Commonly confused

Pairs that lose marks when they are blurred together.

  • Validity vs Reliability

    Validity: a study's truth to reality. Reliability: it means consistency on repetition.

  • Value relevance vs A value judgement

    Value relevance: values guiding a researcher's choice of topic. A value judgement: it means pronouncing on what ought to be.

  • Correlation vs Causation

    Correlation: variables moving together. Causation: one producing the other.

Questions from this topic

Each one with the model answer underneath.

  1. 1

    What does it mean to say that a piece of sociological research is valid?

    Model answer

    It means the research genuinely measures what it claims to measure, giving a true picture of the thing being studied.

  2. 2

    Distinguish between the validity and the reliability of a research method.

    Model answer

    Validity is whether the data are true to reality; reliability is whether the same method would produce the same data if repeated.

  3. 3

    Why do interpretivists argue that unstructured interviews produce more valid data than questionnaires?

    Model answer

    Because the respondent answers in their own words and can be probed, so the data reflect their real meanings rather than the categories the researcher imposed.

  4. 4

    What is the imposition problem in questionnaire design?

    Model answer

    The researcher's pre-set questions and answer options force respondents into categories that may not match how they actually think.

  5. 5

    Explain how the Hawthorne effect threatens validity.

    Model answer

    People who know they are being studied change their behaviour, so the researcher records the behaviour of subjects being observed rather than normal behaviour.

  6. 6

    Why is covert participant observation often defended on grounds of validity?

    Model answer

    Because the group does not know a researcher is present, so behaviour is unaffected by observation and the data record what people really do.
