The foot-in-the-door phenomenon can be tested by a researcher by randomly dividing sixty people into two groups.
Foot-in-the-door is an activity used by the researcher to minimize the aggressiveness of the driver.
In the foot-in-the-door technique, the researcher requests the first group to put the 'drive carefully' board on the windows as well as to put the same sign in the form of a larger board in their backyards of the house. The researcher requests the second group to put the larger signboards only in their yards and not on the windows of their houses.
Therefore, the researcher randomly assigns sixty individuals to two groups for testing the foot-in-the-door technique.
