Chapter 11: Presenting Your Research

Writing a Research Report in American Psychological Association (APA) Style

Learning Objectives

• Identify the major sections of an APA-style research report and the basic contents of each section.
• Plan and write an effective APA-style research report.

In this section, we look at how to write an APA-style empirical research report , an article that presents the results of one or more new studies. Recall that the standard sections of an empirical research report provide a kind of outline. Here we consider each of these sections in detail, including what information it contains, how that information is formatted and organized, and tips for writing each section. At the end of this section is a sample APA-style research report that illustrates many of these principles.

Sections of a Research Report

Title page and abstract.

An APA-style research report begins with a  title page . The title is centred in the upper half of the page, with each important word capitalized. The title should clearly and concisely (in about 12 words or fewer) communicate the primary variables and research questions. This sometimes requires a main title followed by a subtitle that elaborates on the main title, in which case the main title and subtitle are separated by a colon. Here are some titles from recent issues of professional journals published by the American Psychological Association.

• Sex Differences in Coping Styles and Implications for Depressed Mood
• Effects of Aging and Divided Attention on Memory for Items and Their Contexts
• Computer-Assisted Cognitive Behavioural Therapy for Child Anxiety: Results of a Randomized Clinical Trial
• Virtual Driving and Risk Taking: Do Racing Games Increase Risk-Taking Cognitions, Affect, and Behaviour?

Below the title are the authors’ names and, on the next line, their institutional affiliation—the university or other institution where the authors worked when they conducted the research. As we have already seen, the authors are listed in an order that reflects their contribution to the research. When multiple authors have made equal contributions to the research, they often list their names alphabetically or in a randomly determined order.

In some areas of psychology, the titles of many empirical research reports are informal in a way that is perhaps best described as “cute.” They usually take the form of a play on words or a well-known expression that relates to the topic under study. Here are some examples from recent issues of the Journal Psychological Science .

• “Smells Like Clean Spirit: Nonconscious Effects of Scent on Cognition and Behavior”
• “Time Crawls: The Temporal Resolution of Infants’ Visual Attention”
• “Scent of a Woman: Men’s Testosterone Responses to Olfactory Ovulation Cues”
• “Apocalypse Soon?: Dire Messages Reduce Belief in Global Warming by Contradicting Just-World Beliefs”
• “Serial vs. Parallel Processing: Sometimes They Look Like Tweedledum and Tweedledee but They Can (and Should) Be Distinguished”
• “How Do I Love Thee? Let Me Count the Words: The Social Effects of Expressive Writing”

Individual researchers differ quite a bit in their preference for such titles. Some use them regularly, while others never use them. What might be some of the pros and cons of using cute article titles?

For articles that are being submitted for publication, the title page also includes an author note that lists the authors’ full institutional affiliations, any acknowledgments the authors wish to make to agencies that funded the research or to colleagues who commented on it, and contact information for the authors. For student papers that are not being submitted for publication—including theses—author notes are generally not necessary.

The  abstract  is a summary of the study. It is the second page of the manuscript and is headed with the word  Abstract . The first line is not indented. The abstract presents the research question, a summary of the method, the basic results, and the most important conclusions. Because the abstract is usually limited to about 200 words, it can be a challenge to write a good one.

Introduction

The  introduction  begins on the third page of the manuscript. The heading at the top of this page is the full title of the manuscript, with each important word capitalized as on the title page. The introduction includes three distinct subsections, although these are typically not identified by separate headings. The opening introduces the research question and explains why it is interesting, the literature review discusses relevant previous research, and the closing restates the research question and comments on the method used to answer it.

The Opening

The  opening , which is usually a paragraph or two in length, introduces the research question and explains why it is interesting. To capture the reader’s attention, researcher Daryl Bem recommends starting with general observations about the topic under study, expressed in ordinary language (not technical jargon)—observations that are about people and their behaviour (not about researchers or their research; Bem, 2003 [1] ). Concrete examples are often very useful here. According to Bem, this would be a poor way to begin a research report:

Festinger’s theory of cognitive dissonance received a great deal of attention during the latter part of the 20th century (p. 191)

The following would be much better:

The individual who holds two beliefs that are inconsistent with one another may feel uncomfortable. For example, the person who knows that he or she enjoys smoking but believes it to be unhealthy may experience discomfort arising from the inconsistency or disharmony between these two thoughts or cognitions. This feeling of discomfort was called cognitive dissonance by social psychologist Leon Festinger (1957), who suggested that individuals will be motivated to remove this dissonance in whatever way they can (p. 191).

After capturing the reader’s attention, the opening should go on to introduce the research question and explain why it is interesting. Will the answer fill a gap in the literature? Will it provide a test of an important theory? Does it have practical implications? Giving readers a clear sense of what the research is about and why they should care about it will motivate them to continue reading the literature review—and will help them make sense of it.

Breaking the Rules

Researcher Larry Jacoby reported several studies showing that a word that people see or hear repeatedly can seem more familiar even when they do not recall the repetitions—and that this tendency is especially pronounced among older adults. He opened his article with the following humourous anecdote:

A friend whose mother is suffering symptoms of Alzheimer’s disease (AD) tells the story of taking her mother to visit a nursing home, preliminary to her mother’s moving there. During an orientation meeting at the nursing home, the rules and regulations were explained, one of which regarded the dining room. The dining room was described as similar to a fine restaurant except that tipping was not required. The absence of tipping was a central theme in the orientation lecture, mentioned frequently to emphasize the quality of care along with the advantages of having paid in advance. At the end of the meeting, the friend’s mother was asked whether she had any questions. She replied that she only had one question: “Should I tip?” (Jacoby, 1999, p. 3)

Although both humour and personal anecdotes are generally discouraged in APA-style writing, this example is a highly effective way to start because it both engages the reader and provides an excellent real-world example of the topic under study.

The Literature Review

Immediately after the opening comes the  literature review , which describes relevant previous research on the topic and can be anywhere from several paragraphs to several pages in length. However, the literature review is not simply a list of past studies. Instead, it constitutes a kind of argument for why the research question is worth addressing. By the end of the literature review, readers should be convinced that the research question makes sense and that the present study is a logical next step in the ongoing research process.

Like any effective argument, the literature review must have some kind of structure. For example, it might begin by describing a phenomenon in a general way along with several studies that demonstrate it, then describing two or more competing theories of the phenomenon, and finally presenting a hypothesis to test one or more of the theories. Or it might describe one phenomenon, then describe another phenomenon that seems inconsistent with the first one, then propose a theory that resolves the inconsistency, and finally present a hypothesis to test that theory. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally suggest a way to test whether it does, in fact, apply to that situation.

Looking at the literature review in this way emphasizes a few things. First, it is extremely important to start with an outline of the main points that you want to make, organized in the order that you want to make them. The basic structure of your argument, then, should be apparent from the outline itself. Second, it is important to emphasize the structure of your argument in your writing. One way to do this is to begin the literature review by summarizing your argument even before you begin to make it. “In this article, I will describe two apparently contradictory phenomena, present a new theory that has the potential to resolve the apparent contradiction, and finally present a novel hypothesis to test the theory.” Another way is to open each paragraph with a sentence that summarizes the main point of the paragraph and links it to the preceding points. These opening sentences provide the “transitions” that many beginning researchers have difficulty with. Instead of beginning a paragraph by launching into a description of a previous study, such as “Williams (2004) found that…,” it is better to start by indicating something about why you are describing this particular study. Here are some simple examples:

Another example of this phenomenon comes from the work of Williams (2004).

Williams (2004) offers one explanation of this phenomenon.

An alternative perspective has been provided by Williams (2004).

We used a method based on the one used by Williams (2004).

Finally, remember that your goal is to construct an argument for why your research question is interesting and worth addressing—not necessarily why your favourite answer to it is correct. In other words, your literature review must be balanced. If you want to emphasize the generality of a phenomenon, then of course you should discuss various studies that have demonstrated it. However, if there are other studies that have failed to demonstrate it, you should discuss them too. Or if you are proposing a new theory, then of course you should discuss findings that are consistent with that theory. However, if there are other findings that are inconsistent with it, again, you should discuss them too. It is acceptable to argue that the  balance  of the research supports the existence of a phenomenon or is consistent with a theory (and that is usually the best that researchers in psychology can hope for), but it is not acceptable to  ignore contradictory evidence. Besides, a large part of what makes a research question interesting is uncertainty about its answer.

The Closing

The  closing  of the introduction—typically the final paragraph or two—usually includes two important elements. The first is a clear statement of the main research question or hypothesis. This statement tends to be more formal and precise than in the opening and is often expressed in terms of operational definitions of the key variables. The second is a brief overview of the method and some comment on its appropriateness. Here, for example, is how Darley and Latané (1968) [2] concluded the introduction to their classic article on the bystander effect:

These considerations lead to the hypothesis that the more bystanders to an emergency, the less likely, or the more slowly, any one bystander will intervene to provide aid. To test this proposition it would be necessary to create a situation in which a realistic “emergency” could plausibly occur. Each subject should also be blocked from communicating with others to prevent his getting information about their behaviour during the emergency. Finally, the experimental situation should allow for the assessment of the speed and frequency of the subjects’ reaction to the emergency. The experiment reported below attempted to fulfill these conditions. (p. 378)

Thus the introduction leads smoothly into the next major section of the article—the method section.

The  method section  is where you describe how you conducted your study. An important principle for writing a method section is that it should be clear and detailed enough that other researchers could replicate the study by following your “recipe.” This means that it must describe all the important elements of the study—basic demographic characteristics of the participants, how they were recruited, whether they were randomly assigned, how the variables were manipulated or measured, how counterbalancing was accomplished, and so on. At the same time, it should avoid irrelevant details such as the fact that the study was conducted in Classroom 37B of the Industrial Technology Building or that the questionnaire was double-sided and completed using pencils.

The method section begins immediately after the introduction ends with the heading “Method” (not “Methods”) centred on the page. Immediately after this is the subheading “Participants,” left justified and in italics. The participants subsection indicates how many participants there were, the number of women and men, some indication of their age, other demographics that may be relevant to the study, and how they were recruited, including any incentives given for participation.

After the participants section, the structure can vary a bit. Figure 11.1 shows three common approaches. In the first, the participants section is followed by a design and procedure subsection, which describes the rest of the method. This works well for methods that are relatively simple and can be described adequately in a few paragraphs. In the second approach, the participants section is followed by separate design and procedure subsections. This works well when both the design and the procedure are relatively complicated and each requires multiple paragraphs.

What is the difference between design and procedure? The design of a study is its overall structure. What were the independent and dependent variables? Was the independent variable manipulated, and if so, was it manipulated between or within subjects? How were the variables operationally defined? The procedure is how the study was carried out. It often works well to describe the procedure in terms of what the participants did rather than what the researchers did. For example, the participants gave their informed consent, read a set of instructions, completed a block of four practice trials, completed a block of 20 test trials, completed two questionnaires, and were debriefed and excused.

In the third basic way to organize a method section, the participants subsection is followed by a materials subsection before the design and procedure subsections. This works well when there are complicated materials to describe. This might mean multiple questionnaires, written vignettes that participants read and respond to, perceptual stimuli, and so on. The heading of this subsection can be modified to reflect its content. Instead of “Materials,” it can be “Questionnaires,” “Stimuli,” and so on.

The  results section  is where you present the main results of the study, including the results of the statistical analyses. Although it does not include the raw data—individual participants’ responses or scores—researchers should save their raw data and make them available to other researchers who request them. Several journals now encourage the open sharing of raw data online.

Although there are no standard subsections, it is still important for the results section to be logically organized. Typically it begins with certain preliminary issues. One is whether any participants or responses were excluded from the analyses and why. The rationale for excluding data should be described clearly so that other researchers can decide whether it is appropriate. A second preliminary issue is how multiple responses were combined to produce the primary variables in the analyses. For example, if participants rated the attractiveness of 20 stimulus people, you might have to explain that you began by computing the mean attractiveness rating for each participant. Or if they recalled as many items as they could from study list of 20 words, did you count the number correctly recalled, compute the percentage correctly recalled, or perhaps compute the number correct minus the number incorrect? A third preliminary issue is the reliability of the measures. This is where you would present test-retest correlations, Cronbach’s α, or other statistics to show that the measures are consistent across time and across items. A final preliminary issue is whether the manipulation was successful. This is where you would report the results of any manipulation checks.

