Question: 1 / 400

Which of the following pairs correctly describes forms of reliability?

Test-retest and face validity

Equivalence and internal consistency

The correct pairing of forms of reliability is found in the choice that includes equivalence and internal consistency.

Equivalence refers to the reliability of two different forms of the same test. It measures the consistency of scores obtained by different versions of a test that have been designed to be equivalent. For instance, if two parallel forms of an exam yield similar results, this indicates a high degree of equivalence reliability.

Internal consistency, on the other hand, assesses the degree to which items within a single test or instrument are consistent in measuring the same construct. It is commonly evaluated using statistics such as Cronbach's alpha, which indicates how closely related a set of items are as a group.

Both equivalence and internal consistency are essential forms of reliability that ensure the validity and dependability of test scores, making this pairing correct in the context of the question.
