Independent Variable:An independent variable is exactly what it sounds like. It is a variable that stands alone and isn't changed by the other variables you are trying to measure. For example, someone's age might be an independent variable.
Dependent Variable:Just like an independent variable, a dependent variable is exactly what it sounds like. It is something that depends on other factors. ... (Independent variable) causes a change in (Dependent Variable) and it isn't possible that (Dependent Variable) could cause a change in (Independent Variable).
Control Variable:In a blind experiment, participants don't know whether they are in the experimental or control group. For example, in a study of a new experimental drug, participants in the control group may be given a pill (known as a placebo) that has no active ingredients but looks just like the experimental drug.
