WebOne needs to compute the SE, the t-statistic, and P-value for each pair of treatments. When there g treatments, there are g 2 = g(g 1)=2 pairs to compare with. I When all groups are of the same size n, an easier way to do pairwise comparisons of all treatments is to compute the least signi cant di erence (LSD), which is the minimum amount Pairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred, or has a greater amount of some quantitative property, or whether or not the two entities are identical. The method of pairwise comparison is used in the scientific study of preferences, attitudes, voting systems, social choice, public choice, requirements engineering and multiagent AI systems.

WebSPSS Statistics generates quite a few tables in its output from a two-way ANOVA. In this section, we show you the main tables required to understand your results from the two-way ANOVA, including descriptives, between-subjects effects, Tukey post hoc tests (multiple comparisons), a plot of the results, and how to write up these results. Web10.3 - Pairwise Comparisons. While the results of a one-way between groups ANOVA will tell you if there is what is known as a main effect of the explanatory variable, the initial results will not tell you which groups are different from one another. In order to determine which groups are different from one another, a post-hoc test is needed.
