Test-retest reliability is a measure of consistency over time. In this example, Patrick's scores on the IQ test were consistent over a one-month period, indicating that the test has good test-retest reliability. Option B represents two different tests, which is not measuring test-retest reliability. Option C indicates variability in the test scores between different raters, which is not measuring test-retest reliability. Option D measures consistency within the test, but not over time.
