Webprocedure is widely used for pairwise multiple comparisons in one-way ANOVA. It provides exact simultaneous pairwise confidence intervals (SPCI) for balanced designs and conservative SPCI for unbalanced designs. In this paper, we will extend Tukey's procedure to two-way unbalanced designs. Both the exact and the conservative methods will be ...

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 WebFor a 95 percent overall confidence coefficient using the Bonferroni method the t-value is t.05/4;16 = t.0125;16 = 2.473. Now we can calculate the confidence intervals for the two contrasts.For C 1 we have confidence limits -.5 ± 2.473 (.5158) and for C 2 we have confidence limits .34 ± 2.473 (.5158). Thus, the confidence intervals are: WebThe Tukey method applies simultaneously to the set of all pairwise comparisons {m i -m j} The confidence coefficient for the set, when all sample sizes are equal, is exactly 1-a. For unequal sample sizes, the confidence coefficient is greater than 1-a. In other words, the Tukey method is conservative when there are unequal sample sizes. the boy wizard shop york
