Table 1. Principal assumptions tests for regression model diagnostics

Principal Assumptions Tests		Residual	Significant 2-tailed (Spearman’s rho)	Tolerance	VIF	DW
Normality (Kolmogorov-Smirnov)		0.900*
Heteroscedasticity
	Students’ autonomous motivation		0.442*
	Tutors’ autonomy support for students		0.161*
Multicollinearity
	Students’ autonomous motivation			0.559^†	1.790^‡
