How does one discriminate between the dependent and independent variable in test questions. When you spend your days working at home, schools, or clinics, you’re probably not referring to behavior as the dependent variable and you’re probably not referring to procedures as independent variables. Which is why it is understandable that you may confuse these words, that are mostly used in research.

But for the exam, you have to pretend you’re researcher and you have to know these terms. Here’s how: the dependent variable is the behavior that we are targeting for change. So think of that behavior as being dependent on an intervention. Dependent behavior equals the behavior and the intervention. The independent variable– these are the consequences and environmental manipulations that can produce behavior change in a lab, but eventually end up in our hands and get called procedures and interventions. Also, the “i” in independent matches the “i” in intervention, which is another way to remember that.
