Report sentence:
A Brown-Forsythe homogeneity-of-variance test was conducted to compare the variance of G3 final grades across studytime groups. The result was F(3, 645) = 1.0263, p = 0.3804. Because p >= 0.05, the analysis did not find strong evidence that G3 variance differs across studytime groups.
