Table 5 Correlations and multicollinearity between perceived abilities and interests

Variable names	1	2	3	4	VIF	Tolerance
1. Perceived mathematical ability	1.00				1.53	0.65
2. Perceived scientific ability	0.37	1.00			1.53	0.65
3. Math interest	0.51	0.19	1.00		1.42	0.70
4. Science interest	0.18	0.51	0.27	1.00	1.42	0.70

N = 11,560. Variance inflation factor (VIF) was obtained from OLS regression to test for potential multicollinearity. N was rounded to the nearest ten, to comply with NCES restricted-data regulations