The results section should then tackle the primary research questions, one at a time. Again, there should be a clear organization. One approach would be to answer the most general questions and then proceed to answer more specific ones. Another would be to answer the main question first and then to answer secondary ones. Regardless, Bem (2003) [3] suggests the following basic structure for discussing each new result:

• Remind the reader of the research question.
• Give the answer to the research question in words.
• Present the relevant statistics.
• Qualify the answer if necessary.
• Summarize the result.

Notice that only Step 3 necessarily involves numbers. The rest of the steps involve presenting the research question and the answer to it in words. In fact, the basic results should be clear even to a reader who skips over the numbers.

The  discussion  is the last major section of the research report. Discussions usually consist of some combination of the following elements:

• Summary of the research
• Theoretical implications
• Practical implications
• Limitations
• Suggestions for future research

The discussion typically begins with a summary of the study that provides a clear answer to the research question. In a short report with a single study, this might require no more than a sentence. In a longer report with multiple studies, it might require a paragraph or even two. The summary is often followed by a discussion of the theoretical implications of the research. Do the results provide support for any existing theories? If not, how  can  they be explained? Although you do not have to provide a definitive explanation or detailed theory for your results, you at least need to outline one or more possible explanations. In applied research—and often in basic research—there is also some discussion of the practical implications of the research. How can the results be used, and by whom, to accomplish some real-world goal?

The theoretical and practical implications are often followed by a discussion of the study’s limitations. Perhaps there are problems with its internal or external validity. Perhaps the manipulation was not very effective or the measures not very reliable. Perhaps there is some evidence that participants did not fully understand their task or that they were suspicious of the intent of the researchers. Now is the time to discuss these issues and how they might have affected the results. But do not overdo it. All studies have limitations, and most readers will understand that a different sample or different measures might have produced different results. Unless there is good reason to think they  would have, however, there is no reason to mention these routine issues. Instead, pick two or three limitations that seem like they could have influenced the results, explain how they could have influenced the results, and suggest ways to deal with them.

Most discussions end with some suggestions for future research. If the study did not satisfactorily answer the original research question, what will it take to do so? What  new  research questions has the study raised? This part of the discussion, however, is not just a list of new questions. It is a discussion of two or three of the most important unresolved issues. This means identifying and clarifying each question, suggesting some alternative answers, and even suggesting ways they could be studied.

Finally, some researchers are quite good at ending their articles with a sweeping or thought-provoking conclusion. Darley and Latané (1968) [4] , for example, ended their article on the bystander effect by discussing the idea that whether people help others may depend more on the situation than on their personalities. Their final sentence is, “If people understand the situational forces that can make them hesitate to intervene, they may better overcome them” (p. 383). However, this kind of ending can be difficult to pull off. It can sound overreaching or just banal and end up detracting from the overall impact of the article. It is often better simply to end when you have made your final point (although you should avoid ending on a limitation).

The references section begins on a new page with the heading “References” centred at the top of the page. All references cited in the text are then listed in the format presented earlier. They are listed alphabetically by the last name of the first author. If two sources have the same first author, they are listed alphabetically by the last name of the second author. If all the authors are the same, then they are listed chronologically by the year of publication. Everything in the reference list is double-spaced both within and between references.

Appendices, Tables, and Figures

Appendices, tables, and figures come after the references. An  appendix  is appropriate for supplemental material that would interrupt the flow of the research report if it were presented within any of the major sections. An appendix could be used to present lists of stimulus words, questionnaire items, detailed descriptions of special equipment or unusual statistical analyses, or references to the studies that are included in a meta-analysis. Each appendix begins on a new page. If there is only one, the heading is “Appendix,” centred at the top of the page. If there is more than one, the headings are “Appendix A,” “Appendix B,” and so on, and they appear in the order they were first mentioned in the text of the report.

After any appendices come tables and then figures. Tables and figures are both used to present results. Figures can also be used to illustrate theories (e.g., in the form of a flowchart), display stimuli, outline procedures, and present many other kinds of information. Each table and figure appears on its own page. Tables are numbered in the order that they are first mentioned in the text (“Table 1,” “Table 2,” and so on). Figures are numbered the same way (“Figure 1,” “Figure 2,” and so on). A brief explanatory title, with the important words capitalized, appears above each table. Each figure is given a brief explanatory caption, where (aside from proper nouns or names) only the first word of each sentence is capitalized. More details on preparing APA-style tables and figures are presented later in the book.

Sample APA-Style Research Report

Figures 11.2, 11.3, 11.4, and 11.5 show some sample pages from an APA-style empirical research report originally written by undergraduate student Tomoe Suyama at California State University, Fresno. The main purpose of these figures is to illustrate the basic organization and formatting of an APA-style empirical research report, although many high-level and low-level style conventions can be seen here too.

Key Takeaways

• An APA-style empirical research report consists of several standard sections. The main ones are the abstract, introduction, method, results, discussion, and references.
• The introduction consists of an opening that presents the research question, a literature review that describes previous research on the topic, and a closing that restates the research question and comments on the method. The literature review constitutes an argument for why the current study is worth doing.
• The method section describes the method in enough detail that another researcher could replicate the study. At a minimum, it consists of a participants subsection and a design and procedure subsection.
• The results section describes the results in an organized fashion. Each primary result is presented in terms of statistical results but also explained in words.
• The discussion typically summarizes the study, discusses theoretical and practical implications and limitations of the study, and offers suggestions for further research.
• Practice: Look through an issue of a general interest professional journal (e.g.,  Psychological Science ). Read the opening of the first five articles and rate the effectiveness of each one from 1 ( very ineffective ) to 5 ( very effective ). Write a sentence or two explaining each rating.
• Practice: Find a recent article in a professional journal and identify where the opening, literature review, and closing of the introduction begin and end.
• Practice: Find a recent article in a professional journal and highlight in a different colour each of the following elements in the discussion: summary, theoretical implications, practical implications, limitations, and suggestions for future research.

Long Descriptions

Figure 11.1 long description: Table showing three ways of organizing an APA-style method section.

In the simple method, there are two subheadings: “Participants” (which might begin “The participants were…”) and “Design and procedure” (which might begin “There were three conditions…”).

In the typical method, there are three subheadings: “Participants” (“The participants were…”), “Design” (“There were three conditions…”), and “Procedure” (“Participants viewed each stimulus on the computer screen…”).

In the complex method, there are four subheadings: “Participants” (“The participants were…”), “Materials” (“The stimuli were…”), “Design” (“There were three conditions…”), and “Procedure” (“Participants viewed each stimulus on the computer screen…”). [Return to Figure 11.1]

Research Report

Definition:

Research Report is a written document that presents the results of a research project or study, including the research question, methodology, results, and conclusions, in a clear and objective manner.

The purpose of a research report is to communicate the findings of the research to the intended audience, which could be other researchers, stakeholders, or the general public.

Components of Research Report

Components of Research Report are as follows:

Introduction

The introduction sets the stage for the research report and provides a brief overview of the research question or problem being investigated. It should include a clear statement of the purpose of the study and its significance or relevance to the field of research. It may also provide background information or a literature review to help contextualize the research.

Literature Review

The literature review provides a critical analysis and synthesis of the existing research and scholarship relevant to the research question or problem. It should identify the gaps, inconsistencies, and contradictions in the literature and show how the current study addresses these issues. The literature review also establishes the theoretical framework or conceptual model that guides the research.

Methodology

The methodology section describes the research design, methods, and procedures used to collect and analyze data. It should include information on the sample or participants, data collection instruments, data collection procedures, and data analysis techniques. The methodology should be clear and detailed enough to allow other researchers to replicate the study.

The results section presents the findings of the study in a clear and objective manner. It should provide a detailed description of the data and statistics used to answer the research question or test the hypothesis. Tables, graphs, and figures may be included to help visualize the data and illustrate the key findings.

The discussion section interprets the results of the study and explains their significance or relevance to the research question or problem. It should also compare the current findings with those of previous studies and identify the implications for future research or practice. The discussion should be based on the results presented in the previous section and should avoid speculation or unfounded conclusions.

The conclusion summarizes the key findings of the study and restates the main argument or thesis presented in the introduction. It should also provide a brief overview of the contributions of the study to the field of research and the implications for practice or policy.

The references section lists all the sources cited in the research report, following a specific citation style, such as APA or MLA.

The appendices section includes any additional material, such as data tables, figures, or instruments used in the study, that could not be included in the main text due to space limitations.

Types of Research Report

Types of Research Report are as follows:

Thesis is a type of research report. A thesis is a long-form research document that presents the findings and conclusions of an original research study conducted by a student as part of a graduate or postgraduate program. It is typically written by a student pursuing a higher degree, such as a Master’s or Doctoral degree, although it can also be written by researchers or scholars in other fields.

Research Paper

Research paper is a type of research report. A research paper is a document that presents the results of a research study or investigation. Research papers can be written in a variety of fields, including science, social science, humanities, and business. They typically follow a standard format that includes an introduction, literature review, methodology, results, discussion, and conclusion sections.

Technical Report

A technical report is a detailed report that provides information about a specific technical or scientific problem or project. Technical reports are often used in engineering, science, and other technical fields to document research and development work.

Progress Report

A progress report provides an update on the progress of a research project or program over a specific period of time. Progress reports are typically used to communicate the status of a project to stakeholders, funders, or project managers.

Feasibility Report

A feasibility report assesses the feasibility of a proposed project or plan, providing an analysis of the potential risks, benefits, and costs associated with the project. Feasibility reports are often used in business, engineering, and other fields to determine the viability of a project before it is undertaken.

Field Report

A field report documents observations and findings from fieldwork, which is research conducted in the natural environment or setting. Field reports are often used in anthropology, ecology, and other social and natural sciences.

Experimental Report

An experimental report documents the results of a scientific experiment, including the hypothesis, methods, results, and conclusions. Experimental reports are often used in biology, chemistry, and other sciences to communicate the results of laboratory experiments.

Case Study Report

A case study report provides an in-depth analysis of a specific case or situation, often used in psychology, social work, and other fields to document and understand complex cases or phenomena.

Literature Review Report

A literature review report synthesizes and summarizes existing research on a specific topic, providing an overview of the current state of knowledge on the subject. Literature review reports are often used in social sciences, education, and other fields to identify gaps in the literature and guide future research.

Research Report Example

Following is a Research Report Example sample for Students:

Title: The Impact of Social Media on Academic Performance among High School Students

This study aims to investigate the relationship between social media use and academic performance among high school students. The study utilized a quantitative research design, which involved a survey questionnaire administered to a sample of 200 high school students. The findings indicate that there is a negative correlation between social media use and academic performance, suggesting that excessive social media use can lead to poor academic performance among high school students. The results of this study have important implications for educators, parents, and policymakers, as they highlight the need for strategies that can help students balance their social media use and academic responsibilities.

Introduction:

Social media has become an integral part of the lives of high school students. With the widespread use of social media platforms such as Facebook, Twitter, Instagram, and Snapchat, students can connect with friends, share photos and videos, and engage in discussions on a range of topics. While social media offers many benefits, concerns have been raised about its impact on academic performance. Many studies have found a negative correlation between social media use and academic performance among high school students (Kirschner & Karpinski, 2010; Paul, Baker, & Cochran, 2012).

Given the growing importance of social media in the lives of high school students, it is important to investigate its impact on academic performance. This study aims to address this gap by examining the relationship between social media use and academic performance among high school students.

Methodology:

The study utilized a quantitative research design, which involved a survey questionnaire administered to a sample of 200 high school students. The questionnaire was developed based on previous studies and was designed to measure the frequency and duration of social media use, as well as academic performance.

The participants were selected using a convenience sampling technique, and the survey questionnaire was distributed in the classroom during regular school hours. The data collected were analyzed using descriptive statistics and correlation analysis.

The findings indicate that the majority of high school students use social media platforms on a daily basis, with Facebook being the most popular platform. The results also show a negative correlation between social media use and academic performance, suggesting that excessive social media use can lead to poor academic performance among high school students.

