A multiple comparison rank sum test, for the simultaneous comparison of all pairs of treatments in a one-way classification with equal numbers of observations, is presented. An example is worked and… Expand

Problems of applied research have necessitated the investigation of multiple comparison procedures. Such investigations have been carried out almost entirely within the framework of the analysis of… Expand

Tables are presented for a multiple comparisons sign test comparing each treatment with a control. An illustration of the test procedure is provided, and the tables are also used to construct… Expand

Let (Xoj, X1j, …, Xkj) be the result of a single trial, where the subscripts o is associated with a control and the subscripts 1, …, k with treatments. To test the joint hypothesis P(Xij – Xoj >… Expand

A number of nonparametric tests based on ranks have been proposed for the comparison of treatments in a completely random design. For example, we have the Wilcoxon-Mann-Whitney test [21, 10],… Expand
