Tukey's test

Tukey's test is a statistical method used to compare the means of different groups to see if they are significantly different from each other. It is often applied after an analysis of variance (ANOVA) when you find that at least one group differs. Tukey's test helps to identify which specific groups have differences by calculating confidence intervals for the differences between group means. This helps researchers understand not just that differences exist, but where they lie, making it easier to draw conclusions about data in studies ranging from agriculture to medicine.
