Explanation

Test-retest reliability assesses whether a test produces consistent results over time. By administering the same test twice with a one-month interval, the psychologist measures consistency. Low test-retest reliability would indicate the test is unstable or unreliable. This is different from validity, which measures whether the test measures what it claims to measure.