Discussion:

The results of this study have important implications for educators, parents, and policymakers. The negative correlation between social media use and academic performance suggests that strategies should be put in place to help students balance their social media use and academic responsibilities. For example, educators could incorporate social media into their teaching strategies to engage students and enhance learning. Parents could limit their children’s social media use and encourage them to prioritize their academic responsibilities. Policymakers could develop guidelines and policies to regulate social media use among high school students.

Conclusion:

In conclusion, this study provides evidence of the negative impact of social media on academic performance among high school students. The findings highlight the need for strategies that can help students balance their social media use and academic responsibilities. Further research is needed to explore the specific mechanisms by which social media use affects academic performance and to develop effective strategies for addressing this issue.

Limitations:

One limitation of this study is the use of convenience sampling, which limits the generalizability of the findings to other populations. Future studies should use random sampling techniques to increase the representativeness of the sample. Another limitation is the use of self-reported measures, which may be subject to social desirability bias. Future studies could use objective measures of social media use and academic performance, such as tracking software and school records.

Implications:

The findings of this study have important implications for educators, parents, and policymakers. Educators could incorporate social media into their teaching strategies to engage students and enhance learning. For example, teachers could use social media platforms to share relevant educational resources and facilitate online discussions. Parents could limit their children’s social media use and encourage them to prioritize their academic responsibilities. They could also engage in open communication with their children to understand their social media use and its impact on their academic performance. Policymakers could develop guidelines and policies to regulate social media use among high school students. For example, schools could implement social media policies that restrict access during class time and encourage responsible use.

Applications of Research Report

Research reports have many applications, including:

• Communicating research findings: The primary application of a research report is to communicate the results of a study to other researchers, stakeholders, or the general public. The report serves as a way to share new knowledge, insights, and discoveries with others in the field.
• Informing policy and practice : Research reports can inform policy and practice by providing evidence-based recommendations for decision-makers. For example, a research report on the effectiveness of a new drug could inform regulatory agencies in their decision-making process.
• Supporting further research: Research reports can provide a foundation for further research in a particular area. Other researchers may use the findings and methodology of a report to develop new research questions or to build on existing research.
• Evaluating programs and interventions : Research reports can be used to evaluate the effectiveness of programs and interventions in achieving their intended outcomes. For example, a research report on a new educational program could provide evidence of its impact on student performance.
• Demonstrating impact : Research reports can be used to demonstrate the impact of research funding or to evaluate the success of research projects. By presenting the findings and outcomes of a study, research reports can show the value of research to funders and stakeholders.
• Enhancing professional development : Research reports can be used to enhance professional development by providing a source of information and learning for researchers and practitioners in a particular field. For example, a research report on a new teaching methodology could provide insights and ideas for educators to incorporate into their own practice.

How to write Research Report

Here are some steps you can follow to write a research report:

• Identify the research question: The first step in writing a research report is to identify your research question. This will help you focus your research and organize your findings.
• Conduct research : Once you have identified your research question, you will need to conduct research to gather relevant data and information. This can involve conducting experiments, reviewing literature, or analyzing data.
• Organize your findings: Once you have gathered all of your data, you will need to organize your findings in a way that is clear and understandable. This can involve creating tables, graphs, or charts to illustrate your results.
• Write the report: Once you have organized your findings, you can begin writing the report. Start with an introduction that provides background information and explains the purpose of your research. Next, provide a detailed description of your research methods and findings. Finally, summarize your results and draw conclusions based on your findings.
• Proofread and edit: After you have written your report, be sure to proofread and edit it carefully. Check for grammar and spelling errors, and make sure that your report is well-organized and easy to read.
• Include a reference list: Be sure to include a list of references that you used in your research. This will give credit to your sources and allow readers to further explore the topic if they choose.
• Format your report: Finally, format your report according to the guidelines provided by your instructor or organization. This may include formatting requirements for headings, margins, fonts, and spacing.

Purpose of Research Report

The purpose of a research report is to communicate the results of a research study to a specific audience, such as peers in the same field, stakeholders, or the general public. The report provides a detailed description of the research methods, findings, and conclusions.

Some common purposes of a research report include:

• Sharing knowledge: A research report allows researchers to share their findings and knowledge with others in their field. This helps to advance the field and improve the understanding of a particular topic.
• Identifying trends: A research report can identify trends and patterns in data, which can help guide future research and inform decision-making.
• Addressing problems: A research report can provide insights into problems or issues and suggest solutions or recommendations for addressing them.
• Evaluating programs or interventions : A research report can evaluate the effectiveness of programs or interventions, which can inform decision-making about whether to continue, modify, or discontinue them.
• Meeting regulatory requirements: In some fields, research reports are required to meet regulatory requirements, such as in the case of drug trials or environmental impact studies.

When to Write Research Report

A research report should be written after completing the research study. This includes collecting data, analyzing the results, and drawing conclusions based on the findings. Once the research is complete, the report should be written in a timely manner while the information is still fresh in the researcher’s mind.

In academic settings, research reports are often required as part of coursework or as part of a thesis or dissertation. In this case, the report should be written according to the guidelines provided by the instructor or institution.

In other settings, such as in industry or government, research reports may be required to inform decision-making or to comply with regulatory requirements. In these cases, the report should be written as soon as possible after the research is completed in order to inform decision-making in a timely manner.

Overall, the timing of when to write a research report depends on the purpose of the research, the expectations of the audience, and any regulatory requirements that need to be met. However, it is important to complete the report in a timely manner while the information is still fresh in the researcher’s mind.

Characteristics of Research Report

There are several characteristics of a research report that distinguish it from other types of writing. These characteristics include:

• Objective: A research report should be written in an objective and unbiased manner. It should present the facts and findings of the research study without any personal opinions or biases.
• Systematic: A research report should be written in a systematic manner. It should follow a clear and logical structure, and the information should be presented in a way that is easy to understand and follow.
• Detailed: A research report should be detailed and comprehensive. It should provide a thorough description of the research methods, results, and conclusions.
• Accurate : A research report should be accurate and based on sound research methods. The findings and conclusions should be supported by data and evidence.
• Organized: A research report should be well-organized. It should include headings and subheadings to help the reader navigate the report and understand the main points.
• Clear and concise: A research report should be written in clear and concise language. The information should be presented in a way that is easy to understand, and unnecessary jargon should be avoided.
• Citations and references: A research report should include citations and references to support the findings and conclusions. This helps to give credit to other researchers and to provide readers with the opportunity to further explore the topic.

Advantages of Research Report

Research reports have several advantages, including:

• Communicating research findings: Research reports allow researchers to communicate their findings to a wider audience, including other researchers, stakeholders, and the general public. This helps to disseminate knowledge and advance the understanding of a particular topic.
• Providing evidence for decision-making : Research reports can provide evidence to inform decision-making, such as in the case of policy-making, program planning, or product development. The findings and conclusions can help guide decisions and improve outcomes.
• Supporting further research: Research reports can provide a foundation for further research on a particular topic. Other researchers can build on the findings and conclusions of the report, which can lead to further discoveries and advancements in the field.
• Demonstrating expertise: Research reports can demonstrate the expertise of the researchers and their ability to conduct rigorous and high-quality research. This can be important for securing funding, promotions, and other professional opportunities.
• Meeting regulatory requirements: In some fields, research reports are required to meet regulatory requirements, such as in the case of drug trials or environmental impact studies. Producing a high-quality research report can help ensure compliance with these requirements.

Limitations of Research Report

Despite their advantages, research reports also have some limitations, including:

• Time-consuming: Conducting research and writing a report can be a time-consuming process, particularly for large-scale studies. This can limit the frequency and speed of producing research reports.
• Expensive: Conducting research and producing a report can be expensive, particularly for studies that require specialized equipment, personnel, or data. This can limit the scope and feasibility of some research studies.
• Limited generalizability: Research studies often focus on a specific population or context, which can limit the generalizability of the findings to other populations or contexts.
• Potential bias : Researchers may have biases or conflicts of interest that can influence the findings and conclusions of the research study. Additionally, participants may also have biases or may not be representative of the larger population, which can limit the validity and reliability of the findings.
• Accessibility: Research reports may be written in technical or academic language, which can limit their accessibility to a wider audience. Additionally, some research may be behind paywalls or require specialized access, which can limit the ability of others to read and use the findings.

HOW TO WRITE CHAPTER TWO OF RESEARCH PROJECTS

A practical guide to research writing – chapter two.

Historically, Chapter Two of every academic Research/Project Write up has been Literature Review, and this position has not changed. When preparing your write up for this Chapter, you can title it “Review of Related Literature” or just “Literature Review”.

This is the chapter where you provide detailed explanation of previous researches that has been conducted on your topic of interest. The previous studies that must be selected for this chapter must be academic work/articles published in an internationally reputable journal.

Also, the selected articles must not be more than 10 years old (article publication date to project writing date). For better organization, it has been generally accepted that the arrangement for a good literature review write up follows this order:

2.0     Introduction

2.1     Conceptual Review

2.2     Theoretical Framework

2.3     Empirical review

Summary of Literature/Research Gap

2.0     INTRODUCTION

This serves as the preamble to the chapter alone or preliminary information on the chapter. All the preliminary information that should be provided here should cover just this chapter alone because the project already has a general introduction which is chapter one. It should only reflect the content of this chapter. This is why the introduction for literature review is sometimes optional.

Basically here, you should describe the contents of the chapter in few words

HIRE A PROFESSIONAL PROJECT WRITER

2.1     CONCEPTUAL REVIEW

This section can otherwise be titled “Conceptual Framework”. It must capture all explanations on the concepts that are associated with your research topic in logical order. For example, if your research topic is “A study of the effect of advertisement on firm sales”, your conceptual framework can best follow this order:

2.1     Conceptual Framework

2.1.1  Advertisement

2.1.1.1        Types of Advertisement

2.1.1.2.      Advantages of Advertisement

2.1.2  Concept of Firm Sales

2.1.2.1        Factor determining Firm Sales

These concepts must be defined and described from the historical point of view. Topical works and prevailing issues globally, in your continent and nation on the concepts should be presented here. You must be able to provide clear information here that there should be no ambiguity about the variables you are studying.

2.2     THEORETICAL FRAMEWORK

This can be otherwise titled “Theoretical Review”. This section should contain all previous professional theories and models that have provided explanations on your research topic in the recent past. Yes, related theories and models also falls within the category of past literature for your research write up. Professional theories that are most relevant to your topic should be separately arranged in this section, as seen in the example below:

2.2.1  Jawkwish Theory of Performance

2.2.2  Interstitial Theory of Ranking

2.2.3  Grusse Theory of Social Learning

But the most important thing to note while writing this part is that, apart from making sure that you must do a thorough research and ensure that the most relevant theories for your research topic is selected, your theoretical review must capture some important points which should better reflect in this order for each model:

The proponent of the theory/model, title and year of publication, aim/purpose/structure of the theory, contents and arguments of the theory, findings and conclusions of the theory, criticisms and gaps of the theory, and finally the relevance of the theory to your current research topic.

Best Research Writing eBook

Academic project or thesis or dissertation writing is not an easy academic endeavor. To reach your goal, you must invest time, effort, and a strong desire to succeed. Writing a thesis while also juggling other course work is challenging, but it doesn't have to be an unpleasant process. A dissertation or thesis is one of the most important requirements for any degree, and this book will show you how to create a good research write-up from a high level of abstraction, making your research writing journey much easier. It also includes examples of how and what the contents of each sub-headings should look like for easy research writing. This book will also constitute a step-by-step research writing guide to scholars in all research fields.

2.3     EMPIRICAL REVIEW

This can be otherwise titled “Empirical Framework”. This is usually described as the critical review of the existing academic works/literature on your research topic. This can be organized or arranged in two different alternative ways when developing your write up:

• It can be arranged in a table with heading arranged horizontally in this order: Author name and initials, year and title of publication, aim/objectives, methodology, findings, conclusions, recommendations, research gap. Responses for the above should be provided in spaces provided below in the table for up to 40 articles at least.
• The second option excludes the use of tables but still contains the same information exactly as above for tables. The information is provided in thematic text format with appropriate in-text references. Note that all these points to be included can be directly gotten from the articles except the research gap which requires your critical thinking. Your research gap must identify an important thing(s) the previous research has not done well or not done at all, which your current research intends to do. Although, you should criticize, but constructively while acknowledging areas of perfections and successes of the authors.

