buy certain types of products, then you should choose a unit of analysis that focuses on buying behavior.

This means choosing a unit of analysis that is relevant to your research topic and question.

Unit of Analysis vs Unit of Observation

Unit of analysis is a term used to refer to a particular part of a data set that can be analyzed. For example, in the case of a survey, the unit of analysis is an individual: the person who was selected to take part in the survey.

Unit of analysis is used in the social sciences to refer to the individuals or groups that have been studied. It can also be referred to as the unit of observation.

Unit of observation refers to a specific person or group in the study being observed by the researcher. An example would be a particular town, census tract, state, or other geographical location being studied by researchers conducting research on crime rates in that area.

Unit of analysis refers to the individual or group being studied by the researcher. An example would be an entire town being analyzed for crime rates over time.

Types of “Unit of Analysis”

The unit of analysis is a way to understand and study a phenomenon. There are four main types of unit of analysis: individuals, groups, artifacts (books, photos, newspapers), and geographical units (towns, census tracts, states).

Individuals are the smallest level of analysis. For example, an individual may be a person or an animal. A group can be composed of individuals or a collection of people who interact with each other. For example, an individual might go to college with other individuals or a family might live together as roommates.
An artifact is anything that can be studied using empirical methods—including books and photos but also any physical object like knives or phones.
A geographical unit is smaller than an entire country but larger than just one city block or neighborhood; it may be smaller than just two houses but larger than just two houses in the same street.
Social interactions include dyadic relations (such as friendships or romantic relationships) and divorces among many other things such as arrests.

Examples of Each Type of Unit of Analysis

Individuals are the smallest unit of analysis. An individual is a person, animal, or thing. For example, an individual can be a person or a building.
Artifacts are the next largest units of analysis. An artifact is something produced by human beings and is not alive. For example, a child’s toy is an artifact. Artifacts can include any material object that was produced by human activity and which has meaning to someone. Artifacts can be tangible or intangible and may be produced intentionally or accidentally.
Geographical units are large geographic areas such as states, counties, provinces, etc. Geographical units may also refer to specific locations within these areas such as cities or townships.
Social interaction refers to interactions between members of society (e.g., family members interacting with each other). Social interaction includes both formal interactions (such as attending school) and informal interactions (such as talking on the phone).

How Does a Social Scientist Choose a Unit of Analysis?

Social scientists choose a unit of analysis based on the purpose of their research, their research question, and the type of data they have. For example, if they are trying to understand the relationship between a person’s personality and their behavior, they would choose to study personality traits.

For example, if a researcher wanted to study the effects of legalizing marijuana on crime rates, they may choose to use administrative data from police departments. However, if they wanted to study how culture influences crime rates, they might use survey data from smaller groups of people who are further removed from the influence of culture (e.g., individuals living in different areas or countries).

Factors to Consider When Choosing a Unit of Analysis

The unit of analysis is the object or person that you are studying, and it determines what kind of data you are collecting and how you will analyze it.

Factors to consider when choosing a unit of analysis include:

What is your purpose for studying this topic? Is it for a research paper or an article? If so, which type of paper do you want to write?
What is the most appropriate unit for your study? If you are studying a specific event or period of time, this may be obvious. But if your focus is broader, such as all social sciences or all human development, then you need to determine how broad your scope should be before beginning any research process (see question one above) so that you know where to start in order for it to be effective (see question three below).
How do other people define their units? This can be helpful when trying to understand what other people mean when they use certain terms like “social science” or “human development” because they may define those terms differently than what you would expect them to.
The nature of the data collected. Is it quantitative or qualitative? If it’s qualitative, what kind of data is collected? How much time was spent observing each participant/examining their behavior?
The scale used to measure variables. Is every variable measured on a one-to-one scale (like measurements between people)? Or do some variables only take on discrete values (like yes/no questions)?

The unit of analysis is the smallest part of a data set that you analyze. It’s important to remember that your data is made up of more than just one unit—you have lots of different units in your dataset, and each of those units has its own characteristics that you need to think about when you’re trying to analyze it.

The Unit of Analysis Explained

By DiscoverPhDs
October 3, 2020

The unit of analysis refers to the main parameter that you’re investigating in your research project or study. Example of the different types of unit analysis that may be used in a project include:

Individual people
Groups of people
Objects such as photographs, newspapers and books
Geographical unit based on parameters such as cities or counties
Social parameters such as births, deaths, divorces

The unit of analysis is named as such because the unit type is determined based on the actual data analysis that you perform in your project or study.

For example, if your research is based around data on exam grades for students at two different universities, then the unit of analysis is the data for the individual student due to each student having an exam score associated with them.

Conversely if your study is based on comparing noise level data between two different lecture halls full of students, then your unit of analysis here is the collective group of students in each hall rather than any data associated with an individual student.

In the same research study involving the same students, you may perform different types of analysis and this will be reflected by having different units of analysis. In the example of student exam scores, if you’re comparing individual exam grades then the unit of analysis is the individual student.

On the other hand, if you’re comparing the average exam grade between two universities, then the unit of analysis is now the group of students as you’re comparing the average of the group rather than individual exam grades.

