讨论了以2 × 2表的形式产生结果的各种类型的专家，并为其中一种类型开发了测试。所考虑的类型是从2个总体中抽取m和n的样本，每个元素都属于2个类别中的一个。经过检验的假设是，一个类别中的比例在两个人群中是相同的。在这种情况下，没有明确的顺序的样本点。根据拒绝区域的凸性、系统性和最大“体积”这3个标准制定了排序。
Various types of expt. giving rise to results in the form of a 2 X 2 table are discussed and a test is developed for one type. The type considered is that in which samples of m and n are drawn from 2 populations and each element classified in one of 2 categories. The hypothesis tested is that the proportions in one category are the same in both populations. In this situation there is no clear-cut ordering of the sample points. An ordering is developed on the 3 criteria of convexity, sytn-metry and maximum "volume" of the region of rejection.