Note that every research you critically review must have evident/obvious gaps that your research intends to fill.

SUMMARY OF LITERATURE REVIEW/RESEARCH GAP/GAP ANALYSIS

This is the concluding part of every literature review write up. It provides the summary of the entire content of the whole Chapter. Sometimes, some institutions require that you bring the analysis of all the gaps of the existing literature under review here. Conclusions on the whole existing literature under review should briefly be highlighted in this section.

I trust that this article will help undergraduates and postgraduate researchers in writing a very good Literature Review for your Research/Project/Paper/Thesis, and will also meet the needs of our esteemed readers who has been requesting for a guide on how to write their Chapter Two (Literature Review).

Enjoy, as you develop a good Literature Review for your research!

Research Methods

Chapter 2 introduction.

Maybe you have already gained some experience in doing research, for example in your bachelor studies, or as part of your work.

The challenge in conducting academic research at masters level, is that it is multi-faceted.

The types of activities are:

• Finding and reviewing literature on your research topic;
• Designing a research project that will answer your research questions;
• Collecting relevant data from one or more sources;
• Analyzing the data, statistically or otherwise, and
• Writing up and presenting your findings.

Some researchers are strong on some parts but weak on others.

We do not require perfection. But we do require high quality.

Going through all stages of the research project, with the guidance of your supervisor, is a learning process.

The journey is hard at times, but in the end your thesis is considered an academic publication, and we want you to be proud of what you have achieved!

Probably the biggest challenge is, where to begin?

• What will be your topic?
• And once you have selected a topic, what are the questions that you want to answer, and how?

In the first chapter of the book, you will find several views on the nature and scope of business research.

Since a study in business administration derives its relevance from its application to real-life situations, an MBA typically falls in the grey area between applied research and basic research.

The focus of applied research is on finding solutions to problems, and on improving (y)our understanding of existing theories of management.

Applied research that makes use of existing theories, often leads to amendments or refinements of these theories. That is, the applied research feeds back to basic research.

In the early stages of your research, you will feel like you are running around in circles.

You start with an idea for a research topic. Then, after reading literature on the topic, you will revise or refine your idea. And start reading again with a clearer focus ...

A thesis research/project typically consists of two main stages.

The first stage is the research proposal .

Once the research proposal has been approved, you can start with the data collection, analysis and write-up (including conclusions and recommendations).

Stage 1, the research proposal consists of he first three chapters of the commonly used five-chapter structure :

• Chapter 1: Introduction
• An introduction to the topic.
• The research questions that you want to answer (and/or hypotheses that you want to test).
• A note on why the research is of academic and/or professional relevance.
• Chapter 2: Literature
• A review of relevant literature on the topic.
• Chapter 3: Methodology

The methodology is at the core of your research. Here, you define how you are going to do the research. What data will be collected, and how?

Your data should allow you to answer your research questions. In the research proposal, you will also provide answers to the questions when and how much . Is it feasible to conduct the research within the given time-frame (say, 3-6 months for a typical master thesis)? And do you have the resources to collect and analyze the data?

In stage 2 you collect and analyze the data, and write the conclusions.

• Chapter 4: Data Analysis and Findings
• Chapter 5: Summary, Conclusions and Recommendations

This video gives a nice overview of the elements of writing a thesis.

2 Chapter 2 (Introducing Research)

Joining a Conversation

Typically, when students are taught about citing sources, it is in the context of the need to avoid plagiarism. While that is a valuable and worthwhile goal in its own right, it shifts the focus past one of the original motives for source citation. The goal of referencing sources was originally to situate thoughts in a conversation and to provide support for ideas. If I learned about ethics from Kant, then I cite Kant so that people would know whose understanding shaped my thinking. More than that, if they liked what I had to say, they could read more from Kant to explore those ideas. Of course, if they disliked what I had to say, I could also refer them to Kant’s arguments and use them to back up my own thinking.

For example, you should not take my word for it that oranges contain Vitamin C. I could not cut up an orange and extract the Vitamin C, and I’m only vaguely aware of its chemical formula. However, you don’t have to. The FDA and the CDC both support this idea, and they can provide the documentation. For that matter, I can also find formal articles that provide more information. One of the purposes of a college education is to introduce students to the larger body of knowledge that exists. For example, a student studying marketing is in no small part trying to gain access to the information that others have learned—over time—about what makes for effective marketing techniques. Chemistry students are not required to derive the periodic table on their own once every four years.

In short, college classes (and college essays) are often about joining a broader conversation on a subject. Learning, in general, is about opening one’s mind to the idea that the person doing the learning is not the beginning nor the end of all knowledge.

Remember that most college-level assignments often exist so that a teacher can evaluate a student’s knowledge. This means that displaying more of that knowledge and explaining more of the reasoning that goes into a claim typically does more to fulfill the goals of an assignment. The difference between an essay and a multiple choice test is that an essay typically gives students more room to demonstrate a thought process in action. It is a way of having students “show their work,” and so essays that jump to the end without that work are setting themselves up for failure.

Learning, Not Listing

Aristotle once claimed “It is the mark of an educated mind to be able to entertain a thought without accepting it.” Many students are familiar with the idea of search . The internet makes it tremendously easy to search for information—and misinformation. It takes a few seconds to find millions of results on almost any topic. However, that is not research. Where, after all, is the re in all of that? The Cambridge Dictionary offers the following definition:

Research (verb): to study a subject in detail, especially in order to discover new information or reach a new understanding.

Nothing about that implies a casual effort to type a couple of words into search engine and assuming that a result on the first screen is probably good enough. Nor does that imply that a weighted or biased search question, like “why is animal testing bad” will get worthwhile results.  Instead, research requires that the researcher searches, learns a little, and then searches again . Additionally, the level of detail matters. Research often involves knowing enough to understand the deeper levels of the subject.

For example, if someone is researching the efficacy of animal testing, they might encounter a claim that mice share a certain percentage of their DNA with human beings. Even this is problematic, because measuring DNA by percentage isn’t as simple as it sounds. However, estimates range from 85% to 97.5%, with the latter number being the one that refers to the active or “working” DNA. Unfortunately, the casual reader still knows nothing of value about using mice for human research. Why? Because the casual reader doesn’t know if the testing being done involves the 97.5% or the 2.5%, or even if the test is one where it can be separated.

To put it bluntly, Abraham Lincoln once had a trip to the theater that started 97.5% the same as his other trips to the theater.

In order for casual readers to make sense of this single factoid, they need to know more about DNA and about the nature of the tests being performed on the animals. They probably need to understand biology at least a little. They certainly need to understand math at a high enough level to understand basic statistics. All of this, of course, assumes that the student has also decided that the source itself is worthy of trust. In other words, an activist website found through a search engine that proclaims “mice are almost identical to humans” or “mice lack 300 million base pairs that humans have”. Neither source is lying. Just neither source helps the reader understand what is being talked about (if the sources themselves even understand).

Before a student can write a decent paper, the student needs to have decent information. Finding that information requires research, not search. Often, student writers (and other rhetors) mistakenly begin with a presupposed position that they then try to force into the confines of their rhetoric.  Argumentation requires an investigation into an issue before any claim is proffered for discussion.  The ‘thesis statement’ comes last; in many ways it is the product of extensive investigation and learning. A student should be equally open to and skeptical of all sources.

Skepticism in Research

Skepticism is not doubting everyone who disagrees with you. True skepticism is doubting all claims equally and requiring every claim to be held to the same burden of proof (not just the claims we disagree with). By far, the biggest misconception novice writers struggle with is the idea that it is okay to use a low-quality source (like a blog, or a news article, or an activist organization) because they got “just facts” from that source.

The assumption seems to be that all presentations of fact are equally presented, or that sources don’t lie. However, even leaving aside that many times people do lie in their own interests, which facts are presented and how they are presented changes immensely. There’s no such thing as “just facts.” The presentation of facts matters, as does how they are gathered. Source evaluation is a fundamental aspect of advanced academic writing.

“Lies” of Omission and Inclusion:  One of the simplest ways to misrepresent information is simply to exclude material that could weaken the stance that is favored by the author. This tactic is frequently called stacking the deck , and it is obviously dishonest. However, there is a related problem known as observational bias , wherein the author might not have a single negative intention whatsoever. Instead, xe simply only pays attention to the evidence that supports xir cause, because it’s what’s relevant to xir.

• Arguments in favor of nuclear energy as a “clean” fuel source frequently leave out the problem of what to do with the spent fuel rods (i.e. radioactive waste). Similarly, arguments against nuclear energy frequently count only dramatic failures of older plants and not the safe operation of numerous modern plants; another version is to highlight the health risks of nuclear energy without providing the context of health risks caused by equivalent fuel sources (e.g. coal or natural gas).
• Those who rely on personal observation in support of the idea that Zoomers are lazy might count only the times they see younger people playing games or relaxing, ignoring the number of times they see people that same age working jobs or—more accurately—the times they don’t see people that age because they are too busy helping around the house or doing homework.

A source that simply lists ideas without providing evidence or justifying how the evidence supports its conclusions is likely not a source that meets the rigor needed for an academic argument. While later chapters will go into the subject in greater detail, these guidelines suggest that in general, news media are not ideal sources. Neither are activist webpages, nor are blogs or government outlets. As later chapters will explore, all of these “sources” are not in fact sources of information. Inevitably, these documents to not create information, they simply report it. Instead, finding the original studies (performed by experts, typically controlled for bias, and reviewed by other experts before being published) is a much better alternative.

Examining Sources Using the Toulmin Model

On most issues, contradictory evidence exists and the researcher must review the options in a way that establishes one piece of evidence as more verifiable, or as otherwise preferable, to the other.  In essence, researchers must be able to compare arguments to one another.

Stephen Toulmin introduced a model of analyzing arguments that broke arguments down into three essential components and three additional factors. His model provides a widely-used and accessible means of both studying and drafting arguments.

The Toulmin model can be complicated with three other components, as well: backing, rebuttals, and qualifiers. Backing represents support of the data (e.g. ‘the thermostat has always been reliable in the past’ or ‘these studies have been replicated dozens of times with many different populations’). Rebuttals, on the other hand, admit limits to the argument (e.g. ‘unless the thermostat is broken’ or ‘if you care about your long-term health’). Finally, qualifiers indicate how certain someone is about the argument (e.g. ‘it is definitely too cold in here’ is different than ‘it might be too cold in here’; likewise, ‘you might want to stop smoking’ is a lot less forceful than ‘you absolutely should stop smoking’).

At a minimum, an argument (either one made by the student or by a source being evaluated) should have all three of the primary components, even if they are incorporated together. However, most developed arguments (even short answers on tests or simple blog posts) should have all six elements in place. If they are missing, it is up to the reader to go looking for what is missing and to try to figure out why it might have been left out.

Here is an example of an underdeveloped argument that is simply phrased like an absolute claim of fact. It is a poor argument, in that it offers none of the rationale behind what it says—it just insists that it is correct:

“Other countries hate the United States for a reason.”

What other countries? What reason? Is it just one reason, or is it one reason per country?

By contrast, here is an argument that has at least some minimal development:

“In the eyes of many (Qualifier), the United States has earned the hatred of other countries (Claim). The U.S. involvement in Iranian politics alone has earned the country criticism (Data). By helping to overthrow a democratically elected leader in favor of a monarch in 1953, the U.S. acted in a manner that seemed hypocritical and self-interested (Backing). While many countries do act in favor of their own interests (Rebuttal), the U.S. publicly championing democracy while covertly acting against it serves to justify criticism of the country (Warrant).”

Is there room to disagree with this argument? Yes. However, this argument provides its rationale, it offers at least some sort of evidence for its claims, and it provides a place to begin engagement. A researcher who wishes to know more about this argument can go looking into the history of U.S.-Iran relations, for example.

When reviewing a source, or making their own arguments, researchers should consider the following questions. Is there evidence that can be verified and examined by others (in the same spirit as the scientific method)? More specifically:

• What is the claim?
• What data backs up this claim?
• What assumptions do I have to make to consider this evidence to be adequate support?

