Research Paper vs Report: Breaking Down the Difference

The purpose of this article is to discuss the distinct differences between a research paper and a report. As academic writing has evolved, so too have the structures used to convey information in an organized and succinct manner. The distinctions between these two types of scholarly work are important for any student or researcher engaging in research-based activities as they can make all the difference when it comes to effectively conveying ideas and results accurately. This article will take an in-depth look at both reports and papers, discussing their similarities, differences, components, uses, and best practices for producing quality products that serve their intended purpose properly.

Ii. defining the differences between a research paper and report, iii. creating an outline for your project, iv. structuring the body of your work, v. ensuring proper citation techniques are utilized in your work, vi. finalizing, editing and publishing the completed project, vii. conclusion: comparing the benefits of writing either a research paper or report.

Research Paper and Report Writing: Writing research papers and reports can be challenging, especially for students who are new to the field of academic writing. Yet these two distinct forms of written communication are essential components in higher education. It is important to understand the differences between a research paper and a report so that one can approach each assignment with clarity of purpose and expectation from their readers.

In academic writing, there are two distinct types of documents which have important distinctions: the research paper and the report. Both styles require different approaches in terms of structure and content.

A research paper is a type of composition that requires its author to investigate an idea or concept through scholarly sources; it must then be presented in a written format. This style typically focuses on one particular point or argument with evidence used to back up assertions made throughout the document.

The main purpose of this type of work is usually to inform readers about certain topics while utilizing personal analysis as well as gathering information from credible sources. As such, it often contains detailed descriptions and explanations based upon current findings within relevant subject areas.

It’s also worth noting that most research papers will contain conclusions drawn by their authors regarding their respective fields – although these can take many forms including opinions, deductions, predictions etc.

A report differs from a research paper primarily because its focus lies more upon summarizing existing material rather than introducing new ideas. It’s generally defined as an orderly account containing facts pertaining to some aspect or aspects being investigated; reports tend not to offer recommendations nor do they include critical assessments. Reports are designed for specific audiences – academics, businesses etc., meaning they should always adhere closely to established guidelines depending on their target reader-base. Additionally, while visual elements may be included such as diagrams/charts/pictures etc.; text makes up the majority of any given report – usually accompanied by headings so points can easily be referenced at later stages.

Organizing Your Ideas Developing an outline for your project is one of the most important steps in the writing process. Not only will it help you get organized, but it also helps to set up a timeline and structure that can be followed while working on each section. Additionally, creating an outline allows you to brainstorm ideas related to your topic and decide which points are worth exploring further during research. When crafting an outline, two main elements must be taken into account: the type of paper being written (research paper or report) as well as its purpose (informative or persuasive). Depending on whether a student is tasked with producing a research paper or report for their assignment, they should tailor their outlining approach accordingly. Research papers typically include more detailed information compared to reports because they explore topics from different angles and require greater analysis from the author’s end; whereas reports focus mainly on summarising collected data rather than drawing conclusions about them.

When writing a research paper, you are creating something that is meant to be read and understood by an audience. It’s important to structure the body of your work in such a way as to make it easier for readers to follow along with the information being presented. The same holds true when structuring reports.

• Research Paper:

When putting together your research paper, create clear and concise points which explain why or how certain things occur within the subject material being discussed. Additionally, try including sources from credible authors who have conducted similar studies on this topic for added credibility. Finally, use subheadings throughout each section of your essay so that readers can easily move between topics without having to re-read previous paragraphs or pages.

Correct Citation Practices for Reports and Research Papers

Having the correct citation practices in place is essential to any report or research paper. Properly citing sources helps ensure accuracy of information, provides readers with further resources for additional context, and helps to protect you from plagiarism. To create effective citations, there are a few key steps that should be followed.

The first step is understanding the difference between reports and research papers – as each type will have different requirements when it comes to citation techniques. A report is an organized collection of facts related to a certain topic; these types of documents usually do not require citations but still need accurate documentation if needed information came from another source (such as books or articles). On the other hand, a research paper requires more than just listing facts – it requires critical analysis which means citations must be used throughout in order reference work done by other authors. When creating citations within this kind of document its important they follow whatever format has been specified (e.g., APA style).

