Answer 1

Answer:

C. Reliability of a test

.Test-retest reliability measures the consistency of test scores when the same test is administered to the same group of people on two different occasions.

• A high correlation between the two sets of scores indicates that the test produces stable and consistent results over time.

• This method is particularly useful for tests measuring stable traits or characteristics that are not expected to change significantly over short periods.

• It is one of the key ways to assess the reproducibility and stability of a test.
