6.108 An adjustment for multiple tests. One way to deal with the problem of misleading P-values when performing more than one significance test is to adjust the criterion you use for statistical significance. The Bonferroni procedure does this in a simple way. If you perform two tests and want to use the α = 5% significance level, you would require a P-value of 0.05/2 = 0.025 to declare either one of the tests significant. In general, if you perform k tests and want protection at level α, use α/k as your cutoff for statistical significance. You perform six tests and obtain individual P-values of 0.075, 0.021, 0.285, 0.002, 0.015, and <0.001. Which of these are statistically significant using the Bonferroni procedure with α = 0.05?
