Webconfidence level: If we want overall level 1- α, then choose individual level 1-α/m. For example, if we are forming 5 confidence intervals and want an overall 95% confidence level, then we need to use the procedure for individual 99% confidence intervals. This method of forming simultaneous confidence intervals is called the Bonferroni method. It Web“B” in Figure 1 are Loftus and Masson confidence intervals. 62 These confidence intervals are much tighter and better reflect our conclusions from the t-test analysis. Loftus and Masson's method has two primary drawbacks: First, all CIs are the same size, so any heterogeneity of variance is hidden; second, it may be ...

Webprocedure is widely used for pairwise multiple comparisons in one-way ANOVA.

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 … cabinet refinishing cleveland ohio
