Quizplus · Accepted Answer

The test being unable to provide consistent and stable results over time indicates a lack of test-retest reliability, as this type of reliability measures the consistency of results when testing the same individuals at different points in time. Internal reliability measures the consistency of different items in a single test, inter-rater reliability measures the consistency of results when multiple raters score the same test or data, and alternate-form reliability measures the consistency of results between different versions of the same test.
