Define psychometrics.

• A. The study of air and the relationship between them
• B. The study of electricity in HVAC systems
• C. The measurement of noise in rooms
• D. The analysis of thermal bridges

Answer: (A)

Psychometrics is the science of measuring mental processes and attributes. It involves designing tests and scales to quantify things like knowledge, abilities, attitudes, and personality, turning qualitative judgments into numbers that can be analyzed. The aim is to produce measurements that are reliable (consistent across time and groups) and valid (actually assessing what you intend to measure). It also covers standardization, norms, and techniques for evaluating test items. The other topics listed refer to physical phenomena—air relationships, electricity, room noise, or thermal bridges—areas of engineering rather than how we quantify psychological attributes.
