9. ANCOVA assumptions also require that the regression slopes for a covariate are homogeneous. T F

10. The sixth assumption for ANCOVA is that the covariate is reliable and is measured without error. T F

11. The assumption of homogeneity of variances is best tested through the use of Levine’s test. T F

12. The assumption of linearity is more precisely tested by obtaining and examining residual plots between the covariates and the IVs. T F

13. Regression is incorporated into ANCOVA in order to predict scores on the DV based on knowledge of scores on the covariate. T F

14. A violation of the assumption of homogeneous regression slopes is crucial with respect to the validity of the results of ANCOVA. T F

15. The null hypothesis being tested with the assumption of homogeneity of regression slopes is that all regression slopes are equal. T F

16. The logic of ANCOVA is identical to the logic behind ANOVA. T F
