Angle
Angle of erection was the second feature analyzed. The mean
angle, in degrees down from vertical, was 65.7º and 74.3º
respectively for the Kinsey census sample and the photo sample.
Both of these means are within the 60-85º interval originally
identified as "average" by the Kinsey team. In the distribution
of angles (Figure 2) one's attention is immediately attracted by
the close agreement between the Kinsey and photo samples in the
30-60º and 60-85º angle intervals, which together account
for over half of all erections. Less agreement was found in
other parts of the distribution. For example, the horizontal
interval, a narrow 10º arc in the total 180º angle spectrum,
was chosen by about 24% of the Kinsey respondents but was less frequently
documented in the photo sample. As a corollary, over 25% of
erections in the photo distribution were observed to be below horizontal,
while very few were reported to be below horizontal in the Kinsey
sample.
Figure 2. Angles Compared Between Kinsey Sample and Photo
Sample When angle and side-view shape were jointly examined (see Figure 3) within the Kinsey census sample, it was clearly manifest that each of the shapes had a different center to its distribution. The straight erections had the same center (60-85º) as the total group, but the center of the n-curve distribution was shifted downward and the center of the u-curve distribution was shifted upward. Despite this variation in central tendency, all shapes had a wide and overlapping range of angles.
