Which term describes the extent to which a test measures what it claims to measure?

• A. Validity
• B. Reliability
• C. Accuracy
• D. Precision

Answer: (A)

Validity is the extent to which a test measures what it claims to measure. In PE, you want the test results to reflect the actual attribute being tested, such as aerobic endurance, rather than being skewed by factors like motivation, technique, or local muscular strength. If the test outcome depends on those extra factors, it may not truly indicate the intended fitness component, so the test isn’t valid. For example, a test should cover all aspects of the endurance domain (content validity), align with an established standard (criterion validity), and behave as theory predicts about the construct (construct validity). This focus on meaning and usefulness of the scores is what makes validity the correct concept here. Reliability deals with consistency, while accuracy and precision describe measurement error, but don’t by themselves ensure the test targets the right attribute.
