Quick Mann-Whitney U Calculator (Legacy)
A streamlined, lightweight version of the Mann-Whitney U Test designed for rapid hypothesis checking. Ideal for small datasets and quick A/B testing decisions.
About
This is the Legacy/Quick version of our Mann-Whitney tool, stripped down for speed. It is designed for users who need a binary "Yes/No" answer regarding statistical significance without the visual clutter of detailed breakdowns. It is particularly useful for A/B testing scenarios where you need to check if a metric (like time-on-page) differs significantly between two small groups (n < 50) where data is not normally distributed.