These different levels of hierarchies of units of analysis can become complex with multiple levels. In fact, its complexity has led to a new field of statistical analysis that’s commonly known as hierarchical modelling.

As a researcher, you need to be clear on what your specific research questio n is. Based on this, you can define each data, observation or other variable and how they make up your dataset.

A clarity of your research question will help you identify your analysis units and the appropriate sample size needed to obtain a meaningful result (and is this a random sample/sampling unit or something else).

In developing your research method, you need to consider whether you’ll need any repeated observation of each measurement. You also need to consider whether you’re working with qualitative data/qualitative research or if this is quantitative content analysis.

The unit of analysis of your study is the specifically ‘who’ or what’ it is that your analysing – for example are you analysing the individual student, the group of students or even the whole university. You may have to consider a different unit of analysis based on the concept you’re considering, even if working with the same observation data set.

7.3 Unit of analysis and unit of observation

Learning objectives.

Define units of analysis and units of observation, and describe the two common errors people make when they confuse the two

Another point to consider when designing a research project, and which might differ slightly in qualitative and quantitative studies, has to do with units of analysis and units of observation. These two items concern what you, the researcher, actually observe in the course of your data collection and what you hope to be able to say about those observations. A unit of analysis is the entity that you wish to be able to say something about at the end of your study, probably what you’d consider to be the main focus of your study. A unit of observation is the item (or items) that you actually observe, measure, or collect in the course of trying to learn something about your unit of analysis.

In a given study, the unit of observation might be the same as the unit of analysis, but that is not always the case. For example, a study on electronic gadget addiction may interview undergraduate students (our unit of observation) for the purpose of saying something about undergraduate students (our unit of analysis) and their gadget addiction. Perhaps, if we were investigating gadget addiction in elementary school children (our unit of analysis), we might collect observations from teachers and parents (our units of observation) because younger children may not report their behavior accurately. In this case and many others, units of analysis are not the same as units of observation. What is required, however, is for researchers to be clear about how they define their units of analysis and observation, both to themselves and to their audiences.

More specifically, your unit of analysis will be determined by your research question. Your unit of observation, on the other hand, is determined largely by the method of data collection that you use to answer that research question. We’ll take a closer look at methods of data collection later on in the textbook. For now, let’s consider again a study addressing students’ addictions to electronic gadgets. We’ll consider first how different kinds of research questions about this topic will yield different units of analysis. Then, we’ll think about how those questions might be answered and with what kinds of data. This leads us to a variety of units of observation.

If we were to explore which students are most likely to be addicted to their electronic gadgets, our unit of analysis would be individual students. We might mail a survey to students on campus, and our aim would be to classify individuals according to their membership in certain social groups in order to see how membership in those classes correlated with gadget addiction. For example, we might find that majors in new media, men, and students with high socioeconomic status are all more likely than other students to become addicted to their electronic gadgets. Another possibility would be to explore how students’ gadget addictions differ and how are they similar. In this case, we could conduct observations of addicted students and record when, where, why, and how they use their gadgets. In both cases, one using a survey and the other using observations, data are collected from individual students. Thus, the unit of observation in both examples is the individual.

Another common unit of analysis in social science inquiry is groups. Groups of course vary in size, and almost no group is too small or too large to be of interest to social scientists. Families, friendship groups, and group therapy participants are some common examples of micro-level groups examined by social scientists. Employees in an organization, professionals in a particular domain (e.g., chefs, lawyers, social workers), and members of clubs (e.g., Girl Scouts, Rotary, Red Hat Society) are all meso-level groups that social scientists might study. Finally, at the macro-level, social scientists sometimes examine citizens of entire nations or residents of different continents or other regions.

A study of student addictions to their electronic gadgets at the group level might consider whether certain types of social clubs have more or fewer gadget-addicted members than other sorts of clubs. Perhaps we would find that clubs that emphasize physical fitness, such as the rugby club and the scuba club, have fewer gadget-addicted members than clubs that emphasize cerebral activity, such as the chess club and the women’s studies club. Our unit of analysis in this example is groups because groups are what we hope to say something about. If we had instead asked whether individuals who join cerebral clubs are more likely to be gadget-addicted than those who join social clubs, then our unit of analysis would have been individuals. In either case, however, our unit of observation would be individuals.

Organizations are yet another potential unit of analysis that social scientists might wish to say something about. Organizations include entities like corporations, colleges and universities, and even nightclubs. At the organization level, a study of students’ electronic gadget addictions might explore how different colleges address the problem of electronic gadget addiction. In this case, our interest lies not in the experience of individual students but instead in the campus-to-campus differences in confronting gadget addictions. A researcher conducting a study of this type might examine schools’ written policies and procedures, so her unit of observation would be documents. However, because she ultimately wishes to describe differences across campuses, the college would be her unit of analysis.

