Dunn's Test

Dunn's Test is a statistical method used to compare multiple groups to see if their differences are significant after finding a general difference with an initial test like Kruskal-Wallis. It helps identify which specific groups differ from each other, adjusting for the fact that multiple comparisons are made, reducing the chances of false positives. Essentially, Dunn's Test offers a systematic way to pinpoint specific differences between groups in a reliable manner, often used in research to analyze data that doesn’t assume normal distribution.
