Detailed explanation-1: -Why is an operational definition necessary when reporting research findings? An operational definition allows others to replicate the procedure.
Detailed explanation-2: -Your operational definitions describe the variables you will use as indicators and the procedures you will use to observe or measure them. You need an operational definition because you can’t measure anything without one, no matter how good your conceptual definition might be.
Detailed explanation-3: -An operational definition allows the researchers to describe in a specific way what they mean when they use a certain term. Generally, operational definitions are concrete and measurable. Defining variables in this way allows other people to see if the research has validity.
Detailed explanation-4: -1c) Why are operational definitions necessary for making systematic investigations? The only way to ensure consistent data collection is by means of a detailed operational definition that eliminates ambiguity. It allows the data to be replicated and increases the accuracy.
Detailed explanation-5: -An operational definition specifies a measurement procedure (a set of operations) for measuring an external, observable behaviour, and uses the resulting measurements as a definition and measurement of the hypothetical construct.
