How to perform an ANOVA and post-hoc tests using R

This blogpost provides a tutorial on performing an ANOVA analysis using R for the Psych Rstats Club. ANOVA, an extension of the two-sample t-test, examines differences among means of multiple groups. Using the iris dataset, the tutorial covers assumptions, tests for normality and homogeneity of variances, ANOVA analysis with base R, post-hoc tests like Tukey\'s HSD, Bonferroni, and Holm corrections, and the rstatix package for simplified analysis.
