A Mann-Whitney U test is used to compare the differences between two independent samples when the sample distributions are not normally distributed and the sample sizes are small (n <30). It is considered to be the nonparametric equivalent to the two-sample independent t-test.

**Tutorial: ** Mann-Whitney U Test

To conduct a Mann-Whitney U test for two independent samples, simply enter the data values below and click the “Calculate” button.

This calculator just works fine!

When I enter the data values in the boxes (I tried hitting enter and putting them on separate lines, separating by commas, and simply separating by spaces) and hit the calculate button, nothing happens.

Thank you
