Wilcoxon Rank-Sum Table

In the following tables n1 is the size of the smaller sample and n2 is the size of the larger sample. See Wilcoxon Rank-Sum Test for details. Note that α for a one-tail test (lower tail) is equivalent to 2α for a two-tail test.

Alpha = .01 (two-tailed)

Wilcoxon Rank-Sum Table, alpha = .01

Alpha = .05 (two-tailed)

Wilcoxon Rank-Sum Table, alpha = .05

Alpha = .20 (two-tailed)

Wilcoxon Rank-Sum Table, alpha = .20
