Likelihood-Ratio Test for Gender Difference in Synchronous Relation between Behavioral Engagement and Performance Practice

Model Chi-Square Likelihood-Ratio Test
Model 10 χ2 (df = 62) = 74.88
Model 11 χ2 (df = 68) = 82.43 χ2(Model 11 – Model 10) = 7.55, df = 6, p = .27
Model 12 χ2 (df = 66) = 81.48 χ2(Model 12 – Model 10) = 6.6, df = 4, p = .16
Model 13 χ2 (df = 69) = 82.50 χ2(Model 13 – Model 10) = 7.62, df = 7, p = .37

Note. The likelihood-ratio (chi-square difference) tests are reported in the third column. Model 10 = no equality constraints on the synchronous correlations across either gender or grades; Model 11 = Synchronous covariances are freely estimated within each gender but equated across gender; Model 12 = Synchronous covariances are equated across grades but freely estimated across gender; Model 13 = Synchronous covariances are equated across gender and grades.
