Mean vs median and blogs
Seth was making a point on the measures of central tendency, specifically how the mean page views by a blog visitor might not be the best indicator of a typical visitor to your blog.
I made these graphics for a lecture I'll be giving about medical statistics, to give a description view of the two types of skewed distributions. The first, the negatively skewed distribution is what Seth is talking about where the mean has a lower value than the median. In the second, the positively skewed distribution, you might think about the distribution of income in a particular country. [NB: the actual values of mean and median were were not calculated. The mode is what it is, the value with the greatest frequency.]
