The Shape, or Distribution, of a Batch

Abstract

The shape of a batch refers to the way in which the numbers are distributed along the number scale, apart from level and spread. The traditional statistical term for shape is distribution. There are two principal aspects to the shape of a batch: number of peaks and symmetry. We have already discussed batches with multiple peaks and some of the reasons why they must be divided before analysis, so we will proceed directly to the second aspect.
