Methodology chapters fail in a predictable way: they explain what positivism is, what a questionnaire is and what SPSS does, without ever explaining why those were right for this study. Textbook definitions earn nothing on their own. Every paragraph should end by connecting a concept to a decision you made.
Many courses expect this structure explicitly, often referencing the research onion. Even where they do not, moving from philosophy down to technique produces a chapter that reads as reasoned rather than assembled.
The strongest justification names the alternative and rejects it: "A cross-sectional survey was selected over a longitudinal design because the research questions concern current perceptions rather than change over time, and because the study period did not permit repeated measurement." One sentence like that is worth a page of definitions. Do this for the design, the sampling technique, the instrument and the analysis method.
State the target population, the sampling frame, the technique, the achieved sample size and the response rate. If you used convenience sampling because that was what access permitted, say so and discuss the effect on generalisability. Examiners are far more comfortable with an acknowledged limitation than with a convenience sample described as though it were random.
Say exactly how the data was analysed: which software, which tests for which hypotheses, which significance level; or for qualitative work, which analytic approach, how coding proceeded and how themes were generated. For ethics, cover approval, informed consent, the right to withdraw, anonymity and data handling under your institution's policy — and attach consent forms and approval evidence in an appendix.
Why this design and not another? How do you know your instrument measures what you claim? What are the limitations of your sample? What would you do differently? If your chapter already answers these in writing, the viva becomes a conversation rather than an interrogation.
Assignment Byte can review your methodology chapter for justification quality, alignment with your research questions and viva readiness.
