The Kruskal-Wallis Test Statistic Can Be Approximated by a Chi-Squared

question 18

Short Answer

The Kruskal-Wallis test statistic can be approximated by a Chi-squared distribution with k - 1 degrees of freedom (where k is the number of populations) whenever the sample sizes are all greater than or equal to: $\begin{array}{|l|l|}\hline \text { A. } & 30 \\\hline \text { B. } & 20 \\\hline \text { C. } & 10 \\\hline \text { D. } & 5 \\\hline\end{array}$
