EXPERIMENTAL ANALYSIS

CASE 1

Samples of 10 students from two undergraduate math classes were purposively selected. Their heights being tall and small were used as basis for the assignment to experiment. The teacher assumed that the height of the student can be an indicator of student's intelligence. 5 students who are tall were assigned to Group 1 while the remaining 5 students who were small where assigned to Group 2. She then administered an IQ Test. Based on his records, 3 people from Group 1 had an IQ scores of 130, 1 was 110 and the other was 100. On the other group, 4 students had an IQ scores of 89 while 1 got 100.
