Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is a questionnaire and what are its main strengths and limitations?

    Model answer

    A questionnaire is a written instrument containing standardised questions that can be administered to large samples, producing quantifiable data but potentially lacking depth.

  2. 2

    What characterises structured interviews as a research method?

    Model answer

    Structured interviews use predetermined questions asked in a fixed order, producing standardised, comparable responses that can be quantified.

  3. 3

    How do semi-structured interviews combine different approaches?

    Model answer

    Semi-structured interviews combine elements of both structured and unstructured approaches, using some predetermined questions while allowing flexibility to explore responses in more depth.

  4. 4

    What distinguishes unstructured interviews from other interview formats?

    Model answer

    Unstructured interviews are open conversations without predetermined questions, allowing the discussion to flow naturally and explore topics in depth as they emerge.

  5. 5

    How does participant observation differ from non-participant observation?

    Model answer

    Participant observation involves the researcher joining the group being studied and taking part in their activities, while non-participant observation involves watching without direct involvement.

  6. 6

    What does manipulating an independent variable mean in sociological experiments?

    Model answer

    Manipulating an independent variable means deliberately changing or controlling one factor to observe what effect this has on another variable.
