Bell-Shaped Animals

Adapted from a graphic in Life magazine October 10, 1955 showing speeds of various animals. The artist has displayed the animals sampled on a horizontal scale of speed. There are few slow animals on the left, many more medium speed animals in the middle, and few fast animals on the right. The outline of the cloud of animals shows the essence of a roughly bell-shaped frequency distribution with a little skewness to the right. But take out the elephant and much of the skewness goes away also.
