![]() ![]() ![]() The Kruskal-Wallis test uses ranks of the original values and not the values themselves. That's appropriate in this case, because the scale used by the taste-testers is ordinal. First, each case is ranked without regard to group membership. Cases tied on a particular value receive the average rank for that value. After ranking the cases, the ranks are summed within groups. |
