Use a single-test significance level of 05 and observe how the Bonferroni correction affects our sample list of p-values already created. Use a single-test significance level of 05 and observe how the Bonferroni correction affects our sample list of p-values already created. There are a few different approaches that can be taken while conducting these tests ones that are implemented in StatsModels currently are. For example suppose we have three groups A B C and we know ahead of time that were only interested in the following comparisons.
