Wilcoxon Signed-Rank Test Calculator

Wilcoxon Signed Rank Test is a popular non parametric test for comparison of matched or paired data to assess whether their population mean ranks differ. The test aims to determine how different two sets are from one another and uses the difference between the sets of pairs to establish statistical significance between the two distributions. It assumes that the pairs in the data come from dependent populations and the given data is continuous as opposed to discrete. Moreover, being a non-parametric test, the model does not require a particular probability distribution of the dependent variable as part of the analysis.