In sum, there are many potential units of analysis that a social worker might examine, but some of the most common units include the following:

Individuals
Organizations

One common error people make when it comes to both causality and units of analysis is something called the ecological fallacy . This occurs when claims about one lower-level unit of analysis are made based on data from some higher-level unit of analysis. In many cases, this occurs when claims are made about individuals, but only group-level data have been gathered. For example, we might want to understand whether electronic gadget addictions are more common on certain campuses than on others. Perhaps different campuses around the country have provided us with their campus percentage of gadget-addicted students, and we learn from these data that electronic gadget addictions are more common on campuses that have business programs than on campuses without them. We then conclude that business students are more likely than non-business students to become addicted to their electronic gadgets. However, this would be an inappropriate conclusion to draw. Because we only have addiction rates by campus, we can only draw conclusions about campuses, not about the individual students on those campuses. Perhaps the social work majors on the business campuses are the ones that caused the addiction rates on those campuses to be so high. The point is we simply don’t know because we only have campus-level data. By drawing conclusions about students when our data are about campuses, we run the risk of committing the ecological fallacy.

On the other hand, another mistake to be aware of is reductionism. Reductionism occurs when claims about some higher-level unit of analysis are made based on data from some lower-level unit of analysis. In this case, claims about groups or macro-level phenomena are made based on individual-level data. An example of reductionism can be seen in some descriptions of the civil rights movement. On occasion, people have proclaimed that Rosa Parks started the civil rights movement in the United States by refusing to give up her seat to a white person while on a city bus in Montgomery, Alabama, in December 1955. Although it is true that Parks played an invaluable role in the movement, and that her act of civil disobedience gave others courage to stand up against racist policies, beliefs, and actions, to credit Parks with starting the movement is reductionist. Surely the confluence of many factors, from fights over legalized racial segregation to the Supreme Court’s historic decision to desegregate schools in 1954 to the creation of groups such as the Student Nonviolent Coordinating Committee (to name just a few), contributed to the rise and success of the American civil rights movement. In other words, the movement is attributable to many factors—some social, others political and others economic. Did Parks play a role? Of course she did—and a very important one at that. But did she cause the movement? To say yes would be reductionist.

It would be a mistake to conclude from the preceding discussion that researchers should avoid making any claims whatsoever about data or about relationships between levels of analysis. While it is important to be attentive to the possibility for error in causal reasoning about different levels of analysis, this warning should not prevent you from drawing well-reasoned analytic conclusions from your data. The point is to be cautious and conscientious in making conclusions between levels of analysis. Errors in analysis come from a lack of rigor and deviating from the scientific method.

Key Takeaways

A unit of analysis is the item you wish to be able to say something about at the end of your study while a unit of observation is the item that you actually observe.
When researchers confuse their units of analysis and observation, they may be prone to committing either the ecological fallacy or reductionism.
Ecological fallacy- claims about one lower-level unit of analysis are made based on data from some higher-level unit of analysis
Reductionism- when claims about some higher-level unit of analysis are made based on data at some lower-level unit of analysis
Unit of analysis- entity that a researcher wants to say something about at the end of her study
Unit of observation- the item that a researcher actually observes, measures, or collects in the course of trying to learn something about her unit of analysis

4.3 Unit of analysis and unit of observation

Learning objectives.

Define units of analysis and units of observation, and describe the two common errors people make when they confuse the two

Another common unit of analysis in social science inquiry is groups. Groups of course vary in size, and almost no group is too small or too large to be of interest to social scientists. Families, friendship groups, and group therapy participants are some common examples of micro-level groups examined by social scientists. Employees in an organization, professionals in a particular domain (e.g., chefs, lawyers, social workers), and members of clubs (e.g., Girl Scouts, Rotary, Red Hat Society) are all meso-level groups that social scientists might study. Finally, at the macro-level, social scientists sometimes examine policies, citizens of entire nations, or residents of different continents or other regions.

In sum, there are many potential units of analysis that a social worker might examine, but some of the most common units include the following: i ndividuals, g roups, and o rganizations.

Measurement and Units of Analysis

24 Units of Analysis and Units of Observation

A unit of analysis is the entity that you wish to be able to say something about at the end of your study, probably what you would consider to be the main focus of your study. A unit of observation is the item (or items) that you actually observe, measure, or collect in the course of trying to learn something about your unit of analysis. In a given study, the unit of observation might be the same as the unit of analysis, but that is not always the case. Further, units of analysis are not required to be the same as units of observation. What is required, however, is for researchers to be clear about how they define their units of analysis and observation, both to themselves and to their audiences. More specifically, your unit of analysis will be determined by your research question. Your unit of observation, on the other hand, is determined largely by the method of data collection that you use to answer that research question.

To demonstrate these differences, let us look at the topic of students’ addictions to their cell phones. We will consider first how different kinds of research questions about this topic will yield different units of analysis. Then we will think about how those questions might be answered and with what kinds of data. This leads us to a variety of units of observation.

