  1. Suppose there are 6 different treatments with the following sample means:

     

    A

    The Bonferroni multiple comparison procedure conducted 15 hypothesis tests with the following results (D=Don’t Reject Ho and R=Reject Ho):

     

    A

    Order the treatments by their means (from smallest to largest) and draw bars over treatments that are not significantly different.

     

  2. Why is a/g used instead of just a when doing individual hypothesis tests in the Bonferroni multiple comparison procedure?
