Under the heading, “Yet another bad analysis making the rounds,” John Mount writes: This won’t waste much of your time—because there really isn’t much there. But I thought you would be disturbed by this new paper. Here’s my (Mount’s) commentary on what we can surmise about the methods. Mount is pretty scathing.

In 1945, a Cleveland newspaper held a contest to find the woman whose measurements were closest to average. This average was based on a study of 15,000 women by Dr. Robert Dickinson and embodied in a statue called Norma by Abram Belskie. Out of 3,864 contestants, no one was average on all nine factors, and fewer than 40 […]

I wish Napoleon Bonaparte had never been born

Not just for all the usual good reasons why the world needs fewer mass murderers, but also for the very specific reason that, had there been no Napoleon, there’d be no Napoleon-in-Russia graph, then no shining example for Ed Tufte to illustrate how people should make their graphs, then maybe graph-makers wouldn’t all feel that […] The post I wish Napoleon Bonaparte had never been born appeared first on Statistical…

Sanjay's example was a chart that showed medical conditions classified according to the scale "Mild," "Moderate," and "Severe."
