In Chapter 16, we presented the data from an independent groups design and asked if it was appropriate to use parametric ANOVA. The data are presented again below. The correct answer was that it was not appropriate to use parametric ANOVA because of unequal n s and homogeneity of variance assumption violation. Instead, analyze the data with the Kruskal-Wallis test. Using a = 0.05, H crit = _________.
A) 3.841
B) 7.815
C) 5.991
D) 7.824
