How to Write Chapter 3 of the Dissertation
The main purpose of Chapter 3 of your dissertation, which is methodology, is to give enough information to an experienced investigator to be able to replicate the study. Some tutors ask students to create some kind of a textbook instead.
However, research should be structured appropriately to demonstrate all the major parts of the entire project, including measures and methods of the assignment that should work together in order to successfully address the main question of your study. Therefore, your third chapter should begin with the paragraph that shows the purpose of your study. Check and put some subjects to help you construct an effective methodology chapter.
The methodology chapter, which is usually Chapter 3, presents the information to let the reader understand all the steps and scientific methods used by researcher to learn more about validity and reliability of the study.
As any other chapter, this one should also start with a brief introduction. Here you should restate the purpose and add a small overview of a chapter. No need to apply much imagination, just write as follows: “Chapter 3 includes research methods design appropriateness review, a brief discussion of sample and population. In addition to that, Chapter 3 presents…”
Your introduction should be about three paragraphs and should not contain the title “Introduction”.
Some institutions make this section optional, the others require it to be included. Here you should specify if the research is experimental, quasi-experimental, causal-comparative, correlational, qualitative, quantitative, mixed methods, or another. Try to be as specific as possible. This kind of approach should be defended by comparing with other methods and denying those that do not meet the needs of your study.
This section should not be structured as a simple textbook-like description of different research designs, but rather focused on the effort to find the most rational design appropriate to your study.
Base this section on the problem you investigate, the theoretical framework of a study, and its purpose. Include sufficient details to suggest some recommendations about the answers to the core research questions. The main aim of this section is to convince the reader that the chosen approach and research design is maximum appropriate for the desired results.
This section should explicate the type of research design you use (historical, correlational, phenomenological, etc.). Also, one should justify and demonstrate deviations from the steps necessary to complete the research design.
Include a description of the independent variables and dependent variables. The dependent one is a response that is influenced by the independent treatment. The independent variables are under the researcher’s control, and they provide act as a factor of a study. Thus, if you are performing a qualitative study, there are no independent and dependent variables.
The research design should establish a strong sequence of the events in a research process. The size of this section depends on the number of experiments performed and results expected.
So, the detailed explanation of each method and point should be documented. Include the following elements:
- • Highlight a rationale for your research method (qualitative, quantitative, or mixed) and appropriateness. Don’t forget to include an explanation why you have selected a certain method instead of another.
- • Highlight a rationale that would explain why the chosen research design (experimental or non-experimental, for instance) is suitable for the study. Here you should not provide a list and descriptions of different types of design, but rather explain why the chosen one fits the best.
- • Show how the design you have chosen will help to accomplish the goals of a study.
- • Describe the reasons why the chosen design is the most appropriate choice for this research.
Summarize all you have written in the last part of this section. The last paragraph should include a short explanation of data analysis. Conclude it with a sentence that would introduce the next chapter of your dissertation.

I. Groups of Research Methods
There are two main groups of research methods in the social sciences:
- The empirical-analytical groupapproaches the study of social sciences in a similar manner that researchers study the natural sciences. This type of research focuses on objective knowledge, research questions that can be answered yes or no, and operational definitions of variables to be measured. The empirical-analytical group employs deductive reasoning that uses existing theory as a foundation for formulating hypotheses that need to be tested. This approach is focused on explanation.
- The interpretative group of methods is focused on understanding phenomenon in a comprehensive, holistic way. Interpretive methods focus on analytically disclosing the meaning-making practices of human subjects [the why, how, or by what means people do what they do], while showing how those practices arrange so that it can be used to generate observable outcomes. Interpretive methods allow you to recognize your connection to the phenomena under investigation. However, the interpretative group requires careful examination of variables because it focuses more on subjective knowledge.
The introduction to your methodology section should begin by restating the research problem and underlying assumptions underpinning your study. This is followed by situating the methods you will use to gather, analyze, and process information within the overall “tradition” of your field of study and within the particular research design you have chosen to study the problem. If the method you choose lies outside of the tradition of your field [i.e., your review of the literature demonstrates that it is not commonly used], provide a justification for how your choice of methods specifically addresses the research problem in ways that have not been utilized in prior studies.
