What is operational definition example?

An operational definition is a statement that defines a variable or concept in terms of the specific procedures used to measure or manipulate it. It provides a clear description of how a particular construct will be observed, measured, or manipulated in a research study.

For example, if a researcher is interested in studying the concept of "aggression," they may provide an operational definition such as: "Aggression will be measured using the number of acts of physical violence observed in a controlled laboratory setting."

This operational definition clearly outlines how aggression will be observed and measured in the study, providing a specific and concrete way to assess the variable of interest. By using operational definitions, researchers can ensure that their findings are reliable, replicable, and meaningful.
