We will give you the Wilcoxon rank-sum test formula along with astep-by-step explanationof how to calculate the Wilcoxon rank-sum test. Once the basics are clear, we dive into the question ofwhen to use the Wilcoxon rank-sum testand discuss the interpretation of the Wilcoxon rank-sum ...
The Wilcoxon test is anonparametrictest designed to evaluate the difference between two treatments or conditions where the samples are correlated. In particular, it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-tes...
Wilcoxon Signed-Rank test(go to the calculator) Wilcoxon Signed-Rank test Calculator When to use? The test usually comes as a failsafe option to a paired t-test when the test doesn't meet the normality assumption or contains many outliers. ...

Paired t-tests and Wilcoxon signed rank tests need, just like multivariate data, more than a single outcome variable. However, they cannot assess the effect of predictors on the outcomes, because they do not allow for predictor variables. They can only test the significance of difference between...
