Show answer & explanation
Correct answer: D
Parallel/alternate-forms reliability: Two equivalent forms of a test should yield similar results.
Internal consistency: Items within the test are consistent with each other (often measured by Cronbach’s alpha).
Inter-rater reliability: Different scorers or observers provide consistent scores or judgments.
Note: Reliability is about consistency. Validity (genuineness) is about whether the test actually measures what it claims to measure. A test should be reliable to be useful, but reliability alone does not guarantee validity.
