Answer:
An operational definition is the preise meaning of a term used to describe a variable such as a type of behavior, which researchers want to measure.
Explanation:
Every variable used in a research must have two definitions: the conceptual definition and the operational definition. The conceptual definition is the one that can be found in a dictionary, it explains the construct and its relationship to other constructs. The operational definition defines de variable in terms of observable constructs that can be measured empirically. For example, when studying different types of behavior, the operational definition must make clear what empirical elements define each type of behavior.
