Length

As seen in Figure 4, a notable difference between the Kinsey and photo length distributions was their divergence in the range containing shorter erections.  The range from 4.5 to 5.75" was occupied by 10% less of the Kinsey distribution (30.8%) than of the photo distribution (40.8%).  The exceptionally high 21.9% of Kinsey respondents who reported a 6" erection length made it possible for the two distributions to be different in most of their lower range and yet for the Kinsey sample to "catch up" and even slightly surpass the photo sample at the midpoint.  The Kinsey census sample and the photo sample had strikingly similar cumulative percents at the 6, 6.25, and 6.5" points on the distribution of lengths.  Still, the photo sample's mean length of 6.05 in. suggests a cautious interpretation of the Kinsey census sample's 6.20 in. mean.  As would be expected by chance alone, the small photo sample lacked representation at the extreme ends of the spectrum. [Please see the page entitled "Related Article" for even greater cautions regarding the photo and Kinsey averages for length.]
