Test variante:

This online calculator provides an implementation to solve the exact permutation of the Wilcoxon-Mann-Whitney test, using the Wilcoxon rank-sum test. The exact solution is provided for tied and non-tied data sets.

In order to start the test, enter your sample data (use whitespaces to separate the elements), choose the test variant and click the "Run"-button. As alternative to filling in the sample data manually, you could upload a CSV file with your data. After selecting your file, the data will be pasted into the form and you can execute the test variant that suits to your input.

To get an impression how the tool works, you can run a sample calculation. Just click on this link and execute the two-sided variant of the test. The result will be displayed below the "Run"-button. If you want to have more information to this specific data set read this paper.
