A psychologist conducts an experiment to assess the effects of wearing high heeled shoes in increasing student's self-esteem. He selects his subjects who have records of low self-esteem at the guidance office and assigned them to two treatment conditions. Fifteen (15) students assigned to groups: 5 of them were instructed to wear 2 inches high heeled shoes while the other 5 were instructed to wear 1 inch high heeled shoes. The remaining 5 were allowed to use flat shoes. Their self-esteem were measured before and after the test. The difference in their Group 1 self-esteem were as follows: 5,4,6,8,5 while Group 2 were the following 1,2,2,1,0 and Group 3 had the following differences: 1,2,2,1,0
