What is the term for the specific way a construct is measured?

• A. Operational Definition
• B. Measurement Procedure
• C. Instrument
• D. Scale

Answer: (A)

The main idea being tested is how a concept is turned into something you can observe and measure in a study. The term for the specific way a construct is measured is operational definition. It names exactly what counts as observing the construct and what counts as a measurement, using concrete actions, observations, or criteria. This makes the measurement clear and replicable. For example, if you’re studying stress, an operational definition might specify that stress is measured by the number of days in the past week with self-reported high stress on a standardized questionnaire or by a particular set of physiological indicators observed during a lab task. This differs from an instrument (the tool used to collect data), a scale (the system that assigns numbers to responses), or a measurement procedure (the steps you follow); the operational definition is about the precise way the construct is defined and observed.
