Looking at the table below, which variables were the most strongly correlated? (Hint: Larger values of Pearson's correlation (ignoring the sign) indicate stronger correlations between variables).

		Work ethic	Annual income	IQ
Work ethic	Pearson's correlation	1.000	.72	.66
	Sig. (2-tail)	.	.001	.000
	N	550	550	550
Annual income	Pearson's correlation	.72	1.000	.47
	Sig. (2-tail)	.000	.	.03
	N	550	550	550
IQ	Pearson's correlation	.66	.47	1.000
	Sig. (2-tail)	.000	.03	.
	N	550	550	550
