Practice: ANOVA

In this practice exercise, you will use the built-in dataset iris to test whether the Sepal.Length differs by Species. This exercise does not count toward your grade. It is just for practice!

Exercise Instructions:

  • Use the built-in dataset iris to test whether the Sepal.Length differs by Species. 
  • Use a posthoc test with the Benjamini-Hochberg adjustment to test the differences in means of Sepal.Length by Species. 
  • Do the results of ANOVA and the posthoc test agree?