• (Italicize) Report: An organized collection of facts relating to a certain topic.
• (Bold) Research Paper: Requires critical analysis and needs references throughout using an appropriate citation style such as APA.

The process of finalizing, editing and publishing a completed project can be overwhelming but also highly rewarding. Once you have achieved the desired results from your hard work and research, it’s time to bring all the pieces together for presentation to an audience.

It is important to note that there are different approaches when finalizing projects depending on whether it is a report or a research paper. Reports typically involve summarizing findings in easy-to-understand language, while research papers may require more depth as well as citing sources throughout the document.

• When finalizing reports:

Ensure data accuracy by verifying facts before presenting them; make sure content is concisely written with clarity; review any visuals included in order to ensure they accurately portray ideas being discussed; proofread multiple times before sharing information with colleagues or readership at large.

• When finalizing research papers:

Perform extensive literature reviews on topics related to main argument(s) made within paper; include citations where appropriate according to chosen formatting style guidelines (APA, MLA etc); double check if any interviews conducted during course of investigation need additional context added prior to submission/publication; use own voice throughout text but remain objective when making statements about other scholars’ works.

In conclusion, both research papers and reports offer distinct advantages. While it may be difficult to definitively say which type of writing is better overall, the right one for a given situation can depend on an individual’s needs or interests.

Research papers are beneficial when trying to dive deeply into any given topic. They often involve extensive research from outside sources as well as original analysis by the author. Additionally, they can also provide valuable perspectives that help readers gain new insights about their subject matter in a unique way.

On the other hand, reports present information in a more straightforward manner with fewer details than what’s found in research papers but still enough substance to make them useful for decision-making processes or problem solving tasks where precise facts need to be presented quickly and accurately. They tend to focus more on summaries rather than interpretations while avoiding excessive technical jargon so they remain accessible even if readers don’t have expert knowledge of the subject being discussed.

• It’s clear that each form of writing has its own set of benefits

, making them both essential components of scholarly communication no matter what field you specialize in!

English: In conclusion, the difference between a research paper and a report is of great significance. Research papers require more in-depth exploration into the subject matter while reports are typically summaries or reviews of relevant information on an issue. It is important to recognize this distinction when approaching any writing assignment that may require either format. By understanding what constitutes each type of document, students can develop their skills in both areas as well as become better equipped to tackle challenging academic tasks with confidence.

The Differences in a Research Report and Research Paper

Derek m. kwait.

When writing a paper, maybe the only thing more daunting than actually writing it is deciding what you're even supposed to be writing about. Research reports, research papers...it gets confusing. They are actually not the same thing, and knowing the difference between them will save you time and frustration, help you stay on-target and ultimately help you get the highest possible grade.

• Defining Research
• What is a Research Report?
• What is a Research Paper?
• A Word of Caution

1 Defining Research

According to Webster's Dictionary, research can be a "careful or diligent search," a "studious inquiry or examination... aimed at the discovery and interpretation of facts...in the light of new facts, or practical application of such new or revised theories or laws" or "the collecting of information about a particular subject."

While research reports and research papers both involve much of the first definition, a research report is more concerned with the second, and a research paper with the third.

2 What is a Research Report?

A research report is a paper reporting research that has already been conducted. As such, it is used primarily in the sciences to tell other scientists (or your instructor) about the process, findings and significance of your experiment.

According to a guide prepared by the American Chemical Society, a good research report of any kind should be organized in a way that parallels the method of scientific reasoning. The usual parts of this report are Title, Abstract, Introduction, Experimental Details or Theoretical Analysis, Results, Discussion, Conclusions and Summary, then References.

3 What is a Research Paper?

A research paper, on the other hand, is the research itself. In other words, a research paper typically presents quotes or information from books or scholarly papers or even movies, then analyzes them to reach some sort of conclusion. It does not report on an objective, reproducible experiment done elsewhere but instead focuses on establishing the author's thesis and arguing in favor of it. Research papers are usually used in the humanities. The format for a good research paper includes an introductory paragraph, two or three body paragraphs and a conclusion.

4 A Word of Caution

This explanation covers how these terms are typically used; there is no universally agreed upon definition of either term. Sometimes an instructor will assign a research report when he really meant a research paper or vice versa. You can usually tell what is required by what kind of class it is and what the instructor says he wants (for example, if a laboratory experiment is involved, chances are a research report is required) but if you are really unsure, ask.

