Question

Quizplus · Accepted Answer

This test is used when we have multiple independent groups and we suspect that there is a meaningful order of median values between the groups. Therefore, option C is the correct choice. Option A is incorrect as the Jonckheere-Terpstra test is a follow-up test to the Kruskal-Wallis test and not a substitute for it. Option B is too general and not specific to the conditions required for the Jonckheere-Terpstra test. Option D is incorrect as option C is the correct answer.
