Thus, there were seven groups altogether. The six groups were the independent variables in which they were manipulated while the seventh group serves as a control group. Half of the males in the six manipulated groups were provoked to be angry at the experimenter's "disguised" confederate while the others were not. In turn, they were also given the chance to shock the confederate. However, two-thirds of the subjects had weapons lying nearby the shock equipment before they administered the electric shocks. Of the two-thirds males, half were told the weapons belonged to the confederate while the others were told it belonged to a previous person in the room. The last third of the males had no weapons nearby. The seventh group (controlled group) consist of angered subjects with badminton racquets and shuttlecocks nearby the shock key. Before beginning the subjects were informed that the experiment was a study of physiological reactions to stress. Each individual's performance was to be evaluated in the form of electric shocks with intensity ranging from 1 to 10. 1 meaning good and 10 means very bad. The task is to come up with ideas of improving sales and then exchange them with the confederate in order to be evaluated. Soon afterward, the subject was told that he would be the first to receive the shocks. After receiving the electric shocks from the confederate, where it depended on what the experimenter's schedule of how many shocks to administer, the subject was then asked to fill out a questionnaire to rate his mood. Then, it was the subject's turn to administer the shocks. But beforehand, one group in the angered and non-angered states had no weapons nearby the shock keys while two other groups had a shotgun and a .38 caliber. Of the two groups, one was informed that the weapons belong to the confederate and the other to some previous person. The final angered group, instead, had badminton racquets and shuttlecocks.
