Question

Transcribed Image Text:The data in Table 15.9 were collected using a completely randomized design. They
are the achievement test scores for four different groups of students, each group taught
by a different teaching technique. The objective of the experiment is to test the hy-
pothesis of no difference in the population distributions of achievement test scores
versus the alternative that they differ in location; that is, at least one of the distribu-
tions is shifted above the others. Conduct the test using the Kruskal-Wallis H-test
with a = .05.
