Excel has the necessary built-in statistical functions to conduct Scheffé, … The method of pairwise comparisons. The degrees of freedom is equal to the total number of observations minus the number of means. Compute p for each comparison using the Studentized Range Calculator. If ANOVA indicates statistical significance, this calculator automatically performs pairwise post-hoc Tukey HSD, Scheffé, Bonferroni and Holm multiple comparison of all treatments (columns). Online statistics calculator to test the Tukey post hoc Honestly Significance Difference (HSD) using one-way ANOVA method. For this experiment, df = 136 - 4 = 132. ... Grouping Information Using the Tukey Method and 95% Confidence Paint N Mean Grouping Blend 4 6 18.07 A Blend 1 6 14.73 A B Blend 3 6 12.98 A B Blend 2 6 8.57 B Means that do not share a letter are significantly different.

This method of pairwise comparisons is like a "round-robin tournament". We present a different one here, just to keep you on your toes. Studentized Range Calculator $$ : The confidence coefficient for the set, when all sample sizes are equal, is exactly \(1 - \alpha\). Pairwise comparisons for One-Way ANOVA. For unequal sample sizes, the confidence coefficient is greater than \(1 - \alpha\). The text presents one version of the method of pairwise comparisons. Tukey'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 \} \, . For each pair of candidates (there are C(N,2) of them), we calculate how many voters prefer each.
