Quizplus · Accepted Answer

The high correlation between the first and second scores indicates that the test is statistically reliable, or consistent in its measurement. This means that the test produces similar results over time and is therefore a reliable measure of whatever it is intended to assess. Validity refers to whether a test measures what it is intended to measure, so we cannot infer from the information given that the test has predictive validity or valid norms. Standardization refers to the process of administering a test in a consistent, standardized way, which may be relevant but is not directly implied by the information given about the correlation between scores.
