    Operational definition of a variable

    • A definition of a variable in terms of operations/activities that a research uses to measure/manipulate it

    • Gives a variable a concrete definition so you can actually use it in an experiment, this allows the researcher to maintain consistency.

    • All variables involved in a study should be operationalized

      • Dependent Variables (what is measured)

      • Independent Variables (what is manipulated)
