Correlations between subjective and genital arousal for men by type of correlations (selected samples)

	Within-subject	Between-subject	Mixed
Average effect size (r)	.91	.62	.66
95% confidence intervals	.70 to 1.12	.46 to .78	.28 to 1.04
Samples (K)	12	28	7
Sample size (n)	164	731	105
Number of studies	10	21	6
Homogeneity (Q)	14.3	91.4	16.5
	p = .22	p < .0001	p < .05

Note: Selected studies refer to basic samples, without experimental manipulations, and with standard external sexual stimuli. A significant Q value means that effect sizes are not homogeneous, suggesting the presence of one or more moderator variables
