Wilcoxon Table Of Critical Values. - z σ - 05 You plug into this formula whatever value of z corresponds to your desired significance level. Table Critical values for the Steel test.
1 The Wilcoxon Rank-Sum Test The Wilcoxon rank-sum test is a nonparametric alternative to the two-sample t-test which is based solely on the order in which the observations from the two samples fall. Wilcoxon Rank-Sum Table Suppose the observed Wilcoxon-Mann-Whitney WMW test-statistics U obs is the smaller of the two calculated rank-sum values U 1 and U 2. Here S is equal to R1 in the definition of U1.
If U obs.
We will use the following as a running example. Or t-test for. The tables on the following pages provide critical values for the Wilcoxon rank-sum test for independent samples with sizes from 3 to 25. The critical value 64 and the decision rule is as follows.
