The (statistical) Truth About Cock Size

I am still unsure about what to believe.

Well 1 and 2 are very likely. The statistics cannot be wrong per se, since they are based on a legitimate data set of sufficient power, but it may be the case that it is not as accurate of a model as it could be, as I addressed in my previous post. Again, this may be due to an insufficiently random sample - the truly short guys may have been unwilling to drop trousers and the truly long gents may have been off using their tools on the hotties.

Statistics are ever only an approximation of a population, which is why I titled this thread as I did.

Cheers!

priap, I thought that the median for the lifestyles was lower than the mean. At least according to wikipedia it is. Same for girth (median was lower). It has charts and everything on there.

The distribution is skewed to the right as, like you said, larger guys would be more inclined to volunteer, which would also increase the mean. It could also be due to the sample size (that the mean and median don’t match) or just that’s how it could be in nature.

Remember that average and median are two different things ..

Taken from the link posted above :

“The average is 5.88”, however the nature of distribution means the average is not the same as most common. This is because the few very long ones, bias things. So the median is 5.65”. That’s the point where 50% will be larger and 50% smaller. It’s the typical size.”

Nice link, Norwegian.

The graph of girth data clearly shows why the irregularity of those data make it difficult to run basic statistics on them.

As for length, at approximately 0.27 standard deviation apart, the mean and the median are really very close. Yes, there is some skewing of the mean due to a few more lengthy guys than shorter guys in the survey, but the effect is modest. I would not consider any of the data points to be outliers. Now if a couple of dudes with 12 inch dicks had walked into that tent…

Hey Ztalin,

You are correct, the median is lower than the mean, as one would expect if largeness equals confidence. Hence, the sample is not truly random, but somewhat influenced by a greater proportion of longer guys getting measured. But, as I said, the effect, i.e. the difference between mean and median, is relatively minor.

To help clarify the issue that Norwegian92 pointed out, here are some fake numbers just to illustrate the point.

Penis length in inches: 2,2,2,3,3,3,3,3,3,3,3,3,4,5,6,7,18,20,20,20

Mean = 6.7 inches, Median = 3 inches

The four elephant dicks are outliers in this data set and so skewed the data well to the right.

Remember, there are three types of lies: lies, damn lies, and statistics :)

For some reason I expected to see Tolka respond to this thread.

This time, measurements were taken by nurses from the point where the penis meets the body (at the pubic bone). The study also found that the average erect penis had a girth of 4.972 inches, with three quarters of dudes measuring between 4.5 and 5.5 inches around.

Still not clear.

1.BP or NBP? I don’t see the sentence ” pressed to the pubic bone”.

2. Drugs induced erection or not?

3. Standing or in sitting position?

Not only that, but he says “3/4 people between 4.5 and 5.5” and when you look at the graph, that isn’t the case. It’s only about 57% between with 34% below 4.5 and 8% above 5.5.

I am not sure that the numbers would be skewed, as when a bunch of horny drunk young guys have a chance to drop their pants for a couple hoties, most would do so.
I mean, when one is drunk they have beer muscles, would it not be the same for beer dick?

I was with a new woman last night, she is known to be a size queen, yet she called my 7 1/2” cock an anoconda. (What does that say for her perception? I am big, or she wanted me to feel good about myself? One may never know!)

I find it real hard to believe that at 7.5X5.6 inches, I am in the 97-98th percentile.


2007-01-27 5.3" BPEL 4.8" EG, Less than 3" Flaccid, and sometimes less than 2"

As of 12-07-2008 7.75" BPEL 7.1" NBPEL 5.7"MSEG 6"+ BSEG. Ultimate goal 8+ inches NBPEL, 8.5" BPEL 6.3" EG (2" diameter just sounds so cool!)

Flaccid 5+ inches on a good day. 4 1/2+ pretty much anytime. My gains have slowed to a snails pace, but I will not quit!!!!!!!

These women are most likely “guesstimating” from the bottom. “Measuring” from top-ish of scrotum to the glans. At least that is my theory.

Porno movies are not a good statistical sample of what’s out there, if that’s your frame of reference (just assuming and you know what they say about assume). If everyone were hung like a porn star, we wouldn’t have to see the same old jackasses in almost every scene.

you’re 7.5 BPEL. I doubt that the Lifestyles survey was BP, but I do think that the average for the NBPEL was skewed up a bit from non-random sampling.

You’re assuming that everyone was drunk enough to not have insecurities. I don’t get like that when drunk.

If it was NBPEL, the average would be skewed up by 1/2” at least. That’s a big amount for penises. The next highest average NBPEL is 5.35”.

Measuring of length was from the point at the base of the erect penis where the top of the penile shaft meets the pubic area
to the tip of the glans (“head”).

Sounds NBP to me.

Things suggest to me that it is either BPEL or kinda BPEL. Unfortunately we will probably never know because Lifestyles never published the study.

But at some point we just have to move on and stop obsessing.

If you think it is NBPEL, then add some different figures to account for fat pad — .25 to .5 seems to be the “majority” range around here.
