A psychologist developed a training program for self-efficacy and he tested two independent groups of subjects for their change in self-efficacy with and without the training program and he has matched the IQ of the subjects for the control and the experimental groups and listed in the table accordingly. The results were shown below:

	Score for experimental group (with training)		Score for control group
Subject 1	11	Subject 11	10
Subject 3	18	Subject 20	12
Subject 4	19	Subject 7	16
Subject 6	15	Subject 17	14
Subject 9	14	Subject 10	13
Subject 12	16	Subject 2	15
Subject 13	14	Subject 14	13
Subject 16	12	Subject 15	12
Subject 18	15	Subject 8	14
Subject 19	19	Subject 5	20
