In order to determine whether the median distance for the X-Special golf ball exceeds the median distance for the best-selling golf ball,six golfers were selected and asked to hit each ball with their driver.The distance was recorded.The following data were observed.
Based on these,the appropriate test is the Kruskal-Wallis one-way analysis of variance.
