Some Cheap Tricks for Making Inferences About Distribution Shapes from Variances.
Messick, David M.
Educational and Psychological Measurement, v42 n3 p749-58 Fall 1982

The uses of the variances of the maximum variance distribution, the uniform distribution and a unimodal triangular distribution to make inferences about distribution shapes are shown in several examples.
