Like external validity, construct validity is related to generalizing. • Validity is concerned with the question: Are we measuring what we think we are measuring. Test-Retest Reliability. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same. Face validity Identify the following term that most closely refers to a judgement of the extent to which scores from a test can be used to infer, or predict, the examinees' performance in some activity: a.