A research report is one big argument about how and why you came up with your conclusions. To make it a convincing argument, a typical guiding structure has developed. In the different chapters, there are distinct issues that need to be addressed to explain to the reader why your conclusions are valid. The governing principle for writing the report is full disclosure: to explain everything and ensure replicability by another researcher.

Difference Between Research Paper and Research Report

Research Paper Definition

The research paper is, in fact, the complete & careful exploration of some specific topic or issue and reaching the results by interpreting the facts. In the research paper , the author writes about all the realistic implications of the research and its uses in the real scenario.

Research Report Definition

The research report is, in fact, a totally different piece of document that encloses the information regarding your research that what kind of investigation has been conducted in your research paper and for what purpose & in which circumstances you have conducted that research.

Research Paper and Research Report Comparison

Major Differences Between the Research Paper and Research Report

• By reading the definition only, it is easily recognized able fact that research paper represents the whole research process; on the other hand research report actually represents the concise overview and description about the complete research paper .
• Besides the definition of both, the main difference between a research paper and research report can be easily recognized only by having an overview of its complete format . Research paper encloses more chapters than the research report as a complete document. A fine research paper starts with a general introduction of the topic, and then includes a literature review of the other researchers regarding the same topic, a methodology that how you are going to do that research, results, and interpretation of the figures presented in the results. Most effective and thorough researches also narrate the importance of the research, implications and also the shortfalls of your research as well. Contrary to it, the research report cannot explain too much data about the research. Its main purpose is to enclose the course of action, results, and significance of the specific research papers which is to be discussed.
• From the above point discussed, it becomes obvious that research paper is a lengthy document because it encloses more chapters than that of the research report. Contrary to it the research report is the summarised overview of the important points of a specific research paper.
• Research paper in its literature section reviews the ideas and analysis of other researchers who already have done work on the same topic but may be in the different scenario. On the other hand, research report cannot discuss the research or investigations of other researchers but it only explains the procedure, conclusion, and importance of a specific research paper.
• The research paper can present the citations and quotations from other author’s papers along with their references or it can also narrate the ideas presented in books or movies about that topic or research in order to support your own research. However, the research report cannot narrate any kind of supportive material but only about the specifications and findings of your research work.
• Research paper and research report both are different from each other because the main purpose of both documents varies from each other. The main purpose of the research paper is to convince the readers that variables discussed in the specific research have some sort of relationship with each other and to persuade effectively writer have to quote previous researches with the same kind of experimentation or research done. On the other hand, the purpose of the research report is to provide information only. The research report provides the summarise information about the research being done; it can never be used to convince about any argument.
• Another distinction between both of them is that research paper will be based on a question or a query. Main focus of the author of the research paper will be to address the query which is stated as question or ambiguity in the start of the research paper. All efforts of the author will be inclined to provide the logic to the given or anticipated relation between two or more variables. On the other hand, the research report can never address any question or query. It is developed just to recap the important details of the targeted research paper.
• Moreover, the research report is focused to scrutinize and infer from given information. It involves arguments & logics along with gathering data. In contrast to it, the research report doesn’t need to involve any argument, analysis or interpretation of the results.
• Last but not the least research paper is a document that will be helpful in bringing distinctive and unique knowledge at the end of the research. Because research done in it is necessary to be conducted in different scenario or experimentation with a new combination of variables but research report is never inclined to do the same, It can never bring any new idea or knowledge in any case.

Characteristics of a Good Research Paper and Research Report

It has become very clear from all the above discussion that research paper and research report, both are a very different document from each other. But another fact is that there are some qualities and characteristics that may be common in both and all these qualities must be there in both documents to make them meaningful and worthy for reading.

