		X1	X2	X3
X1	Pearson Correlation	1	.303**	.183*
	Sig. (2-tailed)		.000	.000
	N	500	500	500
X2	Pearson Correlation	.303**	1	-.441**
	Sig. (2-tailed)	.000		.032
	N	500	500	500
X3	Pearson Correlation	.183*	-.441**	1
	Sig. (2-tailed)	.000	.032
	N	500	500	500

** Correlation is significant at the .01 level (2-tailed).

* Correlation is significant at the .05 level (2-tailed).
