> In statistics, the mean and median are both averages, but are technically quite different. The mean is the sum of all items divided by the number of them, while the median is the middle item in the sorted list.

There was an article posted here, one or two years ago, that explained how mean and median are very similar, as they are the values that minimize residuals or the squared of residuals.

I'm sorry I can't find it right now, I hope some other user knows which article I'm talking about and can link it down here, because it is, in my opinion, an excelent read.
