In Chapter 16, We Presented the Data from an Independent

Multiple Choice

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 here. 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. What do you conclude, using a = 0.05?

A) retain H₀ . There is no difference in the populations.
B) accept H₀ . There is no difference in the populations.
C) reject H₀ . At least one of the population means differs from at least one of the others.
D) reject H₀ . At least one of the distributions differs from at least one of the others.
