1.Table 8 of the appendix in the textbook shows critical values for different sample size and study design with 3, 4, or 5 groups.

2.As seen in the formula, there is a separate numerator and denominator calculation for each group.

3.In this example, the test statistic, H-value, of 7.52 exceeds the critical value of 5.66, so we reject the null hypothesis.
