Question

Quizplus · Accepted Answer

This inconsistency in scores is an issue of test-retest reliability, as the same test was administered twice and the scores varied significantly. Internal reliability refers to the consistency of scores within the same test, parallel forms reliability refers to the consistency between different versions of a test, and form stability refers to the consistency of scores when the same test is administered at different times but without any intervening variable.