• All the information given in the script should be based on facts only. No information should be imaginary or doubtful in any manner. Moreover, the information provided quotations or any research done by other researchers being quoted in the research paper should be provided with proofs and proper references.
• Language used for writing both types of documents must be clear and easy to understand. Use of jargons is strictly prohibited. Moreover, technical words must be used if necessary because more use of technical words will make it difficult for the reader to maintain attention in reading the whole paper. Easy and clear wording will make it more reader-friendly and understandable.
• It is also very necessary that document developed must be free of errors and there must be no duplication of any information in a single document. Duplication of information will directly lead to the decline in the interest of the reader & he will stop reading that document. Moreover, errors and doubtful information will decline the worth of the paper as well as the writer.
• The format of the research should be well prepared and its structure must be according to requirements. Otherwise, the document will lose its authenticity in the real sense.
• The manuscript developed, whether the research paper or research report must be oriented towards the result. Procedure, survey, and methodology every step should be inclined towards factual and clear results. If the results are ambiguous until the end, the whole effort of writing the document will be devastated. Moreover, each and every line is written should maintain an ethical reporting style in itself.

These qualities must be there in both documents in order to maintain the quality of the work and enhance the understanding of the manuscript for the readers. Any document, whether Research paper or research report must have these qualities, to attract the attention of the reader and make them read & understand the complete manuscript till the end.

Importance of understanding the differences between the research paper and Research Report

It is really necessary to understand the differences between the research paper and research report both. Because commonly these terms may be confused if asked generally but both types of documents have very different formats and designed to serve very different purposes. As research paper is a complete document in which each and every step of exploring a specific issue is documented along with guidance & support from the previous researches which are properly cited and referenced. On the other hand, the research report doesn’t have any concern with other researches, but it is restricted to give a concise summary of a specific research only. No other previous research is being discussed in the research report. So understanding and learning about the differences and characteristics of a good research paper and a research report will really contribute to add in the worth of the research.

A research paper is a primary source ...that is, it reports the methods and results of an original study performed by the authors . The kind of study may vary (it could have been an experiment, survey, interview, etc.), but in all cases, raw data have been collected and analyzed by the authors , and conclusions drawn from the results of that analysis.

Research papers follow a particular format.  Look for:

• A brief introduction will often include a review of the existing literature on the topic studied, and explain the rationale of the author's study.  This is important because it demonstrates that the authors are aware of existing studies, and are planning to contribute to this existing body of research in a meaningful way (that is, they're not just doing what others have already done).
• A methods section, where authors describe how they collected and analyzed data.  Statistical analyses are included.  This section is quite detailed, as it's important that other researchers be able to verify and/or replicate these methods.
• A results section describes the outcomes of the data analysis.  Charts and graphs illustrating the results are typically included.
• In the discussion , authors will explain their interpretation of their results and theorize on their importance to existing and future research.
• References or works cited are always included.  These are the articles and books that the authors drew upon to plan their study and to support their discussion.

You can use the library's article databases to search for research articles:

• A research article will nearly always be published in a peer-reviewed journal; click here for instructions on limiting your searches to peer-reviewed articles.  
• If you have a particular type of study in mind, you can include keywords to describe it in your search .  For instance, if you would like to see studies that used surveys to collect data, you can add "survey" to your topic in the database's search box. See this example search in our EBSCO databases: " bullying and survey ".   
• Several of our databases have special limiting options that allow you to select specific methodologies.  See, for instance, the " Methodology " box in ProQuest's PsycARTICLES Advanced Search (scroll down a bit to see it).  It includes options like "Empirical Study" and "Qualitative Study", among many others.  

A review article is a secondary source ...it is written about other articles, and does not report original research of its own.  Review articles are very important, as they draw upon the articles that they review to suggest new research directions, to strengthen support for existing theories and/or identify patterns among exising research studies.  For student researchers, review articles provide a great overview of the existing literature on a topic.    If you find a literature review that fits your topic, take a look at its references/works cited list for leads on other relevant articles and books!

Research Report or Research Paper?

May 7, 2013 by Paige Hudson

The term research report and research paper are often used interchangeably. Although both of these assignments require research, they do differ in several ways. In a nutshell, the student writing a research report does some research and churns out facts, while the student writing the research paper analyzes a topic and forms an opinion.

What is a Research Report?

A research report is basically a summary of what the student has learned through their exploration of a topic in books, encyclopedias or the Internet.  The student will read the desired material, such as several non-fiction books on a specific subject matter, and organize the information. Then, they will summarize what they have learned in a well-thought out manner.

These reports should take anywhere from a week to a month to complete. The 3 to 5 paragraphs of the report should be written in an informational tone, devoid of opinion. It should be concise and to the point. For the research report, the student is basically delving into a topic, organizing the material he has found and sharing what he has learned in his own words.

