WebJan 14, 2024 · There’s a fairly simple workaround for this situation. I’d use a Bonferroni correction, which involves dividing your significance level by the number of comparisons (e.g., 0.05 / 2 = 0.025). Then, perform two 2-sample t-tests for B vs A and C vs B. For those tests, use the Bonferroni corrected significance level.
