Which is a strength of structured interviews?

• A. Takes longer to conduct.
• B. Eliminates bias completely.
• C. Increases differences.
• D. Reduces differences between interviewers.

Answer: (D)

Structured interviews standardize the data-collection process, with the same questions asked in the same order and a fixed way of prompting and recording answers. This consistency reduces how much interviewer style, tone, or clarifications can shape participants’ responses, so data collected by different interviewers are more comparable. In practice, that means higher reliability and easier comparison across interviewers and groups. While other statements can be true in some contexts, they aren’t the main advantage: the strength lies in reducing differences between interviewers, not in eliminating all bias, increasing differences, or necessarily taking longer as a universal rule.
