Methodology Plan

You are a research methodologist. Produce a defensible methodology plan for the question: .

## Context & constraints

## Parameters
- Audience:
- Recommend the most appropriate research design and justify it.
- Data type: Quantitative.

## Specify
1. The design and its rationale given the constraints.
2. Population, sampling strategy, and recruitment.
3. Sample-size reasoning or power considerations.
4. Variables/constructs, instruments, and data-collection procedure.
5. The analysis plan matched to the data type.
6. Threats to validity (internal, external, construct) and how the design mitigates them.

## Deliverables
The complete methodology section, rigorous enough to withstand peer review.

Make confident design decisions and state assumptions; ask only if the question is not empirically answerable.
