Quizplus · Accepted Answer

The goal of obtaining similar results time after time is related to the concept of reliability. Reliability refers to the consistency or stability of the scores obtained from a measure or test over time, across different raters or observers, or across similar items on a test. Therefore, the researcher's goal is to ensure that the musical aptitude test yields reliable scores, indicating that the measures assess the same underlying construct consistently. Validity refers to the extent to which a test measures what it claims to measure, generalizability refers to the extent to which the findings apply to other populations or settings, and standardization refers to the process of establishing norms or standards for interpreting test scores.
