TLDR
The comparison of two treatments generally falls into one of the following two categories: (a) a number of replications for each of the two treatments, which are unpaired, or (b) we may have a series of paired comparisons, some of which may be positive and some negative as mentioned in this paper.Abstract:
The comparison of two treatments generally falls into one of the following two categories: (a) we may have a number of replications for each of the two treatments, which are unpaired, or (b) we may have a number of paired comparisons leading to a series of differences, some of which may be positive and some negative. The appropriate methods for testing the significance of the differences of the means in these two cases are described in most of the textbooks on statistical methods.read more

Nonparametric Tests of Interaction in Experimental Design
TL;DR: In this article, a review of the use of nonparametric analysis of variance in the design of experiments in the behavioral and social sciences that focused on interaction effects is presented, where the authors show that non-parametric methods lack statistical power and that there is a paucity of techniques in more complicated research designs.
