Explanation
★An operational definition defines a concept in terms of specific and empirical measures, so that is the answer.
★An operational definition tells exactly how a concept will be measured in the study.
★So it defines the concept through specific, observable and measurable operations.
★It is not unrelated to the underlying concept; it is the very way that concept is measured.
★It is not an abstract, theoretical definition, which describes the concept in general terms.
★It is not based on personal opinion, so an operational definition is stated in specific, empirical measures.