The various pieces of data which support claims in the Toulmin model are often called into question.  Studies are refuted, statistics countered with rival numbers, and their applicability to the claim in question is often murky.  Evidence—whether offered as matters of fact or as subjective considerations—does not exist in a vacuum.  Data are themselves claims.  If the supporting data are accepted as true, the argument has a generally accepted conclusion.  Such pieces of ‘evidence’ are contentions .

Although Toulmin distinguishes between qualifiers and rebuttal conditions, such a distinction is difficult to maintain in practice.  The important consideration—the one acknowledged by both terms—is that unconditional or absolute claims are difficult to support.  Specific fields have their own ways of hedging their bets.  Science has its error bar (Sagan) and the terminology of probability.  Statistics and polling have a margin of error.  Ethnography has its confrontation of personal bias.  When a rhetor expresses the limitations of a given claim, when the unconditional becomes conditional, claims become more than categorical propositions or thesis statements.  They become arguments.

Example 1:  Here is a minimalistic overview of one claim on the topic of traffic cameras.

• Claim = Traffic cameras increase minor accidents
• Evidence = David Kidwell and Alex Richards of The Chicago Tribune performed a study that was later cited by ABC News.
• Assumptions = This study was conducted honestly and reasonably represents the reality of accidents around these cameras (i.e. I can trust the agenda and the methods of the Chicago Tribune staff).

Example 2 : And here is a second claim on the same subject.

• Claim = The types of accidents by traffic cameras tend to be less severe
• Evidence = The Insurance Institute for Highway Safety examined national trends and compared medical reports, police reports, and various bills, posting the results on their website.
• Assumptions = If the IIHS has a bias, it would be toward fewer accidents, or at least less severe accidents (because this means they have to pay less money out).

As an Essay Fragment : According to some, traffic cameras actually increase accidents. A study conducted by the Chicago Tribune found that rear-end collisions increased when traffic cameras were installed, meaning that they make things worse, not better (Kidwell and Richards). However, the Insurance Institute for Highway Safety points out that while there are sometimes increases in minor collisions, the number of crashes resulting in injuries actually decreases.

• “According to…not better (Kidwell and Richards).” This uses a parenthetical source citation to provide a “link” to the evidence and to invite readers to examine both the data and the warrants.
• “However, the…decreases.” This uses a signal statement to introduce the source of the evidence first, often because the source has so much credibility the author is hoping to impress the reader.

Note that this is not a particularly powerful fragment–it is simply the  minimum level of rigor that a student should offer (or look for) in an academic essay or in an academic source.

Academic arguments typically make concessions.  These concessions help define the scope of the argument and the range of the inquiry.  In Section 1, I mentioned a relatively straightforward value claim: “Plan X is bad.”  Argumentation engages such value claims and defines their scope and limits.  Who is plan X bad for?  By what standards?  Why then is anyone in favor of plan X?  A more practical approach could be “If you favor Y, then Plan X is bad.”  This is a concession, of sorts—Plan X is only bad if you favor Y.  The argument admits that if you do not, then Plan X might not be all that bad, after all.

Such a concession, worded in such a way, has added merit.  It functions as what Aristotle would have called an artistic proof, although maybe not an enthymeme.  It establishes a bond between the rhetor and the audience through the shared favoring of Y; it nurtures consubtantiality—the basis of what Burke calls identification.  Clearly, concessions can be made in a way that both prevents some counterarguments from applying and still furthers a rhetorical point.

Such phrasing is practical, and only truly cynical interrogators would consider it sinister.  An inversion of this approach is possible.  “Unless you favor Y, Plan X is bad.”  So long as Y is sufficiently negative in the minds of the audience, the rhetor loses no actual impact here.  Here, connecting Y to X might require substantiation on the part of the rhetor, because the concession has become, itself, a justification of why X is bad (it is related to or involves Y).  The additional rhetorical power—gained through positive and negative associations—often compensates for such additional effort.

Chapter 2 Synopsis: The Organization of a Research Article

This chapter outlined the organizational structure of a research article, which is commonly referred to as IMRD/C. Each of those sections has specific goals and strategies that writers can use to optimize their ability to communicate research successfully. One way to envision the relationships between each of the IMRD/C sections is with the image of an hourglass.

The hourglass demonstrates the generality of the Introduction and the Discussion/Conclusion sections in contrast to the more specific nature of the middle two sections — Methods and Results. In the next four chapters, you’ll learn about each of those sections, respectively.

Key Takeaways

Each research article will contain distinct sections that tend to be rather consistent across disciplines, but could contain some individual variation within your discipline or even academic journal. The argument in an overall research article moves from being general to specific then back to more general again.

Writing a Research Paper Introduction | Step-by-Step Guide

Published on September 24, 2022 by Jack Caulfield . Revised on March 27, 2023.

The introduction to a research paper is where you set up your topic and approach for the reader. It has several key goals:

• Present your topic and get the reader interested
• Provide background or summarize existing research
• Position your own approach
• Detail your specific research problem and problem statement
• Give an overview of the paper’s structure

The introduction looks slightly different depending on whether your paper presents the results of original empirical research or constructs an argument by engaging with a variety of sources.

Step 1: introduce your topic, step 2: describe the background, step 3: establish your research problem, step 4: specify your objective(s), step 5: map out your paper, research paper introduction examples, frequently asked questions about the research paper introduction.

The first job of the introduction is to tell the reader what your topic is and why it’s interesting or important. This is generally accomplished with a strong opening hook.

The hook is a striking opening sentence that clearly conveys the relevance of your topic. Think of an interesting fact or statistic, a strong statement, a question, or a brief anecdote that will get the reader wondering about your topic.

For example, the following could be an effective hook for an argumentative paper about the environmental impact of cattle farming:

A more empirical paper investigating the relationship of Instagram use with body image issues in adolescent girls might use the following hook:

Don’t feel that your hook necessarily has to be deeply impressive or creative. Clarity and relevance are still more important than catchiness. The key thing is to guide the reader into your topic and situate your ideas.

This part of the introduction differs depending on what approach your paper is taking.

In a more argumentative paper, you’ll explore some general background here. In a more empirical paper, this is the place to review previous research and establish how yours fits in.

Argumentative paper: Background information

After you’ve caught your reader’s attention, specify a bit more, providing context and narrowing down your topic.

Provide only the most relevant background information. The introduction isn’t the place to get too in-depth; if more background is essential to your paper, it can appear in the body .

Empirical paper: Describing previous research

For a paper describing original research, you’ll instead provide an overview of the most relevant research that has already been conducted. This is a sort of miniature literature review —a sketch of the current state of research into your topic, boiled down to a few sentences.

This should be informed by genuine engagement with the literature. Your search can be less extensive than in a full literature review, but a clear sense of the relevant research is crucial to inform your own work.

Begin by establishing the kinds of research that have been done, and end with limitations or gaps in the research that you intend to respond to.

The next step is to clarify how your own research fits in and what problem it addresses.

Argumentative paper: Emphasize importance

In an argumentative research paper, you can simply state the problem you intend to discuss, and what is original or important about your argument.

Empirical paper: Relate to the literature

In an empirical research paper, try to lead into the problem on the basis of your discussion of the literature. Think in terms of these questions:

• What research gap is your work intended to fill?
• What limitations in previous work does it address?
• What contribution to knowledge does it make?

You can make the connection between your problem and the existing research using phrases like the following.

Now you’ll get into the specifics of what you intend to find out or express in your research paper.

The way you frame your research objectives varies. An argumentative paper presents a thesis statement, while an empirical paper generally poses a research question (sometimes with a hypothesis as to the answer).

Argumentative paper: Thesis statement

The thesis statement expresses the position that the rest of the paper will present evidence and arguments for. It can be presented in one or two sentences, and should state your position clearly and directly, without providing specific arguments for it at this point.

Empirical paper: Research question and hypothesis

The research question is the question you want to answer in an empirical research paper.

Present your research question clearly and directly, with a minimum of discussion at this point. The rest of the paper will be taken up with discussing and investigating this question; here you just need to express it.

A research question can be framed either directly or indirectly.

• This study set out to answer the following question: What effects does daily use of Instagram have on the prevalence of body image issues among adolescent girls?
• We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls.

If your research involved testing hypotheses , these should be stated along with your research question. They are usually presented in the past tense, since the hypothesis will already have been tested by the time you are writing up your paper.

For example, the following hypothesis might respond to the research question above:

The final part of the introduction is often dedicated to a brief overview of the rest of the paper.

In a paper structured using the standard scientific “introduction, methods, results, discussion” format, this isn’t always necessary. But if your paper is structured in a less predictable way, it’s important to describe the shape of it for the reader.

If included, the overview should be concise, direct, and written in the present tense.

Are cows responsible for climate change? A recent study (RIVM, 2019) shows that cattle farmers account for two thirds of agricultural nitrogen emissions in the Netherlands. These emissions result from nitrogen in manure, which can degrade into ammonia and enter the atmosphere. The study’s calculations show that agriculture is the main source of nitrogen pollution, accounting for 46% of the country’s total emissions. By comparison, road traffic and households are responsible for 6.1% each, the industrial sector for 1%. While efforts are being made to mitigate these emissions, policymakers are reluctant to reckon with the scale of the problem. The approach presented here is a radical one, but commensurate with the issue. This paper argues that the Dutch government must stimulate and subsidize livestock farmers, especially cattle farmers, to transition to sustainable vegetable farming. It first establishes the inadequacy of current mitigation measures, then discusses the various advantages of the results proposed, and finally addresses potential objections to the plan on economic grounds.

The rise of social media has been accompanied by a sharp increase in the prevalence of body image issues among women and girls. This correlation has received significant academic attention: Various empirical studies have been conducted into Facebook usage among adolescent girls (Tiggermann & Slater, 2013; Meier & Gray, 2014). These studies have consistently found that the visual and interactive aspects of the platform have the greatest influence on body image issues. Despite this, highly visual social media (HVSM) such as Instagram have yet to be robustly researched. This paper sets out to address this research gap. We investigated the effects of daily Instagram use on the prevalence of body image issues among adolescent girls. It was hypothesized that daily Instagram use would be associated with an increase in body image concerns and a decrease in self-esteem ratings.

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

11.2 Writing a Research Report in American Psychological Association (APA) Style

Learning objectives.

• Identify the major sections of an APA-style research report and the basic contents of each section.
• Plan and write an effective APA-style research report.

In this section, we look at how to write an APA-style empirical research report , an article that presents the results of one or more new studies. Recall that the standard sections of an empirical research report provide a kind of outline. Here we consider each of these sections in detail, including what information it contains, how that information is formatted and organized, and tips for writing each section. At the end of this section is a sample APA-style research report that illustrates many of these principles.

Sections of a Research Report

Title page and abstract.

An APA-style research report begins with a  title page . The title is centered in the upper half of the page, with each important word capitalized. The title should clearly and concisely (in about 12 words or fewer) communicate the primary variables and research questions. This sometimes requires a main title followed by a subtitle that elaborates on the main title, in which case the main title and subtitle are separated by a colon. Here are some titles from recent issues of professional journals published by the American Psychological Association.

• Sex Differences in Coping Styles and Implications for Depressed Mood
• Effects of Aging and Divided Attention on Memory for Items and Their Contexts
• Computer-Assisted Cognitive Behavioral Therapy for Child Anxiety: Results of a Randomized Clinical Trial
• Virtual Driving and Risk Taking: Do Racing Games Increase Risk-Taking Cognitions, Affect, and Behavior?

Below the title are the authors’ names and, on the next line, their institutional affiliation—the university or other institution where the authors worked when they conducted the research. As we have already seen, the authors are listed in an order that reflects their contribution to the research. When multiple authors have made equal contributions to the research, they often list their names alphabetically or in a randomly determined order.

It’s  Soooo  Cute!  How Informal Should an Article Title Be?

In some areas of psychology, the titles of many empirical research reports are informal in a way that is perhaps best described as “cute.” They usually take the form of a play on words or a well-known expression that relates to the topic under study. Here are some examples from recent issues of the Journal Psychological Science .

