How can we get the critical value for the Kruskal-Wallis test?
Determine the degrees of freedom and alpha level
Determine the sample size
Determine the sample size and the alpha level

Do not reject
Reject
What does it mean when the null hypothesis is not rejected?
There is significant difference
There is no significant difference
If the computed H-statistic is greater than the critical chi-square value, what should we do with the null hypothesis?
Do not reject
