Quizplus · Accepted Answer

The Kruskal-Wallis Rank Test is specifically designed for situations in which there are more than two groups, making it the appropriate choice over options A and B. It is also a nonparametric test, meaning it does not require the assumption of normality like ANOVA does, making it a better choice than option C. Option D is not relevant as it pertains to related samples, while the Kruskal-Wallis Rank Test is used for independent samples.
