Question

Which one of the following methods of reliability examines the performance of a psychological test over time?

• A. Test-Retest Reliability
• B. Split-Half Reliability
• C. Inter-Scorer Reliability
• D. Alternate Form Reliability

Answer 1

The Correct Option is A

Test-retest reliability measures the consistency of test results over time by administering the same test to the same group on two separate occasions. A high correlation between the scores indicates reliability.

• Example: A well-designed IQ test should yield similar results for the same individual when taken weeks apart, assuming no significant external changes.
• Purpose: Ensures the stability and dependability of a test over time.
