Assume that 4 populations are to be compared using a Kruskal-Wallis one-way analysis of variance. What is the critical value using a 0.05 level of significance?
A) 5.9915
B) 6.2514
C) 7.8147
D) 9.4877

Question

Quizplus · Accepted Answer

The Kruskal-Wallis test uses the chi-square distribution to determine the critical value. With 4 populations, the degrees of freedom is 3 (number of groups - 1). At a 0.05 significance level, the critical value from the chi-square distribution table with 3 degrees of freedom is approximately 7.8147.
