How to Perform a Tukey Test in R: Post-Hoc Analysis Simplified
This video will walk through you all the steps you need to take to run a one-way ANOVA (Analysis of Variance) in R, without violating any assumptions of the ANOVA. We'll also perform EDA, test for normality, equal variances, and interpret the results.
