Which concept is defined as an internal attribute that cannot be directly observed?

• A. Construct
• B. Variable
• C. Trait
• D. Phenomenon

Answer: (A)

A construct is an abstract internal attribute that cannot be directly observed. In research, such attributes are inferred from multiple observable indicators—survey items, test scores, or observed behaviors—and researchers build an operational definition to estimate the construct. Examples include intelligence, motivation, or anxiety; you can’t measure them with a single direct observation, but you can assess them through a coordinated set of measures. A variable is any characteristic that can take on different values and can be measured or observed directly in some form, not necessarily requiring inference. A trait is a relatively stable characteristic that can be inferred from behavior but isn’t defined strictly as something unobservable. A phenomenon refers to an event or process that can be observed or experienced; it isn’t about an internal attribute that requires operationalization.
