WebThe normalized contrast, using sums, for the Scheffé method is 4.413, which is close to the maximum contrast. Scheffe preferred when many contrasts are of interest: In the general case when many or all contrasts might be of interest, the Scheffé method tends to give narrower confidence limits and is therefore the preferred method. Webuse Scheffe's pair wise multiple comparison method. The first step of Scheffe's method is to obtain the absolute values of pair wise differences between sample means. Recall that …

Scheffé's method is a single-step multiple comparison procedure which applies to the set of estimates of all possible contrasts among the factor level means, not just the pairwise differences considered by the Tukey–Kramer method. It works on similar principles as the Working–Hotelling procedure for … See more In statistics, Scheffé's method, named after the American statistician Henry Scheffé, is a method for adjusting significance levels in a linear regression analysis to account for multiple comparisons. … See more Frequently, superscript letters are used to indicate which values are significantly different using the Scheffé method. For example, when mean values of variables that have been analyzed using an ANOVA are presented in a table, they are assigned a different letter … See more Let μ1, ..., μr be the means of some variable in r disjoint populations. An arbitrary contrast is defined by $${\displaystyle C=\sum _{i=1}^{r}c_{i}\mu _{i}}$$ where See more If only a fixed number of pairwise comparisons are to be made, the Tukey–Kramer method will result in a more precise confidence interval.
