Nonparametric tests employ alternatives such as sequentially ranking observations from all groups or comparing two groups observation by observation to test hypotheses. These are unlike parametric tests that estimate the parameters of normally distributed data, then perform a computation on these estimates. In other words, it tests the hypothesis that two or more groups all come from the same distribution against the alternative that at least one of the group s comes from a different distribution. Included with the test statistic is a table displaying the mean rank for each of the groups that can be used to assist in determining w hich group tends to have larger values than the others. Using the Kruskal-Wallis Test, a significant difference was found between conditions 1 through 4 for object recognition after watching the scrolling key frames one time through.
