When performing an Analysis of Variance and finding a statistically significant interaction a post hoc test is often performed to find where the difference lies. Special additional tests to correct the alpha level are utilized to a. Assess the effect size b. Protect against making a Type I error c. Protect against making a Type II effort d. Test for heteroscedasticity
