• What does face validity refer to?

  Face validity refers to the extent to which a test looks like it is measuring what it claims to measure.
• What does temporal validity refer to?

  Temporal validity refers to how behaviour can be generalised across time.
• What does concurrent validity refer to?

  Concurrent validity refers to how well the results from a study can be generalised to external situations/populations.
• What does reliability indicate about a test?

  Reliability indicates how consistent a test is.
• What does internal reliability refer to?

  Internal reliability refers to different parts of a test giving consistent results.
• What does external reliability refer to?

  External reliability refers to the test producing consistent results, regardless of when it is used.
• What is inter-rater reliability?

  Inter-rater reliability involves two researchers comparing results using the same resources and participants.
• What does test-re-test reliability involve?

  Test-re-test reliability involves doing the same test twice at different times.
• What is the split half method?

  The split half method splits the test into two halves, such as odd and even numbered questions, and checks for correlation.
• What is cultural validity?


  Behaviour that can be generalised to all cultures.
• What is external validity?


  External validity refers to the extent to which the findings of a study can be generalized to other populations, settings, or conditions.
