Repeat Exercise 2 using the Kruskal-Wallis H test, and compare these results to the corresponding ANOVA results.

Data from exercise 2

Using the means and standard deviations you have already calculated for the data from the four dormitories (i.e., Turck, Dirk, Dupre, and Doty Halls), perform an analysis of variance to decide whether you can reject the null hypothesis that the four samples come from populations with identical means. Calculate eta squared for this comparison, and comment on the proportion of variance accounted for by the different dormitories.
