Mann-Whitney U Test Calculator
Introduction & Importance
The Mann-Whitney U test, also known as the Wilcoxon rank-sum test, is a non-parametric test used to compare two independent samples. It’s important because it doesn’t assume the data is normally distributed, making it a versatile tool for various research fields.
For more information, see the NIST’s guide on the Mann-Whitney U test.
