... There are several reasons you may wish to have hamster-level statistics. First, you never had a statistics course, or it was so long ago that you were sitting between Fred Flintstone and Barney Rubble. You know that the mean is a bad measure for average income, but aren’t certain why. Perhaps, you h ...
