Which of the following regarding the assumption of sphericity is false? (Hint: Even very small departures from sphericity produce large biases in the F-test.) Sphericity does not affect post hoc tests. The effect of violating sphericity is a loss of power (i. e., an increased probability of a Type II error). When sphericity is violated, we need to adjust the degrees of freedom for any F-ratios affected by the violation. When sphericity is violated, the Bonferroni post hoc test can be used. 2 points
