Note. Because Levene’s test of homogeneity of variances was significant for the TEGI measure, Welch’s Robust Test of Equality of Means (asymptotically distributed F) and follow-up Games–Howell pairwise comparisons are reported. For the NWR, SR, and TNL measures, Levene’s test was not significant; analysis of variance and and Sidak pairwise comparisons are reported. TEGI = Test of Early Grammatical Impairment; NWR = Nonword Repetition task; SR = Sentence Recall task; TNL = Test of Narrative Language.