If I were to ask, “Which students are most likely to be addicted to their cell phones?” our unit of analysis would be the individual. We might mail a survey to students on a university or college campus, with the aim to classify individuals according to their membership in certain social classes and, in turn, to see how membership in those classes correlate with addiction to cell phones. For example, we might find that students studying media, males, and students with high socioeconomic status are all more likely than other students to become addicted to their cell phones. Alternatively, we could ask, “How do students’ cell phone addictions differ and how are they similar? In this case, we could conduct observations of addicted students and record when, where, why, and how they use their cell phones. In both cases, one using a survey and the other using observations, data are collected from individual students. Thus, the unit of observation in both examples is the individual. But the units of analysis differ in the two studies. In the first one, our aim is to describe the characteristics of individuals. We may then make generalisations about the populations to which these individuals belong, but our unit of analysis is still the individual. In the second study, we will observe individuals in order to describe some social phenomenon, in this case, types of cell phone addictions. Consequently, our unit of analysis would be the social phenomenon.

Another common unit of analysis in sociological inquiry is groups. Groups of course vary in size, and almost no group is too small or too large to be of interest to sociologists. Families, friendship groups, and street gangs make up some of the more common microlevel groups examined by sociologists. Employees in an organization, professionals in a particular domain (e.g., chefs, lawyers, sociologists), and members of clubs (e.g., Girl Guides, Rotary, Red Hat Society) are all meso-level groups that sociologists might study. Finally, at the macro level, sociologists sometimes examine citizens of entire nations or residents of different continents or other regions.

A study of student addictions to their cell phones at the group level might consider whether certain types of social clubs have more or fewer cell phone-addicted members than other sorts of clubs. Perhaps we would find that clubs that emphasize physical fitness, such as the rugby club and the scuba club, have fewer cell phone-addicted members than clubs that emphasize cerebral activity, such as the chess club and the sociology club. Our unit of analysis in this example is groups. If we had instead asked whether people who join cerebral clubs are more likely to be cell phone-addicted than those who join social clubs, then our unit of analysis would have been individuals. In either case, however, our unit of observation would be individuals.

Organizations are yet another potential unit of analysis that social scientists might wish to say something about. Organizations include entities like corporations, colleges and universities, and even night clubs. At the organization level, a study of students’ cell phone addictions might ask, “How do different colleges address the problem of cell phone addiction?” In this case, our interest lies not in the experience of individual students but instead in the campus-to-campus differences in confronting cell phone addictions. A researcher conducting a study of this type might examine schools’ written policies and procedures, so his unit of observation would be documents. However, because he ultimately wishes to describe differences across campuses, the college would be his unit of analysis.

Social phenomena are also a potential unit of analysis. Many sociologists study a variety of social interactions and social problems that fall under this category. Examples include social problems like murder or rape; interactions such as counselling sessions, Facebook chatting, or wrestling; and other social phenomena such as voting and even cell phone use or misuse. A researcher interested in students’ cell phone addictions could ask, “What are the various types of cell phone addictions that exist among students?” Perhaps the researcher will discover that some addictions are primarily centred around social media such as chat rooms, Facebook, or texting while other addictions centre single-player games that discourage interaction with others. The resultant typology of cell phone addictions would tell us something about the social phenomenon (unit of analysis) being studied. As in several of the preceding examples, however, the unit of observation would likely be individual people.

Finally, a number of social scientists examine policies and principles, the last type of unit of analysis we will consider here. Studies that analyse policies and principles typically rely on documents as the unit of observation. Perhaps a researcher has been hired by a college to help it write an effective policy against cell phone use in the classroom. In this case, the researcher might gather all previously written policies from campuses all over the country and compare policies at campuses where the use of cell phones in classroom is low to policies at campuses where the use of cell phones in the classroom is high.

In sum, there are many potential units of analysis that a sociologist might examine, but some of the most common units include the following:

Individuals
Organizations
Social phenomena
Policies and principles

One of the most important ideas in a research project is the unit of analysis . The unit of analysis is the major entity that you are analyzing in your study. For instance, any of the following could be a unit of analysis in a study:

individuals
artifacts (books, photos, newspapers)
geographical units (town, census tract, state)
social interactions (dyadic relations, divorces, arrests)

Why is it called the ‘unit of analysis’ and not something else (like, the unit of sampling)? Because it is the analysis you do in your study that determines what the unit is . For instance, if you are comparing the children in two classrooms on achievement test scores, the unit is the individual child because you have a score for each child. On the other hand, if you are comparing the two classes on classroom climate, your unit of analysis is the group, in this case the classroom, because you only have a classroom climate score for the class as a whole and not for each individual student. For different analyses in the same study you may have different units of analysis. If you decide to base an analysis on student scores, the individual is the unit. But you might decide to compare average classroom performance. In this case, since the data that goes into the analysis is the average itself (and not the individuals’ scores) the unit of analysis is actually the group. Even though you had data at the student level, you use aggregates in the analysis. In many areas of social research these hierarchies of analysis units have become particularly important and have spawned a whole area of statistical analysis sometimes referred to as hierarchical modeling . This is true in education, for instance, where we often compare classroom performance but collected achievement data at the individual student level.

3.2: Unit of Analysis and Errors

Page ID 124454

Learning Objective

Define units of analysis and units of observation, and describe the two common errors people make when they confuse the two.

Units of Analysis

Another point to consider when designing a research project, and which might differ slightly in qualitative and quantitative studies, has to do with units of analysis. A unit of analysis is the entity that you wish to be able to say something about at the end of your study, probably what you’d consider to be the main focus of your study.

