In the Exercise below, we provide independent simple random samples from several populations where, in each case, all the observations are distinct values. For each exercise, perform the following tasks.
a. Compute the Kruskal-Wallis test statistic, K, by using the defining formula, given in Key Fact 16.5 on page 729. Use the defining formulas when obtaining SSTR and SST for the ranks.
b. Compute the Kruskal-Wallis test statistic, K, by using the computing formula, given in Equation (16.6) on page 730.
c. Compare your results in parts (a) and (b).
d. Explain the fact that parts (a)-(c) are illustrating.