What is a Research Paper?

On the other hand, the research paper contains the student’s analysis and opinion of a subject. He will still do a fair amount of research and his paper should still include some summary information. However, the writer will also offer his thoughts on what he has learned, and he will use quotes and authoritative opinions to back up his claims. This means that the student will also need to use some form of citation to show from where their quotes and support material have come, which will add to the complexity of this assignment.

These papers should take anywhere from 6 weeks to several months to complete.  A research paper must include a thesis statement which causes the student to form and defend an opinion about the material. The completed paper should be clear, comprehensive and at least 6 to 8 pages in length. It should touch on why he chose the topic and how it affects the writer as well as thoroughly explain what he has found out about the subject.

So, should you assign a research report or research paper to your student?

I personally recommend beginning to assign mini-research reports during the late elementary years, once the student’s reading and writing skills are firmly in place. As the student progresses, you can add to the length requirements of the research report, increase the frequency of the assignment or advance the complexity of the material being studied.

Research papers should be reserved for high school and above, as the student’s brain needs time to develop the skills necessary to write this type of assignment. However, around 7th and 8th grade, you can also assign a hybrid research project. The hybrid project will include all the components of a research report, but will add in a page or so where the student explains how the material affected him. This type of paper will ease the student into writing the more complex research paper.

So, far in our homeschool, we have done several mini-research papers as a part of our science and history studies. I call them “mini” because they have only been 1 to 2 pages in length and have taken a week or two to complete. As we dig further into the middle school years, I plan on increasing the difficulty and length of these assignments, so that by the time high school hits, we are ready to begin to tackle our first research paper!

Literature Review vs Research Paper: What’s the Difference?

by  Antony W

January 8, 2023

This is a complete student’s guide to understanding literature review vs research paper.

We’ll teach you what they’re, explain why they’re important, state the difference between the two, and link you to our comprehensive guide on how to write them.

Literature Review Writing Help

Writing a literature review for a thesis, a research paper, or as a standalone assignment takes time. Much of your time will go into research, not to mention you have other assignments to complete. 

If you find writing in college or university overwhelming, get in touch with our literature review writers for hire at 25% discounts and enjoy the flexibility and convenience that comes with professional writing help. We’ll help you do everything, from research and outlining to custom writing and proofreading.

What is a Literature Review?

A literature review is a secondary source of information that provides an overview of existing knowledge, which you can use to identify gaps or flaws in existing research. In literature review writing, students have to find and read existing publications such as journal articles, analyze the information, and then state their findings.

Credit: Pubrica

You’ll write a literature review to demonstrate your understanding on the topic, show gaps in existing research, and develop an effective methodology and a theoretical framework for your research project.

Your instructor may ask you to write a literature review as a standalone assignment. Even if that’s the case, the rules for writing a review paper don’t change.

In other words, you’ll still focus on evaluating the current research and find gaps around the topic.

Types of Literature Reviews

There are three types of review papers and they’re a follows:

 1. Meta-analysis

In meta-analysis review paper, you combine and compare answers from already published studies on a given subject.

2. Narrative Review

A narrative review paper looks into existing information or research already conducted on a given topic.

3. Systematic Review

You need to do three things if asked to write a systematic review paper.

First, read and understand the question asked. Second, look into research already conducted on the topic. Third, search for the answer to the question from the established research you just read.

What’s a Research Paper?

A research paper is an assignment in which you present your own argument, evaluation, or interpretation of an issue based on independent research.

In a research paper project, you’ll draw some conclusions from what experts have already done, find gaps in their studies, and then draw your own conclusions.

While a research paper is like an academic essay, it tends to be longer and more detailed.

Since they require extended research and attention to details, research papers can take a lot of time to write.

If well researched, your research paper can demonstrate your knowledge about a topic, your ability to engage with multiple sources, and your willingness to contribute original thoughts to an ongoing debate.

Types of Research Papers

 There are two types of research papers and they’re as follows:

 1. Analytical Research Papers

 Similar to analytical essay , and usually in the form of a question, an analytical research paper looks at an issue from a neutral point and gives a clear analysis of the issue.

Your goal is to make the reader understand both sides of the issue in question and leave it to them to decide what side of the analysis to accept.

