Question

Run an appropriate test between the pre-test and post-test data of the experimental group. What is the result of the test? A) W_s = 1.5, z = -4.514, p < .001 B) W_s = -4.514, z = 1.5, p < .001 C) W_s = 1.5, z = -4.514, p = .000 D) W_s = -4.514, z = 1.5, p = .000

Quizplus · Accepted Answer

The correct answer is A because the Wilcoxon signed-rank test is an appropriate test for comparing pre-test and post-test data, and the result of the test is W_s = 1.5, z = -4.514, p < .001.
