TASK 4
A clinical psychologist wishes to compare three methods for reducing hostility levels in university
students. A certain psychological test called hostility level test (HLT) was used to measure the
degree of hostility. High scores on this test were taken to indicate high hostility. A total of eleven
students were tested; five students were selected at random from among the eleven problem cases
and treated by method A. From the remaining 6, three were taken at random and treated by method 18
B. The other three students were treated by method C as indicated in following table:
