Mann Whitney U Test Calculator Calculator Usage Guide

Learn how to use the Mann Whitney U Test Calculator calculator and its working principles

How to Use the Calculator

  1. Enter the data for Sample 1 in the first input field, separated by commas (e.g., 23, 45, 12, 38).
  2. Enter the data for Sample 2 in the second input field, separated by commas (e.g., 29, 31, 22, 40).
  3. Click the "Calculate" button to perform the Mann Whitney U Test.
  4. The calculator will display the U statistic and the p-value.

Interpreting the Results

The Mann Whitney U Test is a non-parametric test used to compare two independent samples. The U statistic and p-value help determine if there is a significant difference between the two samples.

If the p-value is less than the chosen significance level (commonly 0.05), you can reject the null hypothesis that the two samples come from the same distribution.

Example

Suppose you have two samples:

  • Sample 1: 23, 45, 12, 38
  • Sample 2: 29, 31, 22, 40

After entering the data and clicking "Calculate," you might get a U statistic of 10.5 and a p-value of 0.0321. Since the p-value is less than 0.05, you can conclude that there is a significant difference between the two samples.
