Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What is operationalisation?

    Model answer

    Turning an abstract concept into something that can actually be measured or observed.

  2. 2

    Suggest one way the concept of poverty could be operationalised.

    Model answer

    As a household income below a set proportion of the national median income.

  3. 3

    Explain why two studies of the same concept can reach different conclusions.

    Model answer

    They may have operationalised the concept differently, so they are counting different things under the same name.

  4. 4

    Why is the choice of research topic itself a practical matter as well as a theoretical one?

    Model answer

    A topic is only workable if the group can be reached, the funding exists and the work can be completed in the time available.

  5. 5

    How does the availability of funding shape what gets researched?

    Model answer

    Funders set priorities and timescales, so topics they favour attract research while others remain unstudied.

  6. 6

    Give one way limited time restricts a research design.

    Model answer

    It rules out longitudinal work and long ethnographies, pushing the researcher towards surveys and secondary data.
