AP PSYCHOLOGY

Detailed explanation-1: -OPERATIONALISING YOUR VARIABLES Operationalising means stating your IV and DV in ways that make it obvious how they are being manipulated or measured. In particular, an operationalised DV will create quantitative data. For example: Not “intelligence” but “score on a IQ test"

Detailed explanation-2: -Variables in research can also be described by whether the experimenter thinks that they are the cause of a behavior (IV), or the effect (DV). The IV is the variable that you use to do the explaining and the DV is the variable being explained.

Detailed explanation-3: -Operationalising Independent Variables (IVs) and Dependent Variables (DVs): In experiments, the researcher manipulates the IV to find the effect it has on the DV. To preserve the internal validity of an experiment, the IV and DV must be operationalised.
