Four brands of baseball bats were tested to determine which bat allowed hitters to hit a baseball farthest. Eight different batters were thrown 25 pitches while hitting with each of the four bats (assigned in random order). The median distance of the five longest hits using each bat is shown in the table below. The goal is to determine if a difference exists in the population of median distances for each of the four brands of baseball bat.

What type of nonparametric analysis should be used?
◦ The Kruskal-Wallis H-Test
◦ The Wilcoxon Signed Rank Test
◦ The Wilcoxon Rank Sum Test
◦ The Friedman F_r-Test
◦ The Sign Test
