Quizplus · Accepted Answer

When manipulating an independent variable, at least two groups are created: a group that receives the manipulated independent variable (experimental group) and a group that does not receive the manipulated independent variable (control group). This comparison between the two groups allows researchers to determine the effect of the independent variable on the dependent variable.
