Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a structured interview?

    Model answer

    A structured interview uses a fixed set of pre-written questions asked in the same order to everyone. The interviewer does not add or change questions.

  2. 2

    Give one strength and one weakness of a structured interview.

    Model answer

    Structured interviews are easy to repeat and compare, so they are highly reliable. Answers cannot be followed up, so useful detail may be lost.

  3. 3

    What is a semi-structured interview?

    Model answer

    A semi-structured interview has some set questions, but the interviewer can add follow-up questions depending on the answers.

  4. 4

    Give one strength and one weakness of a semi-structured interview.

    Model answer

    Semi-structured interviews combine comparable core questions with the freedom to explore interesting answers. Interviews differ between people, making them harder to compare and replicate.

  5. 5

    What is an unstructured interview?

    Model answer

    An unstructured interview is like a conversation with no fixed questions. The interviewer follows the participant's answers from a general starting topic.

  6. 6

    Give one strength and one weakness of an unstructured interview.

    Model answer

    Unstructured interviews produce rich, detailed qualitative data from the participant's own point of view. Unstructured interviews are hard to replicate and analyse, and interviewer bias is more likely.
