A strong methodology chapter answers three questions in order: what was done, why it was the right choice, and how it was executed with enough detail to be reproducible.
Reviewers look for explicit justification of design choices, a clear description of the sample and instruments, and an honest account of limitations. Vague language in this chapter is one of the most common reasons for revision requests.
Working through each subsection with a research-support partner before submission can surface gaps early, while there is still time to address them.
