Applying the Bonferroni method. We apply the Bonferroni multiple-comparisons procedure with ⍺ = 0.05 to the data from the Facebook friends study. Given 10 comparisons of interest, the value of t** for this procedure uses ⍺ = 0.05/10 = 0.005 for each test. From Table D, this value is 2.63. Of the statistics t12 = −3.59, t23 = 1.11, and t25 = 2.90 calculated in Example 12.24, only t12 and t25 are significant. These two statistics compare the profile of 302 friends with the two extreme levels.
