The independent variables are manipulated by the experimenters.
A variable is something that can be changed like a property or value. Variables are commonly used in psychological experiments to determine whether changes in one thing lead to changes in another.
Variables play an important role in the research process of psychology. By effectively changing few variables in an experiment and measuring the results, researchers can gain knowledge about cause-and-effect relationships.
Independent variables are variables that are being manipulated by the experimenter. For example, in an experiment on the effects of sleep deprivation on test performance, sleep deprivation would be the independent variable. The experimenters caused some of the study participants to be sleep-deprived, while others were completely rested.
