TABLE 5.

F and p values for factors included in two ANCOVAs show treatment significantly improved students’ final course scores and this effect was greater for URM/FG students.

	Treatment	URM/FG	Lab Instructor	Pre-score
Gain Score ANCOVA	F(1, 63)=3.0, p=0.088	F(1, 63)=0.122, p=0.728	F(4, 63)=0.784, p=0.540	F(1, 63)=13.28, p=0.00054
Final Score ANCOVA	F(1, 65)=7.905, p=0.007*	F(1, 65)=4.552, p=0.037 *	F(5, 64)=1.007, p=0.418	—

^*indicates a significant effect of treatment or URM/FG status on the outcome variable.