More specifically, your unit of analysis will be determined by your research question. For now, let’s go back to an example about students’ addictions to electronic gadgets. We’ll consider first how different kinds of research questions about this topic will yield different units of analysis. Then we’ll think about how those questions might be answered and with what kinds of data.

If we were to ask, “Which students are most likely to be addicted to their electronic gadgets?” our unit of analysis would be the individual . We might mail a survey to students on campus, and our aim would be to classify individuals according to their membership in certain social classes in order to see how membership in those classes correlated with gadget addiction. For example, we might find that majors in new media, men, and students with high socioeconomic status are all more likely than other students to become addicted to their electronic gadgets. Another possibility would be to ask, “How do students’ gadget addictions differ, and how are they similar?” In this case, we could conduct observations of addicted students and record when, where, why, and how they use their gadgets. In both cases, one using a survey and the other using observations, data are collected from individual students. The units of analysis for both would be individuals.

Another common unit of analysis in sociological inquiry is groups . Groups of course vary in size, and almost no group is too small or too large to be of interest to sociologists. Families, friendship groups, and street gangs make up some of the more common groups examined by sociologists. Employees in an organization, professionals in a particular domain (e.g., chefs, lawyers, sociologists), and members of clubs (e.g., Girl Scouts, Rotary, Red Hat Society) are all larger groups that sociologists might study. Finally, at the macro level, sociologists sometimes examine citizens of entire nations or residents of different continents or other regions.

A study of student addictions to their electronic gadgets at the group level might consider whether certain types of social clubs have more or fewer gadget-addicted members than other sorts of clubs. Perhaps we would find that clubs that emphasize physical fitness, such as the rugby club and the scuba club, have fewer gadget-addicted members than clubs that emphasize cerebral activity, such as the chess club and the sociology club. Our unit of analysis in this example is groups. If we had instead asked whether people who join cerebral clubs are more likely to be gadget-addicted than those who join social clubs, then our unit of analysis would have been individuals.

Organizations are yet another potential unit of analysis that social scientists might wish to say something about. As you may recall from other courses organizations include entities like corporations, colleges and universities, and even night clubs. At the organization level, a study of students’ electronic gadget addictions might ask, “How do different colleges address the problem of electronic gadget addiction?” In this case, our interest lies not in the experience of individual students but instead in the campus-to-campus differences in confronting gadget addictions. A researcher conducting a study of this type might examine schools’ written policies and procedures, which could be social interactions or artifacts. However, because he ultimately wishes to describe differences across campuses, the college would be his unit of analysis.

Of course, it would be silly in a textbook focused on social scientific research to neglect social interactions and artifacts as units of analysis. Social interactions are relevant when studying individual humans and looking at interactions between them such as arguments, emails, fights, dancing, etc. A researcher interested in students’ electronic gadget addictions could ask, “What do students talk about on social media platforms?" We could use social interactions on various social media websites to study this.

Another of analysis, artifacts , are product of social beings and their behavior such as books, pottery, etc. A researcher interested in students’ electronic gadget addictions could ask, "How are different phones interfaces structured to encourage additions?"

In sum, there are many potential units of analysis that a sociologist might examine, but some of the most common units include the following:

Individuals
Organizations
Social interactions

Unit of Analysis Errors

One common error we see people make when it comes to both causality and units of analysis is something called the ecological fallacy . This occurs when claims about one lower-level unit of analysis are made based on data from some higher-level unit of analysis. In many cases, this occurs when claims are made about individuals, but only group-level data have been gathered. For example, we might want to understand whether electronic gadget addictions are more common on certain campuses than on others. Perhaps different campuses around the country have provided us with their campus percentage of gadget-addicted students, and we learn from these data that electronic gadget addictions are more common on campuses that have business programs than on campuses without them. We then conclude that business students are more likely than nonbusiness students to become addicted to their electronic gadgets. However, this would be an inappropriate conclusion to draw. Because we only have addiction rates by campus, we can only draw conclusions about campuses, not about the individual students on those campuses. Perhaps the sociology majors on the business campuses are the ones that caused the addiction rates on those campuses to be so high. The point is we simply don’t know because we only have campus-level data. By drawing conclusions about students when our data are about campuses, we run the risk of committing the ecological fallacy.

On the other hand, another mistake to be aware of is reductionism . Reductionism occurs when claims about some higher-level unit of analysis are made based on data from some lower-level unit of analysis. In this case, claims about groups are made based on individual-level data. An example of reductionism can be seen in some descriptions of the civil rights movement. On occasion, people have proclaimed that Rosa Parks started the civil rights movement in the United States by refusing to give up her seat to a white person while on a city bus in Montgomery, Alabama, in December 1955. Although it is true that Parks played an invaluable role in the movement, and that her act of civil disobedience gave others courage to stand up against racist policies, beliefs, and actions, to credit Parks with starting the movement is reductionist. Surely the confluence of many factors, from fights over legalized racial segregation to the Supreme Court’s historic decision to desegregate schools in 1954 to the creation of groups such as the Student Nonviolent Coordinating Committee (to name just a few), contributed to the rise and success of the American civil rights movement. In other words, the movement is attributable to many factors—some social, others political, others economic. Did Parks play a role? Of course she did—and a very important one at that. But did she cause the movement? To say yes would be reductionist.

