> Not to be picky but, from what I recall from statistics the mode should be the greatest number of posts on a given day of the month or 242.The mode is the value with the greatest frequency scored. In this case, a single post was recorded by the greatest number of individual posters.
You'll note that the standard deviation is greater than the actual mean value. This indicates that lower frequencies of posting are most common. The data exhibit homoskedacity (skewed to one side, the higher frequencies).
> Also, why isn't the figure for the number of posts per day (87.6) the same as the mean (23.5)?

> TophMean posts per poster per month is 23.5. Mean posts per day of all posters together is 87.6.
