Reliability refers to the consistency and stability of a measure over time. To determine the reliability of an aptitude test, researchers assess the correlation between scores obtained on two separate completions of the same test. If the scores are highly correlated, it suggests that the test is reliable and produces consistent results. Therefore, the correct answer is D) reliability. Content validity refers to the extent to which a test measures the content it is intended to measure, predictive validity refers to the ability of a test to predict future performance or behavior, and normal distribution refers to the frequency distribution pattern of scores on a test. While these concepts are important in testing, they do not directly relate to the measurement of the consistency or stability of a test.
