Table 4 Test of homogeneity of variance

		Levene Statistic	df1	df2	Sig
Pretest.sum	Based on mean	0.421	1	59	0.519
	Based on median	0.432	1	59	0.514
	Based on median and with adjusted df	0.432	1	58.873	0.514
	Based on trimmed mean	0.415	1	59	0.522

The results indicate that the difference between the experimental groups is insignificant (sig = 0.519, p > 0.05) and they were homogeneous in terms of intended variables before the treatment
