What is a key difference between structured and unstructured interviews?

• A. Structured interviews are flexible, while unstructured ones are not
• B. Structured interviews use predetermined questions, unstructured ones do not
• C. Unstructured interviews are usually shorter than structured interviews
• D. Structured interviews focus on qualitative data, unstructured on quantitative data

Answer: (B)

The key difference between structured and unstructured interviews lies in the nature of the questions asked. Structured interviews employ a set of predetermined questions, which ensures consistency across all interviews conducted. This format allows for easier comparison of responses and analysis, particularly when quantifying data. Each participant is asked the same questions in the same order, which helps to minimize variability in responses due to the interview process itself.

In contrast, unstructured interviews are more conversational and do not rely on a fixed set of questions. They allow respondents to express their thoughts and feelings more freely, making the interview process more flexible. This can lead to richer, more nuanced qualitative data as interviewers can explore topics more deeply based on the participant’s responses.

The other options discuss aspects that are either misleading or inaccurate regarding the characteristics and purposes of structured and unstructured interviews.