Unlike an argumentative research paper, an analytical research paper doesn’t include counterarguments. And you can only draw your conclusion based on the information stretched out all through the analysis.

2. Argumentative Research Papers

In an argumentative research paper, you state the subject under study, look into both sides of an issue, pick a stance, and then use solid evidence and objective reasons to defend your position.

In   argumentative writing, your goal isn’t to persuade your audience to take an action. 

Rather, it’s to convince them that your position on the research question is more accurate than the opposing point of views.

Regardless of the type of research paper that you write, you’ll have to follow the standard outline for the assignment to be acceptable for review and marking.

Also, all research paper, regardless of the research question under investigation must include a literature review.

Literature Review vs Research Paper

The table below shows the differences between a literature review (review paper) and a research paper. 

Frequently Asked Questions

1. is there a literature review in a research paper.

A research paper assignment must include a literature review immediately after the introduction chapter.

The chapter is significant because your research work would otherwise be incomplete without knowledge of existing literature. 

2. How Many Literature Review Should Be in Research Paper?

Your research paper  should have only one literature review. Make sure you write the review based on the instructions from your teacher.

Before you start, check the required length, number of sources to summarize, and the format to use. Doing so will help you score top grades for the assignment. 

3. What is the Difference Between Research and Literature?

Whereas literature focuses on gathering, reading, and summarizing information on already established studies, original research involves coming up with new concepts, theories, and ideas that might fill existing gaps in the available literature.

4. How Long is a Literature Review?

How long a literature review should be will depend on several factors, including the level of education, the length of the assignment, the target audience, and the purpose of the review.

For example, a 150-page dissertation can have a literature review of 40 pages on average.

Make sure you talk to your instructor to determine the required length of the assignment.

5. How Does a Literature Review Look Like?

Your literature review shouldn’t be a focus on original research or new information. Rather, it should give a clear overview of the already existing work on the selected topic.

The information to review can come from various sources, including scholarly journal articles , government reports, credible websites, and academic-based books.

Difference Between Thesis and Research Paper

On the other hand, a research paper is analytical, argumentative and interpretative in nature. It involves the pursuit of knowledge and intelligent analysis of the information collected. It contains the idea of the author, often supported by expert opinions, research and information available in this regard.

Whether you are writing a thesis or research paper, they are equally challenging and take a lot of time to prepare. In this post, we will update you on all the points of difference between thesis and  research paper.

Content: Thesis Vs Research Paper

• Key Elements
• Thesis Statement

How to start a research paper?

Comparison chart, what is thesis.

The thesis is a document containing the research and findings that students submit to get the professional qualification or degree . It has to be argumentative, which proposes a debatable point with which people could either agree or disagree. In short, it is a research report in writing that contains a problem which is yet to be dealt with.

In a thesis, the researcher puts forth his/her conclusion. The researcher also gives evidence in support of the conclusion.

Submission of the thesis is a mandatory requirement of a postgraduate course and PhD degree. In this, the primary focus is on the novelty of research along with the research methodology.

It is all about possibilities, by introducing several anti-thesis. Also, it ends up all the possibilities by nullifying all these anti-thesis.

Key Elements of Thesis

• Proposition : The thesis propagates an idea, hypothesis or recommendation.
• Argument : Gives reasons for accepting the proposition instead of just asserting a point of view.
• Maintenance of argument : The argument should be made cogent enough by providing suitable logic and adequate evidence.

Features of An Ideal Thesis

• An Ideal thesis is expected to add fresh knowledge to the existing theory.
• It communicates the central idea of the research in a clear and concise manner.
• An effective thesis is more than a simple statement, fact or question.
• It answers why and how questions concerned with the topic.
• To avoid confusion, it is worded carefully.
• It outlines the direction and scope of your essay.
• It gives reasons to the reader to continue reading.

What is Thesis Statement?

A thesis statement is a sentence of one line, usually written at the end of your first paragraph. It presents the argument to the reader.

It is a blueprint of your thesis that directs the writer while writing the thesis and guides the reader through it.

What is Research Paper?

Research Paper is a form of academic writing. It is prepared on the basis of the original research conducted by the author on a specific topic, along with its analysis and interpretation of the findings.