• “Smells Like Clean Spirit: Nonconscious Effects of Scent on Cognition and Behavior”
• “Time Crawls: The Temporal Resolution of Infants’ Visual Attention”
• “Scent of a Woman: Men’s Testosterone Responses to Olfactory Ovulation Cues”
• “Apocalypse Soon?: Dire Messages Reduce Belief in Global Warming by Contradicting Just-World Beliefs”
• “Serial vs. Parallel Processing: Sometimes They Look Like Tweedledum and Tweedledee but They Can (and Should) Be Distinguished”
• “How Do I Love Thee? Let Me Count the Words: The Social Effects of Expressive Writing”

Individual researchers differ quite a bit in their preference for such titles. Some use them regularly, while others never use them. What might be some of the pros and cons of using cute article titles?

For articles that are being submitted for publication, the title page also includes an author note that lists the authors’ full institutional affiliations, any acknowledgments the authors wish to make to agencies that funded the research or to colleagues who commented on it, and contact information for the authors. For student papers that are not being submitted for publication—including theses—author notes are generally not necessary.

The  abstract  is a summary of the study. It is the second page of the manuscript and is headed with the word  Abstract . The first line is not indented. The abstract presents the research question, a summary of the method, the basic results, and the most important conclusions. Because the abstract is usually limited to about 200 words, it can be a challenge to write a good one.

Introduction

The  introduction  begins on the third page of the manuscript. The heading at the top of this page is the full title of the manuscript, with each important word capitalized as on the title page. The introduction includes three distinct subsections, although these are typically not identified by separate headings. The opening introduces the research question and explains why it is interesting, the literature review discusses relevant previous research, and the closing restates the research question and comments on the method used to answer it.

The Opening

The  opening , which is usually a paragraph or two in length, introduces the research question and explains why it is interesting. To capture the reader’s attention, researcher Daryl Bem recommends starting with general observations about the topic under study, expressed in ordinary language (not technical jargon)—observations that are about people and their behavior (not about researchers or their research; Bem, 2003 [1] ). Concrete examples are often very useful here. According to Bem, this would be a poor way to begin a research report:

Festinger’s theory of cognitive dissonance received a great deal of attention during the latter part of the 20th century (p. 191)

The following would be much better:

The individual who holds two beliefs that are inconsistent with one another may feel uncomfortable. For example, the person who knows that he or she enjoys smoking but believes it to be unhealthy may experience discomfort arising from the inconsistency or disharmony between these two thoughts or cognitions. This feeling of discomfort was called cognitive dissonance by social psychologist Leon Festinger (1957), who suggested that individuals will be motivated to remove this dissonance in whatever way they can (p. 191).

After capturing the reader’s attention, the opening should go on to introduce the research question and explain why it is interesting. Will the answer fill a gap in the literature? Will it provide a test of an important theory? Does it have practical implications? Giving readers a clear sense of what the research is about and why they should care about it will motivate them to continue reading the literature review—and will help them make sense of it.

Breaking the Rules

Researcher Larry Jacoby reported several studies showing that a word that people see or hear repeatedly can seem more familiar even when they do not recall the repetitions—and that this tendency is especially pronounced among older adults. He opened his article with the following humorous anecdote:

A friend whose mother is suffering symptoms of Alzheimer’s disease (AD) tells the story of taking her mother to visit a nursing home, preliminary to her mother’s moving there. During an orientation meeting at the nursing home, the rules and regulations were explained, one of which regarded the dining room. The dining room was described as similar to a fine restaurant except that tipping was not required. The absence of tipping was a central theme in the orientation lecture, mentioned frequently to emphasize the quality of care along with the advantages of having paid in advance. At the end of the meeting, the friend’s mother was asked whether she had any questions. She replied that she only had one question: “Should I tip?” (Jacoby, 1999, p. 3)

Although both humor and personal anecdotes are generally discouraged in APA-style writing, this example is a highly effective way to start because it both engages the reader and provides an excellent real-world example of the topic under study.

The Literature Review

Immediately after the opening comes the  literature review , which describes relevant previous research on the topic and can be anywhere from several paragraphs to several pages in length. However, the literature review is not simply a list of past studies. Instead, it constitutes a kind of argument for why the research question is worth addressing. By the end of the literature review, readers should be convinced that the research question makes sense and that the present study is a logical next step in the ongoing research process.

Like any effective argument, the literature review must have some kind of structure. For example, it might begin by describing a phenomenon in a general way along with several studies that demonstrate it, then describing two or more competing theories of the phenomenon, and finally presenting a hypothesis to test one or more of the theories. Or it might describe one phenomenon, then describe another phenomenon that seems inconsistent with the first one, then propose a theory that resolves the inconsistency, and finally present a hypothesis to test that theory. In applied research, it might describe a phenomenon or theory, then describe how that phenomenon or theory applies to some important real-world situation, and finally suggest a way to test whether it does, in fact, apply to that situation.

Looking at the literature review in this way emphasizes a few things. First, it is extremely important to start with an outline of the main points that you want to make, organized in the order that you want to make them. The basic structure of your argument, then, should be apparent from the outline itself. Second, it is important to emphasize the structure of your argument in your writing. One way to do this is to begin the literature review by summarizing your argument even before you begin to make it. “In this article, I will describe two apparently contradictory phenomena, present a new theory that has the potential to resolve the apparent contradiction, and finally present a novel hypothesis to test the theory.” Another way is to open each paragraph with a sentence that summarizes the main point of the paragraph and links it to the preceding points. These opening sentences provide the “transitions” that many beginning researchers have difficulty with. Instead of beginning a paragraph by launching into a description of a previous study, such as “Williams (2004) found that…,” it is better to start by indicating something about why you are describing this particular study. Here are some simple examples:

Another example of this phenomenon comes from the work of Williams (2004).

Williams (2004) offers one explanation of this phenomenon.

An alternative perspective has been provided by Williams (2004).

We used a method based on the one used by Williams (2004).

Finally, remember that your goal is to construct an argument for why your research question is interesting and worth addressing—not necessarily why your favorite answer to it is correct. In other words, your literature review must be balanced. If you want to emphasize the generality of a phenomenon, then of course you should discuss various studies that have demonstrated it. However, if there are other studies that have failed to demonstrate it, you should discuss them too. Or if you are proposing a new theory, then of course you should discuss findings that are consistent with that theory. However, if there are other findings that are inconsistent with it, again, you should discuss them too. It is acceptable to argue that the  balance  of the research supports the existence of a phenomenon or is consistent with a theory (and that is usually the best that researchers in psychology can hope for), but it is not acceptable to  ignore contradictory evidence. Besides, a large part of what makes a research question interesting is uncertainty about its answer.

The Closing

The  closing  of the introduction—typically the final paragraph or two—usually includes two important elements. The first is a clear statement of the main research question and hypothesis. This statement tends to be more formal and precise than in the opening and is often expressed in terms of operational definitions of the key variables. The second is a brief overview of the method and some comment on its appropriateness. Here, for example, is how Darley and Latané (1968) [2] concluded the introduction to their classic article on the bystander effect:

These considerations lead to the hypothesis that the more bystanders to an emergency, the less likely, or the more slowly, any one bystander will intervene to provide aid. To test this proposition it would be necessary to create a situation in which a realistic “emergency” could plausibly occur. Each subject should also be blocked from communicating with others to prevent his getting information about their behavior during the emergency. Finally, the experimental situation should allow for the assessment of the speed and frequency of the subjects’ reaction to the emergency. The experiment reported below attempted to fulfill these conditions. (p. 378)

Thus the introduction leads smoothly into the next major section of the article—the method section.

The  method section  is where you describe how you conducted your study. An important principle for writing a method section is that it should be clear and detailed enough that other researchers could replicate the study by following your “recipe.” This means that it must describe all the important elements of the study—basic demographic characteristics of the participants, how they were recruited, whether they were randomly assigned to conditions, how the variables were manipulated or measured, how counterbalancing was accomplished, and so on. At the same time, it should avoid irrelevant details such as the fact that the study was conducted in Classroom 37B of the Industrial Technology Building or that the questionnaire was double-sided and completed using pencils.

The method section begins immediately after the introduction ends with the heading “Method” (not “Methods”) centered on the page. Immediately after this is the subheading “Participants,” left justified and in italics. The participants subsection indicates how many participants there were, the number of women and men, some indication of their age, other demographics that may be relevant to the study, and how they were recruited, including any incentives given for participation.

Figure 11.1 Three Ways of Organizing an APA-Style Method

After the participants section, the structure can vary a bit. Figure 11.1 shows three common approaches. In the first, the participants section is followed by a design and procedure subsection, which describes the rest of the method. This works well for methods that are relatively simple and can be described adequately in a few paragraphs. In the second approach, the participants section is followed by separate design and procedure subsections. This works well when both the design and the procedure are relatively complicated and each requires multiple paragraphs.

What is the difference between design and procedure? The design of a study is its overall structure. What were the independent and dependent variables? Was the independent variable manipulated, and if so, was it manipulated between or within subjects? How were the variables operationally defined? The procedure is how the study was carried out. It often works well to describe the procedure in terms of what the participants did rather than what the researchers did. For example, the participants gave their informed consent, read a set of instructions, completed a block of four practice trials, completed a block of 20 test trials, completed two questionnaires, and were debriefed and excused.

In the third basic way to organize a method section, the participants subsection is followed by a materials subsection before the design and procedure subsections. This works well when there are complicated materials to describe. This might mean multiple questionnaires, written vignettes that participants read and respond to, perceptual stimuli, and so on. The heading of this subsection can be modified to reflect its content. Instead of “Materials,” it can be “Questionnaires,” “Stimuli,” and so on. The materials subsection is also a good place to refer to the reliability and/or validity of the measures. This is where you would present test-retest correlations, Cronbach’s α, or other statistics to show that the measures are consistent across time and across items and that they accurately measure what they are intended to measure.

The  results section  is where you present the main results of the study, including the results of the statistical analyses. Although it does not include the raw data—individual participants’ responses or scores—researchers should save their raw data and make them available to other researchers who request them. Several journals now encourage the open sharing of raw data online.

Although there are no standard subsections, it is still important for the results section to be logically organized. Typically it begins with certain preliminary issues. One is whether any participants or responses were excluded from the analyses and why. The rationale for excluding data should be described clearly so that other researchers can decide whether it is appropriate. A second preliminary issue is how multiple responses were combined to produce the primary variables in the analyses. For example, if participants rated the attractiveness of 20 stimulus people, you might have to explain that you began by computing the mean attractiveness rating for each participant. Or if they recalled as many items as they could from study list of 20 words, did you count the number correctly recalled, compute the percentage correctly recalled, or perhaps compute the number correct minus the number incorrect? A final preliminary issue is whether the manipulation was successful. This is where you would report the results of any manipulation checks.

The results section should then tackle the primary research questions, one at a time. Again, there should be a clear organization. One approach would be to answer the most general questions and then proceed to answer more specific ones. Another would be to answer the main question first and then to answer secondary ones. Regardless, Bem (2003) [3] suggests the following basic structure for discussing each new result:

• Remind the reader of the research question.
• Give the answer to the research question in words.
• Present the relevant statistics.
• Qualify the answer if necessary.
• Summarize the result.

Notice that only Step 3 necessarily involves numbers. The rest of the steps involve presenting the research question and the answer to it in words. In fact, the basic results should be clear even to a reader who skips over the numbers.

The  discussion  is the last major section of the research report. Discussions usually consist of some combination of the following elements:

• Summary of the research
• Theoretical implications
• Practical implications
• Limitations
• Suggestions for future research

The discussion typically begins with a summary of the study that provides a clear answer to the research question. In a short report with a single study, this might require no more than a sentence. In a longer report with multiple studies, it might require a paragraph or even two. The summary is often followed by a discussion of the theoretical implications of the research. Do the results provide support for any existing theories? If not, how  can  they be explained? Although you do not have to provide a definitive explanation or detailed theory for your results, you at least need to outline one or more possible explanations. In applied research—and often in basic research—there is also some discussion of the practical implications of the research. How can the results be used, and by whom, to accomplish some real-world goal?

The theoretical and practical implications are often followed by a discussion of the study’s limitations. Perhaps there are problems with its internal or external validity. Perhaps the manipulation was not very effective or the measures not very reliable. Perhaps there is some evidence that participants did not fully understand their task or that they were suspicious of the intent of the researchers. Now is the time to discuss these issues and how they might have affected the results. But do not overdo it. All studies have limitations, and most readers will understand that a different sample or different measures might have produced different results. Unless there is good reason to think they  would have, however, there is no reason to mention these routine issues. Instead, pick two or three limitations that seem like they could have influenced the results, explain how they could have influenced the results, and suggest ways to deal with them.

Most discussions end with some suggestions for future research. If the study did not satisfactorily answer the original research question, what will it take to do so? What  new  research questions has the study raised? This part of the discussion, however, is not just a list of new questions. It is a discussion of two or three of the most important unresolved issues. This means identifying and clarifying each question, suggesting some alternative answers, and even suggesting ways they could be studied.

Finally, some researchers are quite good at ending their articles with a sweeping or thought-provoking conclusion. Darley and Latané (1968) [4] , for example, ended their article on the bystander effect by discussing the idea that whether people help others may depend more on the situation than on their personalities. Their final sentence is, “If people understand the situational forces that can make them hesitate to intervene, they may better overcome them” (p. 383). However, this kind of ending can be difficult to pull off. It can sound overreaching or just banal and end up detracting from the overall impact of the article. It is often better simply to end by returning to the problem or issue introduced in your opening paragraph and clearly stating how your research has addressed that issue or problem.

The references section begins on a new page with the heading “References” centered at the top of the page. All references cited in the text are then listed in the format presented earlier. They are listed alphabetically by the last name of the first author. If two sources have the same first author, they are listed alphabetically by the last name of the second author. If all the authors are the same, then they are listed chronologically by the year of publication. Everything in the reference list is double-spaced both within and between references.

Appendices, Tables, and Figures

Appendices, tables, and figures come after the references. An  appendix  is appropriate for supplemental material that would interrupt the flow of the research report if it were presented within any of the major sections. An appendix could be used to present lists of stimulus words, questionnaire items, detailed descriptions of special equipment or unusual statistical analyses, or references to the studies that are included in a meta-analysis. Each appendix begins on a new page. If there is only one, the heading is “Appendix,” centered at the top of the page. If there is more than one, the headings are “Appendix A,” “Appendix B,” and so on, and they appear in the order they were first mentioned in the text of the report.

After any appendices come tables and then figures. Tables and figures are both used to present results. Figures can also be used to display graphs, illustrate theories (e.g., in the form of a flowchart), display stimuli, outline procedures, and present many other kinds of information. Each table and figure appears on its own page. Tables are numbered in the order that they are first mentioned in the text (“Table 1,” “Table 2,” and so on). Figures are numbered the same way (“Figure 1,” “Figure 2,” and so on). A brief explanatory title, with the important words capitalized, appears above each table. Each figure is given a brief explanatory caption, where (aside from proper nouns or names) only the first word of each sentence is capitalized. More details on preparing APA-style tables and figures are presented later in the book.

Sample APA-Style Research Report

Figures 11.2, 11.3, 11.4, and 11.5 show some sample pages from an APA-style empirical research report originally written by undergraduate student Tomoe Suyama at California State University, Fresno.

Key Takeaways

• An APA-style empirical research report consists of several standard sections. The main ones are the abstract, introduction, method, results, discussion, and references.
• The introduction consists of an opening that presents the research question, a literature review that describes previous research on the topic, and a closing that restates the research question and comments on the method. The literature review constitutes an argument for why the current study is worth doing.
• The method section describes the method in enough detail that another researcher could replicate the study. At a minimum, it consists of a participants subsection and a design and procedure subsection.
• The results section describes the results in an organized fashion. Each primary result is presented in terms of statistical results but also explained in words.
• The discussion typically summarizes the study, discusses theoretical and practical implications and limitations of the study, and offers suggestions for further research.
• Practice: Look through an issue of a general interest professional journal (e.g.,  Psychological Science ). Read the opening of the first five articles and rate the effectiveness of each one from 1 ( very ineffective ) to 5 ( very effective ). Write a sentence or two explaining each rating.
• Practice: Find a recent article in a professional journal and identify where the opening, literature review, and closing of the introduction begin and end.
• Practice: Find a recent article in a professional journal and highlight in a different color each of the following elements in the discussion: summary, theoretical implications, practical implications, limitations, and suggestions for future research.

A research report is one big argument 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, distinct issues 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.

Performance Specifications for Rapid Highway Renewal (2014)

Chapter: chapter 2 - research methodology.

Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

12 C h a p t e r 2 Performance specifications emphasize desired outcomes and results, challenging owners and their industry partners to think in terms of user needs and to recognize that more than one solution may achieve the project objectives. Incorporating such concepts into a specification represents a distinct depar- ture from today’s build-to-print culture and demands a new approach to specification writing, contract administration, and construction execution. To help advance this new approach, the R07 research team developed guide specifications and associated implementation guidelines to support the application of performance speci- fications across a wide range of work and projects. In prepar- ing these documents, the team focused its research efforts on addressing the following fundamental questions: • What are performance specifications? • How are effective performance specifications developed and drafted? • Why use performance specifications? • What are the risks associated with using performance specifications? • When should performance specifications be used instead of method specifications? • Who is affected by the implementation of performance specifications and how are they affected? What are performance Specifications? Context drives how performance specifications are defined within the construction industry. For example, the U.S. Depart- ment of Defense (DoD) describes a performance specification as one that states requirements in terms of the required results and the criteria for verifying compliance, without specifically stating how the results are to be achieved. A performance specification describes the functional requirements for an item, its capa- bilities, the environment in which it must operate, and any interface, interoperability, or compatibility requirements. It does not present a preconceived solution to a requirement. (DoD 2009) In addition to addressing end-product performance, as contemplated by the DoD definition, requirements for a high- way construction project could conceivably extend to project- related performance in terms of work zone management, safety, and timely completion. Postconstruction and operational per- formance, as found in warranties and maintenance agreements, also could be included. The first task for the research team was therefore to con- duct a comprehensive literature review to establish what the term performance specifications encompasses when applied to the highway construction industry. Literature Review To provide focus to the literature review, the team first deter- mined which elements of a rapid renewal project would benefit from the development and implementation of performance specifications. Bearing in mind the objectives of rapid renewal (i.e., accelerated construction, minimal disruption, and long- life facilities), the team identified both physical products of con- struction (bridges, earthwork and geotechnical systems, and asphalt and concrete pavements) and project-level require- ments (work zone management, public relations, quality index- ing, and time incentives) as areas for possible application of performance specifications. To provide additional structure to the literature review, the team also established baseline definitions (presented in Appen- dix B) of specification types and contracting methods that would fall under the umbrella term performance specifications. As described in Chapter 1, performance specifications may be viewed in terms of a continuum. Categorizing specifications (e.g., as end-result specifications or PRS) helps identify the Research Methodology

13 advancement of performance specifications in a particular topic area. The literature review effort itself entailed collecting and reviewing reports, specifications, contract documents, and similar information to determine the status of performance specifying in each of the topic areas considered. The primary resources consulted included relevant FHWA, AASHTO, and NCHRP reports, as well as additional reports, contracts, and specifications from departments of transportation, industry, and international sources. Particular emphasis was placed on obtaining documents that addressed product performance measures, incentives, measurement and verification strategies, risk allocation techniques, legal and administrative issues, and other information relevant to the development and imple- mentation of performance specifications. Content Analysis The collected literature was classified according to specification type (e.g., end-result, PRS, warranty, and so on), topic area (e.g., pavement, bridge, work zone management, and so on), and project delivery approach (e.g., design-bid-build, design-build, design-build-operate-maintain). Then it was screened for per- ceived applicability to subsequent specification development efforts on the basis of containing or suggesting the following: • Progressive or creative performance parameters, measure- ment strategies, test methods (NDT or otherwise), or acceptance criteria appropriate to the rapid renewal environment; • Techniques to transfer performance responsibility from the owner to the contractor; • Actual or potential value of performance specifications; and • Conditions appropriate for the use of performance specifications. An annotated bibliography of documents is included in Appendix D. In addition, an index of existing performance specifications, collected as part of the literature review, is avail- able at the R07 report web page (http://www.trb.org/main/ blurbs/169107.aspx). how are effective performance Specifications Developed and Drafted? Historically, efforts at performance specifying (particularly in the pavement area) focused on the development and use of complex predictive models to establish specification require- ments. The research study undertaken for the R07 project adopted a more pragmatic approach that is amenable to, but not reliant on, the use of such models to define perfor- mance needs. The step-by-step process balances user needs and project goals against available technology and industry’s appetite for assuming performance risk, recognizing that such factors are often closely tied to the selected project delivery method. As illustrated by the suite of guide performance specifications prepared under this research study, the inherent flexibility of this approach makes it readily adaptable to different project elements and delivery methods. The complete performance specification development pro- cess is presented in the specification writers guide, Chapter 2. Agencies are encouraged to use the implementation guide- lines in conjunction with the guide specifications to tailor per formance requirements to project-specific conditions. Alter natively, agencies may develop additional performance specifications for needs not addressed by the current set of guide specifications. Specification Development Framework The primary function of a specification, whether prescriptive or performance oriented, is to communicate a project’s require- ments and the criteria by which the owner will verify confor- mance with the requirements. In this respect, performance specifications are similar to conventional method specifica- tions. Where they differ is the level at which performance must be defined. Figure 2.1—which was adapted from a model devel- oped by the Netherlands Ministry of Transport, Public Works, and Water Management—illustrates the possible requirement levels for a hypothetical pavement project (van der Zwan 2003). Taken as a whole, the pyramid depicted in the figure is intended to represent the entirety of knowledge and expe rience related to pavement design and construction. Taking and evaluating each level individually, the specifier can create a specification that is entirely prescriptive (if based solely on the material and workmanship properties defined on the lowest levels) or one that is more performance oriented (if based on the user needs and functional requirements described on the higher levels). For a particular project, the appropriate mix of perfor- mance requirements is driven by the project’s scope and objectives as well as the chosen project delivery approach and risk allo cation strategy. In practice, specifications typically include elements from several of the levels shown in Figure 2.1. Determining the appropriate balance between prescriptive and performance-oriented requirements is one of the main objectives of the eight-step specification development pro- cess illustrated Figure 2.2. Chapter 2 of the specification writ- ers guide describes this specification development framework in detail, systematically leading a specifier through each step in the process. However, as suggested by a review of the guide

14 specifications themselves, some steps are more critical to certain topic areas than to others. For example, although project deliv- ery approach (Step 3) plays a large role in shaping the develop- ment of a performance specification for pavements and bridges, it has less influence on establishing performance requirements for work zone management and geotechnical features. Application of the Performance Specification Framework To apply this framework to the main research areas of pave- ment, bridges, geotechnical systems, and work zone man- agement, the team first reviewed a cross section of existing performance specifications obtained through the literature review effort. Coordination with other SHRP and FHWA research projects provided additional information on topic areas that complemented the R07 effort to develop perfor- mance specifications for rapid renewal. The relevant projects addressed the following topics: • Advances in nondestructive testing techniques {e.g., SHRP 2 R06; FHWA Transportation Pooled Fund study [Project No. TPF-5(128)] on intelligent compaction}; • Innovative materials (e.g., SHRP 2 R19A); and • Mechanistic-based performance prediction (e.g., FHWA research study DTFH61-08-H-00005). The team carefully reviewed the collected literature, filter- ing existing performance specifications through the criteria established in the specification development framework to identify viable performance parameters and measurement strategies. Existing performance measures that met the frame- work criteria formed the basis for initial brainstorming ses- sions conducted among the team’s internal experts. Those existing measures, coupled with the team’s own project expe- rience, led to the development of draft performance require- ments which were then discussed and reviewed with external representatives from agencies and industry in formal work- shop settings. The input from external experts was used to refine and finalize the guide specifications and asso ciated commentary. Chapter 3 provides a more detailed summary of the findings from the literature review and outreach efforts in the context of the development of the guide specifications. To develop specifications that would be suitable for adop- tion by AASHTO, to the extent possible, the team adhered to the principles set forth in the National Highway Institute (NHI) Course No. 134001, Principles of Writing Highway Construction Specifications, and the FHWA Technical Advi- sory, Development and Review of Specifications (FHWA 2010). Even so, the team recognized that the typical AASHTO five- part format (Description, Materials, Construction, Measure- ment, Payment) may not be appropriate for every project delivery approach. For example, the lump-sum nature of a design-build contract may make measurement and payment sections unnecessary, whereas a warranty provision would require additional requirements related to bonding, distress evaluations, and required remedial action during the war- ranty period.