It would be a mistake to conclude from the preceding discussion that researchers should avoid making any claims whatsoever about data or about relationships between variables. While it is important to be attentive to the possibility for error in causal reasoning about different levels of analysis, this warning should not prevent you from drawing well-reasoned analytic conclusions from your data. The point is to be cautious but not abandon entirely the social scientific quest to understand patterns of behavior.

KEY TAKEAWAYS

A unit of analysis is the item you wish to be able to say something about at the end of your study.
Ecological fallacy and reductionism are caused by generalizing to variables not of the same unit of analysis.
Do a Google News search for the term ecological fallacy . Chances are good you’ll come across a number of news editorials using this term. Read a few of these editorials or articles, and print one out. Demonstrate your understanding of the term ecological fallacy by writing a short answer discussing whether the author of the article you printed out used the term correctly.

Scientific Research and Methodology

2.9 units of observation and units of analysis.

Units of observation and units of analysis are important, but similar, concepts that need to be distinguished.

Think 2.10 (Designs) Consider this RQ:

In Australian 20-something men, is the average thickness of head hair strands the same for blonds and brunets ( Vaughn et al. 2009 ) ?

In this study, only one man of each hair colour is represented . There are 200 observations, but only two people are compared, so little is learnt about 20-something men in general .

We learn a lot about two men specifically. The Population is represented by just two men… so we don’t learn much about the population of men in general.

In this study, each individual hair is a unit of observation : the hair strands are what must be measured to obtain ‘thickness of head hair strands.’

But each blond hair comes from the same man, so each of those hairs have essentially lived their life together: They are washed at the same time, with the same shampoo, exposed to the same amount of sunlight and exercise, share genetics, etc. However, different people do their own thing and have their own genetics.

A similar, but different, concept is the unit of analysis .

In the hair-thickness study each person a unit of analysis . Importantly, the size of sample in the study is the number units of analysis; so here, there are only two examples of the population in the study . The size of the sample is just two.

Example 2.24 (Units of analysis) In the hair-strand study, each hair strand is a unit of observation : measurements of hair strand thickness are taken from individual hair strands.

Example 2.25 (Units of analysis) Consider a study comparing the percentage of females and males wearing sunglasses at a specific beach.

People in a group at the beach will probably not be operating ‘independently’: groups of people tend to behave similarly (but perhaps not identically). For example, a couple will often both be either wearing or not wearing sunglasses.

The researchers have two options; they could either

Use the people groups as the unit of analysis (some of which will be groups of one), and record data from just one person in any group.

Ideally, the researchers would specify before-hand which group member from which to take data (e.g., the person closest to the researchers when the group is spotted).

Alternatively, the researchers may decide not to use data from groups at all, and only gather data from individuals.

Example 2.26 (Units of analysis) A study compares two brands of car tyres. Four tyres of Brand A are allocated to each of Cars 1–5. Four tyres of Brand B are allocated to each of Cars 6–10.

After 12 months, the amount of wear is recorded on each tyre. The unit of observation is the tyre : the amount of wear is measured on each tyre.

A report on the Spectrum website reported the following:

Seven years ago, Peter Kind […] was reading a study about fragile X syndrome, a developmental condition characterized by severe intellectual disability and, often, autism […] Kind was surprised when he noticed a potentially serious statistical flaw. The research team had looked at 10 neurons from each of the 16 mice in the experiment, a practice that in itself was unproblematic. But in the statistical analysis, the researchers had analyzed each neuron as if it were an independent [individual observation]. That gave them 160 data points to work with, 10 times the number of mice in the experiment. ``The question is, are two neurons in the brain of the same animal truly independent data points? The answer is no,’’ Kind says. — Spectrum report

There were 16 units of analysis (mice) so the sample size is 16 mice, but the authors treated the \(16\times 10 = 160\) neurons as the sample size. The 10 neurons from each mouse have a lot in common: the genetic information was the same for all 10 neurons from each mouse.

The units of observation and units of analysis may be the same, and often are the same. However, they are sometimes different too, and it is crucial to be able to identify these situations. Importantly, studies compare units of analysis, not units of observation.

Example 2.27 (Units of analysis) A study compared two school physical activity (PA) programs. Each of 44 children (whose parents agreed for their children to participate in the study) were allocated to one of two PA program. The improvement in children’s fitness was measured for every student in the study after six months.

Think 2.11 (Units of analysis and observation) A study compared two school physical activity (PA) programs. Program 1 was allocated to be used at School A, while Program 2 was allocated to School B. In each school, 22 children (with parental consent) were observed and the improvement in children’s fitness was measured for each student after six months.

The following short video may help explain some of these concepts:

Remember this: A well-chosen unit of analysis acts as a beacon for accuracy and relevance throughout your scholarly inquiry. Continue reading to unlock the strategies for selecting this cornerstone of research design with precision—your project’s success depends on it.

