5. Suppose a test for independence of judgement was administered to three different groups of students. The higher the score, the more independent the person is in judgment (i.e., the person is not easily influenced b another person's opinions). Group A includes premedical students (n=11), Group B includes English majors (n=10) and Group C includes psychology majors (n=11). sample. A = sample. B sample.C = (69, 78,90, 92, 68,77,85, 96, 87,71,93) (44, 36, 41, 90, 51, 42,38,52,87,46) (36,97,84,72,75,64,62,79,63,66,58) (a) Is there a significant difference in judgement between Group A and B? Do both parametric and non-parametric tests, state 2 assumptions of the parametric and non- parametric test considered above. Comment on the difference in the conclusion if any between the two test. (b) Do state two the assumptions of the Kruskal Wallis test. (c) Carry out the Kruskal Wallis test to test for difference in judgement between the three groups 5.
