WebTukey's method considers all possible pairwise differences of means at the same time: The Tukey method applies simultaneously to the set of all pairwise comparisons $$ \{ \mu_i - \mu_j \} \, . $$ : The confidence coefficient for the set, when all sample sizes are equal, is exactly $1 - \alpha$. For unequal sample sizes, the confidence coefficient is greater than … WebThe confidence interval for the difference between the means of Blend 4 and 2 extends from 4.74 to 14.26. This range does not include zero, which indicates that the difference between these means is statistically significant. The confidence interval for the difference between the means of Blend 2 and 1 extends from -10.92 to -1.41. 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. segieth hehn

"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. In psychology literature, it is often referred to as paired comparison. " - Pairwise statistics
