Operational Definitions. To test an idea, one must gather data. This means one must relate ideas to concrete, measurable events in the world. That is why scientists need operational definitions, which are definitions that tell how to measure or detect something.
Operational Definitions. An operational definition is a detailed specification of how one would go about measuring a given variable. Operational definitions can range from very simple and straightforward to quite complex, depending on the nature of the variable and the needs of the researcher.perational definitions should be tied to the theoretical constructs under study. The theory behind the research often clarifies the nature of the variables involved and, therefore, would guide the development of operational definitions that would tap the critical variables.
