Refine Thesis Methodology

I’m polishing the methodology chapter of my master’s thesis and need a fresh, critical eye on the data-collection section. The study is built on a mixed-methods design: quantitative surveys paired with qualitative focus groups. I’m comfortable with the overall structure, but the justification, clarity, and academic rigour of the data-collection procedures still feel incomplete.

Here’s what I’m looking for:
• A thorough rewrite or annotated edit of the Data Collection subsection so that every step—from participant recruitment to instrument design—aligns logically with my research questions.
• Clear articulation of how the focus-group protocol complements the survey component, including triangulation rationale and any reliability/validity safeguards.
• Practical guidance on sample size, inclusion criteria, and ethical considerations, cited to current methodology literature (APA 7th).
• Polished, concise language that meets journal standards while retaining my scholarly voice.

If you’re experienced in mixed-methods research design and comfortable weaving qualitative focus groups into a broader quantitative framework, I’d love your help. A tracked-changes Word document plus a clean final version will complete the job.
