Which type of reliability assesses the correlation between two different tests designed to evaluate the same constructs?

• A. Test-Retest Reliability
• B. Alternate Forms Reliability
• C. Split-Half Reliability
• D. Test Bias

Answer: (B)

The correct answer is that alternate forms reliability evaluates the correlation between two different tests designed to assess the same constructs. This type of reliability is important in educational and psychological testing because it helps to determine whether different versions of a test produce consistent results. By administering two different forms of a test that measure the same underlying construct, educators and researchers can assess the stability and consistency of the measurements. If the scores from both tests correlate highly, it indicates that the tests are reliable measures of the same concept despite using different items or wording. In contrast, test-retest reliability focuses on the consistency of scores over time when the same test is administered at different points. Split-half reliability evaluates the internal consistency of a single test by comparing scores from two halves of the test. Test bias, while significant in the context of fairness and equity in assessments, does not pertain specifically to the correlation between different tests.
