The Wilcoxon Signed Rank Sum Test Table provides statistical data for the Wilcoxon Signed Rank Sum Test, a non-parametric statistical hypothesis test used to compare two related samples, such as samples from the same participants under two different conditions, to assess whether their population mean ranks differ. The table gives the critical values for determining if a difference is statistically significant by rank for samples of a given size at selected significance levels.
