In a dissertation, the methodology is perhaps the most important one. Whether it be a qualitative analysis or empirical study, the main focus of the thesis or dissertation is obviously the key findings and for that the methodology section assumes importance. You may lay the groundwork for your exercise with a detailed review of the literature and setting a suitable hypothesis in your study, but it is really what you have done that matters. writing a suitable methodology section is therefore very important and needs special attention.
Here are some tips on how to write a proper methodology section.
Method and methodology: First and foremost, you must understand the distinction between method and methodology. The methodology is about the underlying theory and analysis of the exercise you undertake; it is the set of principles behind the design of the research study. Methods on the other hand refer to the techniques and tools you use for the study. For instance, your methodology may include a sample survey, while your method is how you draw those samples. A proper methodology section needs to report both, in a proper structure so as not to confuse between both. Give an overview of the methodology you are following in your thesis and then report the methods adopted to execute it.
Qualify your methodology: At the very onset, you need to clarify the type of methodology you have adopted. Broadly, there are two types of a methodology based on two types of methods; empirical methods like primary surveys or experimentations best used for measuring or quantifying certain variables, and qualitative methods like interviews for contextualizing, or deriving deep insights on certain issues. You can also have mixed methods, combining both forms of inputs. All these methods come under the bigger umbrella of your thesis methodology, where you specify which methods you are using, and how.
Justify your methodology: You have to justify why the methodology you adopted is the best fit. This stems from the review of literature, the gaps you have identified in existing literature, the hypothesis you are exploring, and various other factors. While you contextualize your thesis to substantiate it, you also need to justify the methodology adopted for credibility. This involves a discussion of the strengths and weaknesses of your exercise, the reliability and limitations of your methods, what are the control mechanisms you have used for checking the validity of your results. You also need to clarify the observed results and how you interpret these results to derive qualitative conclusions.
Schematics and figures: It is very important to develop schematics of your methodology for ease of understanding. For instance, simple flowcharts help clarify matters to a great extent. You may also use complex infographics if it helps. Charts, flowcharts, diagrams are some tools you need to explore beforehand as they are often mandatory for certain types of methodology.
A well-developed methodology is an asset for your dissertation and helps raise it appreciation to a great extent.