Engage with us as we delve deeper into this critical aspect of research mastery.

Key Takeaways

Your research questions and hypotheses drive the choice of your unit of analysis, shaping how you collect and interpret data.
Avoid common mistakes like reductionism , which oversimplifies complex issues, and the ecological fallacy , where group-level findings are wrongly applied to individuals.
Consider the availability and quality of data when selecting your unit of analysis to ensure your research is feasible and conclusions are valid.
Differentiate between units of analysis (what you’re analyzing) and units of observation (what or who you’re observing) for clarity in your study.
Ensure that your chosen unit aligns with both the theoretical framework and practical considerations such as time and resources.

The unit of analysis in research refers to the level at which data is collected and analyzed. It is essential for researchers to understand the different types of units of analysis, as well as their significance in shaping the research process and outcomes.

Difference between Unit of Analysis and Unit of Observation

Understanding the difference between the unit of analysis and observation is key. Let us clarify this distinction: the unit of analysis is what you’ll ultimately analyze, while the unit of observation is what you observe or measure during the study.

For example, in using resonio for educational research, individual test scores are the units of analysis, while the students providing these scores are the units of observation.

This distinction is essential as it clarifies the specific aspect under scrutiny and what will yield measurable data. It also emphasizes that researchers must carefully consider both elements to ensure their alignment with research questions and objectives .

Types of Units of Analysis: Individual, Aggregates, and Social

Choosing the right unit of analysis for a research project is critical. The types of units of analysis include individual, aggregates, and social.

Individual: This type focuses on analyzing the attributes and characteristics of individual units, such as people or specific objects.
Aggregates: Aggregates involve analyzing groups or collections of individual units, such as neighborhoods, organizations, or communities.
Social: Social units of analysis emphasize analyzing broader social entities, such as cultures, societies, or institutions.

When selecting the right unit of analysis for a research project, researchers must consider various factors such as their research questions and hypotheses , data availability and quality, feasibility and practicality, as well as the theoretical framework and research design .

Each of these factors plays a crucial role in determining the most appropriate unit of analysis for the study.

Research Questions and Hypotheses

The research questions and hypotheses play a crucial role in determining the appropriate unit of analysis for a research project. They guide the researcher in identifying what exactly needs to be studied and analyzed, thereby influencing the selection of the most relevant unit of analysis.

The alignment between the research questions/hypotheses and the unit of analysis is essential to ensure that the study’s focus meets its intended objectives. Furthermore, clear research questions and hypotheses help define specific parameters for data collection and analysis, directly impacting which unit of analysis will best serve the study’s purpose.

It’s important to carefully consider how each research question or hypothesis relates to different potential units of analysis , as this connection will shape not only what you are studying but also how you will study it .

Data Availability and Quality

When considering the unit of analysis for a research project, researchers must take into account the availability and quality of data. The chosen unit of analysis should align with the available data sources to ensure that meaningful and accurate conclusions can be drawn.

Researchers need to evaluate whether the necessary data at the chosen level of analysis is accessible and reliable. Ensuring high-quality data will contribute to the validity and reliability of the study , enabling researchers to make sound interpretations and draw robust conclusions from their findings.

Choosing a unit of analysis without considering data availability and quality may lead to limitations in conducting thorough analysis or drawing valid conclusions. It is crucial for researchers to assess both factors before finalizing their selection, as it directly impacts the feasibility, accuracy, and rigor of their research project.

Feasibility and Practicality

When considering the feasibility and practicality of a unit of analysis for a research project, it is essential to assess the availability and quality of data related to the chosen unit.

Researchers should also evaluate whether the selected unit aligns with their theoretical framework and research design. The practical aspects such as time, resources, and potential challenges associated with analyzing the chosen unit must be thoroughly considered before finalizing the decision.

Moreover, it is crucial to ensure that the selected unit of analysis is feasible within the scope of the research questions and hypotheses. Additionally, researchers need to determine if the chosen unit can be effectively studied based on existing literature and sampling techniques utilized in similar studies.

By carefully evaluating these factors, researchers can make informed decisions regarding which unit of analysis will best suit their research goals.

Theoretical Framework and Research Design

The theoretical framework and research design establish the structure for a study based on existing theories and concepts. It guides the selection of the unit of analysis by providing a foundation for understanding how variables interact and influence one another.

Theoretical frameworks help to shape research questions , hypotheses, and data collection methods, ensuring that the chosen unit of analysis aligns with the study’s objectives. Research design serves as a blueprint outlining the procedures and techniques used to gather and analyze data, allowing researchers to make informed decisions regarding their unit of analysis while considering feasibility, practicality, and data availability .

Researchers often make the mistake of reductionism, where they oversimplify complex phenomena by focusing on one aspect. Another common mistake is the ecological fallacy, where conclusions about individual behavior are made based on group-level data.

Reductionism

Reductionism occurs when a researcher oversimplifies a complex phenomenon by analyzing it at too basic a level. This can lead to the loss of important nuances and details critical for understanding the broader context.

For instance, studying individual test scores without considering external factors like teaching quality or student motivation is reductionist. By focusing solely on one aspect, researchers miss out on comprehensive insights that may impact their findings.

