You want to test whether the population distributions of the number of goals scored in all competitions are the same for the 90 European clubs. Because you don't have much time, you select a random sample of 10 matches for each club with a name starting with the letter A to L and a random sample of 15 matches for each club with a name starting with the letter M to Z. If you use the Kruskal-Wallis test, what is the degree of freedom?
