Mean versus Median for those of you interested in statistics
Everything I have read on this forum always references the “average” penis size. “Average” is just the layman’s term for “mean” which is statistically useful if the data is follows a normal distribution. Normally distributed data looks like a bell curve when shown on a graph. I have to assume that penis length data cannot be normally distributed because a penis cannot be smaller than zero, but there is no upper limit on how long a penis can be (at least theoretically). When graphed, this type of data looks like a bell that leans to the left.
A good example of non-normally distributed data would be housing prices. A town may have hundred of homes that sell in the $150K to $300K range, but there are also a handful $500K homes, and a few million-dollar homes. The million-dollar homes cause the average (mean) home value to be much higher than what is really the “middle” home price, so when you hear people talking about home prices, they talk about the “median” home price, not the “average” home price. The median is the middle point of a data set; 50% of the values are below this point, and 50% are above this point. That is not the same as the mean, although the mean and median can be the same if the data is normally distributed.
OK, sorry for the long explanation, but some people don’t understand the difference, and I just wanted to make sure we’re all on the same page. As I said, since penis length is probably not normally distributed data, all of this talk about average penis size is misleading. The average is being influenced by a relatively small number of really long dicks. The influence of the really long dicks is not offset by really small dicks, because a dick can only be so small. The average dick size is may be 5.88 inches, but that doesn’t mean that if you have a 5.88 inch dick, half of the other dicks are bigger than yours. Most likely, if you have a 5.88 inch dick, your dick is bigger than the median, and you are bigger than most others.
So, here’s the question (finally): Where can I get my hands on the raw data that the Kinsey study, and other have used to determine the average penis size? I work with statistics and I have some cool programs that I can plug the data into to learn all kinds of cool stuff. Most importantly, I would like to find out if the data is normally distributed, and if not, let’s talk about median penis size rather than average penis size.
