What measures how well a test correlates with the skill, trait, or behavior it is supposed to evaluate?

• A. Validity
• B. Reliability
• C. Predictive Validity
• D. Construct Validity

Answer: (A)

Validity is a crucial concept in educational psychology that refers to the degree to which a test accurately measures what it is intended to measure. When discussing how well a test correlates with the skill, trait, or behavior it aims to evaluate, validity provides the foundation for interpreting test scores meaningfully. For instance, if a test claims to measure mathematical ability, high validity would indicate that the scores truly reflect an individual's mathematical skills. Reliability, while also essential, focuses on the consistency of the test results over time and across different scenarios, rather than how well the test measures its intended construct. Predictive validity specifically refers to how well a test predicts future performance, usually in a specific context, while construct validity encompasses a broader examination of whether a test accurately reflects the theoretical trait or skill it is designed to measure. Therefore, the general concept of validity encompasses all these aspects, making it the most comprehensive choice regarding the measure of correlation with the intended evaluation.
