The independent variable is the variable that is being manipulated or changed by the researcher in order to observe its effect on the dependent variable, which is the behavior being studied. Therefore, the independent variable is the variable that causes changes in the behavior being studied. Control variables are held constant in order to ensure that any observed changes are due to the independent variable and not due to other extraneous variables. Random variables are variables that are not controlled or manipulated by the researcher, and thus, they do not cause changes in the behavior being studied.