16 Why Use performance Specifications? Successful implementation of performance specifications will likely require a departure from traditional project development and delivery processes. To gain support for necessary changes, best practice suggests first establishing a compelling business case as to why performance specifica- tions represent a desired addition to an agency’s contracting toolbox. Literature Review To establish the rationale for using performance specifica- tions, the team first performed a literature review to docu- ment any prior efforts to identify the actual or potential value received through the use of performance-based, incentive- based, and performance warranty contracts and specifica- tions in the highway construction industry. Recognizing that performance specifications have not been widely applied to transportation projects in the United States, the team expanded its literature search to include research and practice from outside the highway industry. For example, the use of performance-based service contracts has become a standard business practice for some federal agencies, such as the Department of Defense (DoD), and the benefits of these contracts have been validated by research studies and best practice guides (OFPP 1998a; OFPP 1998b; DoD 2000). Although the benefits may not directly translate to the value added or lost by applying performance specifications to a highway construction project, they do provide general insight into the advantages of using performance contracting strategies. Value Assessment Research and practice, particularly from outside the highway industry, suggest that implementing performance specifica- tions has the potential to provide several advantages, includ- ing decreased life-cycle costs, reduced inspection, and improved quality and customer satisfaction. However, the literature contains little data quantifying the actual value added or lost by implementing performance specifications. Despite the lack of quantitative data, the literature does reflect the perception that using performance specifications or a performance contracting system will result in enhanced value (or performance) for highway agencies and road users. The literature also makes evident that these enhancements can be attributed, at least in part, to alternative project delivery systems that provide more flexibility and shift more responsibility to the private sector to achieve perfor- mance goals. Comparative Framework The team felt it was necessary to develop a comparative struc- ture to assess performance specifications against a benchmark. That comparison would allow consideration of how project delivery approaches could affect the actual or potential value received from implementing performance specifications. On the basis of the literature review and consultation with subject matter experts, the team generated a list of viable delivery schemes for performance specifications. The results of that effort led the team to use the following delivery meth- ods as the basis for assessing the perceived value of perfor- mance specifications: • Prescriptive (method) specifications (benchmark); • Design-bid-build, with some performance requirements, but no warranty (DBB+P); • Design-bid-build, with short-term warranty (DBB+STW); • Design-build, with no warranty (DB); • Design-build, with short-term warranty (DB+STW); and • Design-build-maintain (DBM). Recognizing that project conditions could also affect the value received from performance specifications, the compar- ative framework considered the impact of different project characteristics such as the following: • Road class (local, state highway, interstate, toll); • Type of construction (preservation, reconstruction, new construction); • Traffic [low, moderate, or high annual average daily traffic (AADT)]; • Location (urban, rural); • Complexity (depending on project phasing, right-of-way requirements, utilities, environmental issues, etc.); and • Climate (depending on moisture and temperature, by region). In the context of these delivery approaches and project char- acteristics, the team turned to expert participation in surveys and workshops to assess the perceived value of using perfor- mance specifications. Such nonexperimental research tech- niques were found to be applicable given the nature of the study. Factors such as delivery methods and project character- istics can be shown to affect the perceived value placed on the implementation of performance specifications on highway construction projects. However, the effect or extent of the rela- tionship cannot be determined with precision, as any one of the other factors can lead to the same or a similar effect. There- fore, the team relied on nonexperimental techniques, includ- ing surveys and documentation of experts’ comments elicited in a workshop setting, as means for data collection.

17 Delphi Analysis Although the survey method is a detailed and systematic method of data collection, response rates can be poor and the participating experts can leave out vital information. To bol- ster this technique, the team applied the Delphi method. The Delphi method is an adaptation of the survey method and is used to obtain the judgment of a panel of experts on a complex issue or topic. It is a systematic method of data col- lection and structured discussion that aims to minimize the effects of bias given the characteristic lack of anonymity in interviews and general surveys. The method is particularly useful in situations in which empirical means are not suitable and research results rely heavily on the subjective opinions of experts. In brief, a Delphi analysis entails an iterative process in which experts’ opinions are processed and used as feedback for further refinement of opinions generated in earlier sur- vey rounds. The iterative nature of the process is expected to yield more reliable results than a single survey round. The Delphi analysis required the team to (1) assemble the Delphi expert group; (2) develop and administer survey questions; (3) receive and process the survey responses; (4) conduct a structured workshop to present, discuss, and clarify the sur- vey results; (5) conduct a second survey round assessment; (6) summarize the outcomes of the Round 2 assessment, and (7) conduct a Round 3 assessment and summarize results. Appendix E provides a detailed summary of the design and results of this data collection effort. The Delphi survey results are provided in Appendix G. Demonstration Projects Perhaps the most powerful way to identify and communicate the potential benefits of performance specifications is through demonstration projects. The SHRP 2 R07 project therefore included an implementation phase designed to validate the guidelines and performance specifications developed during the research effort. The first step toward this end was to identify candidate agen- cies that would be willing to participate in a demonstration project. A survey questionnaire was developed to gauge the interest and experience of a representative sample of highway agencies in the United States, particularly those known to have experience or interest in performance specifications or alter- native project delivery methods. The survey included a brief description of the R07 project, including the project objectives and scope of the demonstration program. The survey document further explained that the team was seeking to work with two or more transportation agencies in implementing performance specifications on demonstra- tion projects to test and validate the use of performance specifications for rapid highway renewal projects. The R07 team offered to provide resources to work with agency per- sonnel to select an appropriate project or projects, develop the necessary performance specifications and contracting pro- visions, and assist with the administration of the project dur- ing design and construction, and, if applicable, during the maintenance and operation phase. Most important, the survey sought information as to (1) the likelihood that the agency would have projects suit- able for a demonstration of performance specifications in the 2010–2011 construction seasons and (2) the areas for which the agency would be most interested in performance specifying. Ten agencies returned questionnaires or sent e-mail responses indicating interest in participating in a SHRP 2 R07 demonstra- tion project. From those responses, the team identified the following projects as viable candidates for demonstrations: • Virginia DOT Route 208 Lake Anna Bridge Deck Rehabilita- tion Project—a shadow demonstration of the use of perfor- mance parameters that related more to long-term durability and performance; • Missouri DOT Route 141 Roadway Improvement Project— a demonstration of the use of nondestructive roller-integrated compaction monitoring (RICM), or intelligent compaction, to provide real-time and improved quality control of soil compaction operations; and • Louisiana DOTD U.S. Frontage Roads—a demonstration of the use of RICM and mechanistic-based in situ point measurements on a new pavement section. A more detailed discussion of these demonstrations is pro- vided in Chapter 3. What are the risks associated with Implementing performance Specifications? Risk in the context of performance specifications relates to the existence of any uncertain event or condition that, if it occurs, has a positive or negative effect on the objectives of the specification. The FHWA’s Guide to Risk Assessment and Allocation for Highway Construction Management presents a continuous, cyclical approach to risk assessment, involving the following steps: identify, assess and analyze, mitigate and plan, allocate, and monitor and update (Ashley et al. 2006). A similar approach was used to address the risks associated with performance specifications. As a key component of the specification development frame- work, the discussion of risk related to performance specifica- tions (i.e., identification and evaluation of risks) is addressed in the specification writers guide. The entire process of developing

18 a performance specification is in a sense a risk management exercise designed to identify, allocate, and mitigate the risks associated with implementing a performance specification. The generally accepted approach to project-level risk management—as described in FHWA’s Guide to Risk Assess- ment (Ashley et al. 2006) or the SHRP 2 R09 Guide for the Process of Managing Risk on Rapid Renewal Projects (Golder Associates et al. 2013)—is useful in developing a general frame- work for identifying risks; it is less useful in terms of analysis (e.g., quantifying the frequency and impacts of specification- related risks). In some cases the specification risks, such as gaps in performance measurement, are difficult to quantify given the current state of the practice (or level of understanding). For example, given the interest in the use of NDT and mechanistic properties for performance measurement, further research is needed to quantify the effects of risk related to variability or reliability of NDT versus traditional tests, or opportunities related to the use of mechanistic versus traditional perfor- mance measures. Additional long-term data collection will be needed to make valid quantitative risk assessments. The risk process described in the specification writers guide is geared to identifying risks and gaps and qualitatively deciding whether performance specifications are appropri- ate. Further, the guide assists in determining how to develop a performance specification to allocate risk among the proj- ect participants considering the current state of the practice. Further assessment of performance specification risks are needed to quantify the impacts or opportunities related to their use. When Should performance Specifications Be Used? Performance specifications are not ideal for every construc- tion contract or project circumstance. However, they may hold significant advantages over traditional method specifi- cations when certain criteria or conditions are met. To inte- grate performance specifications into an agency’s contracting toolbox, a process is needed to evaluate when to use or not to use performance specifications. The decision to use method or performance specifications is often a matter of degree (how much and at what level). Both approaches may be appropriate for specific elements within a project. In choosing the appropriate level of perfor- mance specifications, an organization’s culture, statutory restrictions, project objectives and characteristics, project delivery approach, and risk appetite all may play important parts in defining specifications. The interaction among these key factors will likely determine the preference for one type of specification over the other. The decision to use performance specifications versus method specifications can involve a relatively straightforward screening test, followed by a more in-depth analysis of the level and type of performance specifying appropriate for the project characteristics and contracting type. Thus, the imple- mentation guidelines (see the executive guide, Chapter 5) present a two-part decision process for evaluating when to use or not to use performance specifications. Part 1 of this decision process considers a project’s scope and goals. Part 2 addresses the project delivery considerations that could also affect the decision. Who Is affected by performance Specifications and how are they affected? For agency personnel, developing and implementing a scope of work in terms of user needs and end-result performance is often much more challenging and resource intensive than simply adhering to the agency’s standard specifications. For contractors, an initial investment may be needed to acquire the necessary knowledge, skills, and equipment to assume more responsibility for performance. While critical to a project’s success, a well-drafted perfor- mance specification will not in and of itself ensure that an agency’s performance goals will be met. Cultural, organiza- tional, and legal issues can also affect the successful imple- mentation of performance specifications. For this reason, the team prepared a set of implementation guidelines to accom- pany the guide specifications. In doing so, the team reviewed the existing literature, had discussions with practitioners from agencies and industry, and identified lessons learned from the demonstration projects. The goal was to address the following considerations: • The effect the decision to use performance specifications could have on an agency’s traditional project delivery phases, from project planning and preliminary engineering through to construction completion and possibly beyond to mainte- nance and asset management; • Any natural progression or transition from more traditional contracts and specifications that should precede the deci- sion to use performance specifications (i.e., a learning curve to attune both the agency and industry to a new business model); and the • General mechanics of administering performance con- tracts (e.g., procurement process, document and database management, and so on). This information, along with the key takeaways drawn from the other research tasks, was incorporated into both the imple- mentation guidelines and the guide specifications, as applica- ble, to provide agencies with the tools needed to develop and successfully implement performance specifications.

TRB’s second Strategic Highway Research Program (SHRP 2) Report S2-R07-RR-1: Performance Specifications for Rapid Highway Renewal describes suggested performance specifications for different application areas and delivery methods that users may tailor to address rapid highway renewal project-specific goals and conditions.

SHRP 2 Renewal Project R07 also produced:

• Implementation Guidelines: Volume I: Strategies for Implementing Performance Specifications: A Guide for Executives and Project Managers , which is designed to provide a broad overview of the benefits and challenges associated with implementing performance specifications.
• Implementation Guidelines: Volume II: Developing and Drafting Effective Performance Specifications: A Guide for Specification Writers , which presents a flexible framework that specifiers may use to assess whether performance specifying represents a viable option for a particular project or project element. If it is indeed a viable option, the guide discusses how performance specifications may then be developed and used to achieve project-specific goals and satisfy user needs.
• A pilot study , in partnership with the Missouri Department of Transportation, to investigate the effectiveness of selected quality assurance/quality control testing technologies.

A separate document, Guide Performance Specifications , includes model specifications and commentary to address implementation and performance targets (for acceptance) for 13 routine highway items. Agencies may adapt guide specifications to specific standards or project conditions. The commentary addresses gaps, risks, and options.