In research projects, reductionism limits the depth of analysis and may result in skewed conclusions that don’t accurately reflect the real-world complexities. It’s essential for researchers to avoid reductionism by carefully selecting an appropriate unit of analysis that allows for a holistic understanding of the phenomenon under study.

Ecological Fallacy

The ecological fallacy involves making conclusions about individuals based on group-level data . This occurs when researchers mistakenly assume that relationships observed at the aggregate level also apply to individuals within that group.

For example, if a study finds a correlation between high levels of education and income at the city level, it doesn’t mean the same relationship applies to every individual within that city.

This fallacy can lead to erroneous generalizations and inaccurate assumptions about individuals based on broader trends. It is crucial for researchers to be mindful of this potential pitfall when selecting their unit of analysis, ensuring that their findings accurately represent the specific characteristics and behaviors of the individuals or entities under investigation.

Selecting the appropriate unit of analysis is critical for a research project’s success, shaping its focus and scope. Researchers must carefully align the chosen unit with their study objectives to ensure relevance.

The impact on findings and conclusions from this choice cannot be understated. Correctly choosing the unit of analysis can considerably influence the direction and outcomes of a research undertaking.

What is a unit of analysis?

The unit of analysis is an important concept whether you are conducting quantitative or qualitative research. It is related to another concept – the unit of observation. Though both are often used interchangeably (and can actually mean the same thing in some studies) they are not exactly the same conceptually.

This paper takes a closer look at what a unit of analysis is.

Unit of analysis explained

A unit of analysis is the main subject or entity whom the researcher intends to comment on in the study. It is mainly determined by the research question. Simply put, the unit of analysis is basically the ‘who’ or what’ that the researcher is interested in analyzing. For instance, an individual a group, organization, country, social phenomenon, etc.

Unit of observation explained

A unit of observation is any item from which data can be collected and measured. The unit of observation determines the data collection and measurement techniques to be used. Just like a unit of analysis, an individual, group, country, social phenomenon, etc can also be a unit of observation.

The examples below highlight the way varying research questions can bring about varying units of analysis. They will also examine how different units of observation can arise due to the types of data used to find answers to the research questions.

Consider the question “Which nation has the brightest chance of winning the forthcoming senior world cup.” Here, the unit of analysis is a country. To answer this question may require sampling the opinions of some soccer aficionados or experts. Hence, a survey can be conducted to aggregate expert views (e.g., coaches, players, analysts, reporters, administrators, etc) all over the world.

The objectives of the survey can include finding out if variables like continent of origin, venue of the tournament, climatic conditions, quality of players, level of preparation, and administrative efficiency play any role in the emergence of the champion. The survey’s findings may indicate that the quality of players, level of preparation, and the efficiency of a country’s soccer administrators are the most important determinants for winning the trophy.

Suppose an alternative question is asked, say “what are the differences and similarities in the ways countries prepare for the senior world cup.” One way to answer this question (assuming it is a world cup season) is to closely observe the preparation programmes of participating countries, including camping and physical training activities.

It can be deduced from the above examples that the unit of analysis is different in each case. In the first question, the country is the unit of analysis while in the second, a social phenomenon – preparation programme is the unit of analysis. In both examples, the unit of observation is the same – countries.

As noted in the definitions above, groups can also constitute a unit of analysis. In the question about which country is likely to win the senior world cup, for example, a group survey of a couple of soccer clubs can also be used to elicit responses. In this case, the unit of analysis is a group [say a professional football club].

For organizations, take the senior world cup example mentioned above as an example. Suppose a researcher poses the question “Are the levels of funding provided by soccer associations enough for them to challenge for the world cup?” Note that the main concern here is on soccer administrators and not on the teams of players. To determine the adequacy or otherwise of national teams’ funding, the researcher might need to source for and study various forms of documents. This means that documents are the unit of observation in this scenario. If he decides to make country-by-country comparisons on national team funding, then his unit of analysis will be the countries investigated.

Rules, policies, and principles are yet another form of units of analysis. Policy research, for example, will most likely involve analyzing several documents. Consider a soccer association that employs a lawyer to help draft a code of conduct for players [unit of analysis] preparing for the world cup in a closed camp. To come up with an acceptable code of conduct, the lawyer may decide to study all past code of conduct documents [unit of observation] of the association and maybe how the rules in the code have been observed and otherwise as well as the kind of penalties for the various violations of camp rules.

Unit of analysis and unit of observation as one

It has been suggested above that both concepts can be one and the same in some situations. For instance, a tutor can be hired to improve the oral or spoken English proficiency of a student struggling in that area. After a couple of months, the tutor decides to assess and evaluate the proficiency levels of his or her student based on what has been taught thus far. In this example, the student is both a unit of analysis as well as a unit of observation.

As noted from the discussion above, both the unit of analysis and the unit of observation are research concepts. These units can be individuals, groups, countries, organizations, social phenomena, etc. Though both concepts can be the same in some studies, differences also exist between them in other studies. Because of this confusing tendency, it is necessary that the researcher is as clear as possible when explaining the similarities or differences between both concepts.
