Mann Whitney U Test Calculate Ranks

Introduction & Importance

The Mann-Whitney U test, also known as the Wilcoxon rank-sum test, is a non-parametric test used to compare the distributions of two independent samples. It’s particularly useful when the data is not normally distributed. This calculator helps you perform the Mann-Whitney U test and understand its significance in statistical analysis.

For more information, see the NIST’s guide on the Mann-Whitney U test and the UNC’s explanation of the Wilcoxon rank-sum test.
