The 20 questions

  1. In psychological research, what does the term reliability measure?

    • Accuracy of findings
    • Truthfulness of measures
    • Generalisability of findings
    • Consistency of results

  2. How is test-retest reliability assessed for a psychological test?

    • Repeating the test
    • Correlating two halves
    • Comparing multiple observers
    • Consulting an expert

  3. Inter-observer reliability assesses the level of agreement between what?

    • Test items
    • Multiple observers
    • Experimental conditions
    • Participant scores

  4. What type of validity asks whether a measure superficially appears to measure its target construct?

    • Ecological validity
    • Predictive validity
    • Face validity
    • Concurrent validity

  5. How is concurrent validity demonstrated when evaluating a new psychological questionnaire?

    • Testing across time
    • Asking lay observers
    • Comparing established tests
    • Predicting future outcomes

  6. What type of validity concerns generalising findings to everyday real-world settings?

    • Ecological validity
    • Concurrent validity
    • Face validity
    • Temporal validity

  7. What type of validity concerns whether findings remain true over time?

    • Ecological validity
    • Population validity
    • Concurrent validity
    • Temporal validity

  8. A researcher gives an IQ test to the same participants two weeks apart and finds very similar scores. What does this show?

    • High test-retest reliability
    • High inter-observer reliability
    • Low ecological validity
    • High face validity

  9. Two observers agree on 90% of classroom behaviours. What does this indicate?

    • Inter-observer reliability
    • Test-retest reliability
    • Ecological validity
    • Concurrent validity

  10. A new anxiety scale correlates strongly with an established anxiety measure taken at the same time. What type of validity does this support?

    • Temporal validity
    • Concurrent validity
    • Face validity
    • Ecological validity

  11. A study of social attitudes conducted in the 1950s is used to make claims about attitudes today. Which problem is most relevant?

    • Inter-observer reliability
    • Temporal validity
    • Concurrent validity
    • Test-retest reliability

  12. A laboratory memory test uses artificial word lists that people rarely encounter in daily life. What validity problem does this raise?

    • Low ecological validity
    • Low test-retest reliability
    • Low inter-observer reliability
    • High temporal validity

  13. What is the best way to improve inter-observer reliability in an observational study?

    • Using double-blind controls
    • Increasing sample size
    • Operationalising behavioural categories
    • Conducting field experiments

  14. Which action best improves the validity of a questionnaire by assessing its items?

    • Calculating correlation coefficients
    • Conducting pilot studies
    • Using double-blind design
    • Increasing sample size

  15. A measure that consistently produces the exact same inaccurate result has high what?

    • Reliability only
    • Reliability and validity
    • Internal validity
    • Validity only

  16. What relationship exists between reliability and validity in psychological testing?

    • Reliability guarantees validity
    • Reliability is necessary
    • Validity is necessary
    • They are unrelated

  17. A test is consistent across repeated use but measures something other than the intended construct. Which problem is present?

    • High temporal validity
    • Low validity
    • Low reliability
    • High inter-observer reliability

  18. A test-retest correlation coefficient of +0.92 indicates high what?

    • Test-retest reliability
    • Inter-rater reliability
    • Concurrent validity
    • Ecological validity

  19. Which type of validity assesses whether a test superficially looks like it measures what it claims?

    • Temporal validity
    • Face validity
    • Predictive validity
    • Concurrent validity

  20. Why do unambiguous behavioural categories improve inter-observer reliability in observations?

    • Eliminates demand characteristics
    • Increases sample size
    • Ensures temporal validity
    • Reduces subjective interpretation