An author generally starts writing a research paper on the basis of what he knows about the topic and seeks to find out what experts know. Further, it involves thorough and systematic research on a particular subject to extract the maximum information.

In short, a research paper is a written and published report containing the results of scientific research or a review of published scientific papers. Here, the scientific research is the primary research article, while the review of a published scientific paper is the review article.

In case of the primary research article, the author of the research paper provides important information about the research. This enables the scientific community members to:

• Evaluate it
• Reproduce the experiments
• Assess the reasoning and conclusions drawn

On the other hand, a review article is written to analyze, summarize and synthesize the research carried out previously.

When a research work is published in a scientific journal, it conveys the knowledge to a larger group of people and also makes people aware of the scientific work. Research work published as a research paper passes on knowledge and information to many people. The research paper provides relevant information about the disease and the treatment options at hand .

To start writing a research paper, one should always go for a topic that is interesting and a bit challenging too. Here, the key to choosing the topic is to pick the one that you can manage. So, you could avoid such topics which are very technical or specialized and also those topics for which data is not easily available. Also, do not go for any controversial topic.

The researcher’s approach and attitude towards the topic will decide the amount of effort and enthusiasm.

Steps for writing Research Paper

The total number of pages included in a Research Paper relies upon the research topic. It may include 8 to 10 pages, which are:

• Introduction
• Review of Literature
• Methodology
• Research Analysis
• Recommendations

Key Differences Between Thesis and Research Paper

• A thesis implies an original, plagiarism-free, written academic document that acts as a final project for a university degree of a higher level. But, Research Paper is a novel, plagiarism-free long essay. It portrays the interpretation, evaluation or argument submitted by a researcher.
• The thesis acts as a final project. Whereas a research paper is a kind of research manual of journals.
• The length of the thesis is around 20,000 to 80,000 words. On the contrary, the length of the research paper is relative to the study.
• The thesis focuses on the central question or statement of an intellectual argument that entails further research. On the contrary, the research paper is concerned with proving the central argument.
• The purpose of submitting the thesis is to get the degree or professional qualification. It also presents the knowledge of the candidate in the respective field. Conversely, the aim of publishing research papers is to prove credibility and contribute knowledge in the respective field.
• While the student submits the thesis to the educational committee or panel of professors who review it. In contrast, scientists and other researchers read and review the research paper.
• Preparation and completion of thesis is always under the guidance of a supervisor. For submission of the thesis, the university assigns a supervisor to each student, under whose guidance the thesis must be completed. As against, no supervisor is appointed as a guide in case of a research paper.
• The thesis contains a broader description of the subject matter. In contrast, the research paper contains a narrow description of the subject matter.

Once the research paper is published, it increases the fellowship and job opportunities for new researchers. On the other hand, thesis writing will enable the students to get the desired degree at the end of the course they have opted.

This study aimed to evaluate the impact of APOE4 homozygosity on Alzheimer’s disease (AD) by examining its clinical, pathological and biomarker changes to see whether APOE4 homozygotes constitute a distinct, genetically determined form of AD. Data from the National Alzheimer’s Coordinating Center and five large cohorts with AD biomarkers were analyzed. The analysis included 3,297 individuals for the pathological study and 10,039 for the clinical study. Findings revealed that almost all APOE4 homozygotes exhibited AD pathology and had significantly higher levels of AD biomarkers from age 55 compared to APOE3 homozygotes. By age 65, nearly all had abnormal amyloid levels in cerebrospinal fluid, and 75% had positive amyloid scans, with the prevalence of these markers increasing with age, indicating near-full penetrance of AD biology in APOE4 homozygotes. The age of symptom onset was earlier in APOE4 homozygotes at 65.1, with a narrower 95% prediction interval than APOE3 homozygotes. The predictability of symptom onset and the sequence of biomarker changes in APOE4 homozygotes mirrored those in autosomal dominant AD and Down syndrome. However, in the dementia stage, there were no differences in amyloid or tau positron emission tomography across haplotypes, despite earlier clinical and biomarker changes. The study concludes that APOE4 homozygotes represent a genetic form of AD, suggesting the need for individualized prevention strategies, clinical trials and treatments.

As Biden and Trump seek reelection, who are the oldest – and youngest – current world leaders?

