Mann-Whitney U Test Calculator

Calculates the Mann-Whitney U statistic, a non-parametric test used to compare two independent samples. This statistical method assesses whether two sets of data come from the same population or if they originate from different distributions. Users input paired observations into the tool, and it processes these values to determine the magnitude of the difference between the groups. The resulting U value helps quantify the evidence against the null hypothesis that the two populations are identical. Researchers and analysts utilize this calculator when their data fails to meet the assumptions required for parametric tests, such as normality or equal variance. Specifically, students in biology, psychology, and social sciences often use it to compare median differences between groups.
