1.2.1 - Questionnaire and interview design

1.2.1 Designing and conducting questionnaires and interviews, considering researcher effects.

Use - questionnaire and interview design to connect the rule to the data and decision in the question.

This matters because - questionnaire and interview design determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - questionnaire and interview design to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Questionnaire and interview design is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
