I heard Tukey Test can be used for unequal. ANOVA WebP Value from Q Calculator (Studentized Range Distribution/Tukey HSD) The inputs below are straightforward. For example, looking at hours vs. scores is one pairing, sleep vs. scores is another, grades vs. scores is a third and meanwhile, all of those independent variables interact with one another, too. The Tukey Method; The Scheffe Method; The Bonferroni Method; The Holm Method; Example: One-Way ANOVA in R. Suppose a teacher wants to know whether or not three different studying techniques lead to different exam scores among students. If the null hypothesis is computed, you will need to conduct a Post-Hoc test.