The remainder of your methodology section should describe the following:
- Decisions made in selecting the data you have analyzed or, in the case of qualitative research, the subjects and research setting you have examined,
- Tools and methods used to identify and collect information, and how you identified relevant variables,
- The ways in which you processed the data and the procedures you used to analyze that data, and
- The specific research tools or strategies that you utilized to study the underlying hypothesis and research questions.
In addition, an effectively written methodology section should:
- Introduce the overall methodological approach for investigating your research problem. Is your study qualitative or quantitative or a combination of both (mixed method)? Are you going to take a special approach, such as action research, or a more neutral stance?
- Indicate how the approach fits the overall research design. Your methods for gathering data should have a clear connection to your research problem. In other words, make sure that your methods will actually address the problem. One of the most common deficiencies found in research papers is that the proposed methodology is not suitable to achieving the stated objective of your paper.
- Describe the specific methods of data collection you are going to use, such as, surveys, interviews, questionnaires, observation, archival research. If you are analyzing existing data, such as a data set or archival documents, describe how it was originally created or gathered and by whom. Also be sure to explain how older data is still relevant to investigating the current research problem.
- Explain how you intend to analyze your results. Will you use statistical analysis? Will you use specific theoretical perspectives to help you analyze a text or explain observed behaviors? Describe how you plan to obtain an accurate assessment of relationships, patterns, trends, distributions, and possible contradictions found in the data.
- Provide background and a rationale for methodologies that are unfamiliar for your readers. Very often in the social sciences, research problems and the methods for investigating them require more explanation/rationale than widely accepted rules governing the natural and physical sciences. Be clear and concise in your explanation.
- Provide a justification for subject selection and sampling procedure. For instance, if you propose to conduct interviews, how do you intend to select the sample population? If you are analyzing texts, which texts have you chosen, and why? If you are using statistics, why is this set of data being used? If other data sources exist, explain why the data you chose is most appropriate to addressing the research problem.
- Describe potential limitations. Are there any practical limitations that could affect your data collection? How will you attempt to control for potential confounding variables and errors? If your methodology may lead to problems you can anticipate, state this openly and show why pursuing this methodology outweighs the risk of these problems cropping up.
NOTE: Once you have written all of the elements of the methods section, subsequent revisions should focus on how to present those elements as clearly and as logically as possibly. The description of how you prepared to study the research problem, how you gathered the data, and the protocol for analyzing the data should be organized chronologically. For clarity, when a large amount of detail must be presented, information should be presented in sub-sections according to topic.
ANOTHER NOTE: If you are conducting a qualitative analysis of a research problem, the methodology section generally requires a more elaborate description of the methods used as well as an explanation of the processes applied to gathering and analyzing of data than is generally required for studies using quantitative methods. Because you are the primary instrument for generating the data, the process for collecting that data has a significantly greater impact on producing the findings. Therefore, qualitative research requires a more detailed description of the methods used.
III. Problems to Avoid
The methodology section of your paper should be thorough but to the point. Do not provide any background information that doesn’t directly help the reader to understand why a particular method was chosen, how the data was gathered or obtained, and how it was analyzed.
Unnecessary Explanation of Basic Procedures
Remember that you are not writing a how-to guide about a particular method. You should make the assumption that readers possess a basic understanding of how to investigate the research problem on their own and, therefore, you do not have to go into great detail about specific methodological procedures. The focus should be on how you applied a method, not on the mechanics of doing a method. An exception to this rule is if you select an unconventional methodological approach; if this is the case, be sure to explain why this approach was chosen and how it enhances the overall process of discovery.
It is almost a given that you will encounter problems when collecting or generating your data, or, gaps will exist in existing data or archival materials. Do not ignore these problems or pretend they did not occur. Often, documenting how you overcame obstacles can form an interesting part of the methodology. It demonstrates to the reader that you can provide a cogent rationale for the decisions you made to minimize the impact of any problems that arose.
Just as the literature review section of your paper provides an overview of sources you have examined while researching a particular topic, the methodology section should cite any sources that informed your choice and application of a particular method [i.e., the choice of a survey should include any citations to the works you used to help construct the survey].
It’s More than Sources of Information!
A description of a research study's method should not be confused with a description of the sources of information. Such a list of sources is useful in and of itself, especially if it is accompanied by an explanation about the selection and use of the sources. The description of the project's methodology complements a list of sources in that it sets forth the organization and interpretation of information emanating from those sources.
