WebIf we took a Bonferroni approach - we would use g = 5 × 4 / 2 = 10 pairwise comparisons since a = 5. Thus, again for an α = 0.05 test all we need to look at is the t -distribution for α / 2 g = 0.0025 and N - a =30 df. Looking at the t -table we get the value 3.03.

WebThe Bonferroni correction compensates for that increase by testing each individual hypothesis at a significance level of , where is the desired overall alpha level and is the number of hypotheses. [4] For example, if a trial is testing hypotheses with a desired , then the Bonferroni correction would test each individual hypothesis at . Webto calculate Chi-square test statistics and p-values for all pairs of groups. Because there are 4 groups, there are 4×3/2=6 pairs and consequently there are 6 comparisons.
