Sorry, but I know perfectly well what an average is. And median, mode, standard deviation, skew, kurtosis, and what a t-test is, what a mancova is and how to interpret beta weights. So, when I receive 30 emails per day, and people in my environment do not seem quite close to that mark, that makes me suspicious. My whole point was that the number is probably inflated. Now, about averages: open your mailbox and compute how many emails you got in the last, say, week? That number should be around 1000. Doesn't that sound too high?
