Independent sample t-test and Levene test for pretest scores.

		Posttest score variance equation Levene test		t-test for the mean equation
		F	Sng	t	df	Sng	Mean error	Standard error difference	95% difference confidence interval
									Lower limit	Upper limit
Posttest score	Assuming equal variances	0.367	0.246	−0.245	59	0.825	−0.4217	1.4325	−3.145	2.386
	Assuming that the variances are not equal			−0.236	54	0.825	−0.4217	1.4325	−3.145	2.386