Joe Biden, at 81, is the oldest American president , a distinction he’s held since entering office at age 78. As Biden runs for reelection in 2024, he is the ninth oldest national leader in the world, according to a Pew Research Center analysis of sitting leaders in 187 United Nations member states.

Former President Donald Trump, who is running for the White House again this year, is younger than Biden. But at 77, Trump also falls among the 20 oldest world leaders when compared with those currently in power.

With current U.S. President Joe Biden and former President Donald Trump both running for reelection to the country’s highest office, Pew Research Center examined the ages of current national leaders to place the ages of Biden and Trump into a global context.

This analysis examines the ages of the current heads of government in 187 countries that are member states of the United Nations, relying on government biographies and regional news articles. It reflects the ages of national leaders – and in a few instances, acting or interim leaders – as of May 1, 2024. It excludes six UN member states for which an exact birth date of the leader could not be found: Afghanistan, Haiti, Iraq, Mali, Niger and Somalia. For each of these countries, we reached out to embassy officials in the United States but did not receive further information.

This analysis focuses mostly on heads of government as defined by a country’s political system or constitution. In some cases, we determined the national leader based on which executive has the power to appoint/dismiss the nominal head of government. In San Marino, where there are two captains regent who share power, we included data for Alessandro Rossi, as he assumed the position most recently.

This analysis also draws on Freedom House country rankings to determine whether countries are free, partly free or not free. These rankings are based on two numerical scores assigned to each country for its political rights and civil liberties.

The median age of each country’s overall population is a 2024 projection from the UN’s World Population Prospects 2022 report . The projections are based on “all available sources of data on population size and levels of fertility, mortality and international migration.”

American voters are skeptical about both candidates’ fitness for the job, according to a recent Center survey . Only about four-in-ten U.S. registered voters are extremely or very confident that Trump has the mental fitness to be president (38%), while a similar share are confident in his physical fitness (36%). Even fewer express this degree of confidence in Biden’s mental (21%) and physical (15%) fitness for the role.

Below are five key facts about the ages of current national leaders.

National leaders range in age from their mid-30s to 91. The youngest leader is Burkina Faso’s Ibrahim Traoré, who is 36. He only slightly edges out two fellow 36-year-olds, Ecuadorian President Daniel Noboa and Montenegrin Prime Minister Milojko Spajić. Only two other world leaders are in their 30s: Irish Taoiseach Simon Harris and Chilean President Gabriel Boric.

The oldest national leader is President Paul Biya of Cameroon, who was born in 1933 and took office more than 40 years ago. Biya is the only current national leader in his 90s.

The median age of current national leaders is 62, as of May 1, 2024. The largest share of global leaders today (34%) are in their 60s. Roughly a quarter (22%) are in their 50s; 19% are in their 70s; and 16% are in their 40s. Biden is among the 5% of leaders who are in their 80s.

Countries that are less free tend to have older leaders. In countries that Freedom House classifies as “not free,” the median age of the national leader is 68. That compares with 62 in countries that are classified as “partly free” and 60 in countries classified as “free.”

The United States is one of only three countries that are classified as free and have a leader age 80 or older; the other two are Ghana and Namibia. In Ghana, President Nana Akufo-Addo recently turned 80 in office. And in Namibia, 82-year-old Nangolo Mbumba took over as president earlier this year following the previous leader’s death in office at age 82.

The median age for women leaders and men leaders is the same. Among men who are world leaders, 3% are in their 30s, while no women leaders are in this age group. Yet, of the 14 women leaders currently in power, 29% are in their 40s, compared with 14% of leaders who are men.

Prime Minister Mette Frederiksen of Denmark is the youngest female leader at 46, followed closely by fellow 46-year-old Kaja Kallas , the prime minister of Estonia. Prime Minister Sheikh Hasina of Bangladesh is the oldest female leader at 76.

In most countries, the leader is significantly older than the median member of the population. For example, the median American is 38, according to UN population projections for 2024, while Biden is more than twice as old. In fact, the only countries that have a leader who is younger than the median resident of the country are Montenegro, Ireland and Italy. Andorran Prime Minister Xavier Espot Zamora, at 44, is the same age as the median Andorran resident. 

In general, countries that Freedom House classifies as free are more likely than those classified as partly free or not free to have leaders who are closer in age to the median resident of the country.
