size bell curve stats

According to the following website, http://www.edu. uni-klu.ac.at/~ … ck/answer19.htm ,
"statistics on erect penis lengths for white college men, in quarter-inch lengths measured by The Alfred C. Kinsey Institute for Sex Research (from the point where the penis meets the body along the top to its tip),"
indicate the following:

0.2 percent 3.75 inches
0.3 percent 4 inches
0.2 percent 4.25 inches
1.7 percent 4.5 inches
0.8 percent 4.75 inches
4.2 percent 5 inches
4.4 percent 5.25 inches
10.7 percent 5.5 inches
8 percent 5.75 inches
23.9 percent 6 inches
8.8 percent 6.25 inches
14.3 percent 6.5 inches
5.7 percent 6.75 inches
9.5 percent 7 inches
1.8 percent 7.25 inches
2.9 percent 7.5 inches
1 percent 7.75 inches
1 percent 8 inches
0.3 percent 8.25 inches
0.3 percent 8.5 inches
0.1 percent 8.75 inches
0.1 percent 9 inches

Anyone know of similar bell curve data on circumference?

Search the forum, I’ve seen at least 10 threads on this. There are probably more. Use AND OR to refine your search. There are some local surveys too.

Interesting.

What interests me about the Kinsey study is the upward jump between 6.25 and 6.5 inches, 6.75 and 7.0 and 7.25 and 7.5. It makes me think that this was a self reported study.

23.9 percent 6 inches
8.8 percent 6.25 inches
14.3 percent 6.5 inches
5.7 percent 6.75 inches
9.5 percent 7 inches
1.8 percent 7.25 inches
2.9 percent 7.5 inches

The other studies I have seen, for example the lifestyles condom study seem to fit a normal distribution better. There are several other threads on in this forum about these studies. Here is one thread with multiple links to different studies: Penis Size: The True Average

Yep. I’ve never heard a guy running his mouth about how big his dick is use anything other than a whole number or “and a half”. Never heard, “Oh yeah, well mine’s 7 and 3/16 mother fucker!” LOL

Yup HughG. No one ever rounds down in a penis-size survey. You can bet that that is one source of distortion in self-reports, along with plain lying and/or self-delusion.

Yes, the full inch and half inch increments being the largest percentages is also suspicious.
