What is the field that studies the measurement of human abilities, attitudes, and traits?

• A. Psychometrics
• B. Test norms
• C. Tests and scales
• D. Clinical method

Answer: (A)

Measuring human abilities, attitudes, and traits is psychometrics. This field covers the theory and methods for designing, analyzing, and interpreting psychological tests and scales, with a focus on making those measurements reliable and valid. It includes how tests are created, how to ensure their consistency across time and items, how to judge how well a test measures a specific construct, and how scores are standardized and interpreted using norms. Psychometrics underpins tools like intelligence tests, personality inventories, and attitude measures, as well as the process of developing new instruments. The other terms refer to parts of the measurement process or tools themselves (norms provide reference data for interpreting scores, tests and scales are the instruments used, and clinical method describes broader clinical practices rather than the measurement discipline).
