The control group is the group that serves as a comparison and receives the standard or normal condition. In this experiment, the control group would be the group of students who took the exam in the regularly lit room because they received the standard or normal condition, while the group of students who took the exam in the dimly lit room received the manipulated variable of dim lighting.
