Dunn Test

The Dunn Test is a statistical method used to compare multiple groups to see if their differences are significant after finding overall differences with a test like ANOVA. It specifically helps identify which groups differ from each other. Imagine comparing several treatment options to see if one is more effective than another. The Dunn Test performs pairwise comparisons between groups while adjusting for the fact that multiple comparisons increase the chance of false positives. This ensures the results are reliable and helps pinpoint exactly which groups differ in a statistically meaningful way.
