Abstract
The purpose of this article is to present a set of nomographs for testing the significance of the difference between uncorrelated percentages, and for determining necessary sample sizes when planning studies which will involve the comparison of percentages. Examples of these two uses are given as well as a description of the formula upon which the nomographs are based.Keywords
