Each pair student t vs tukey
WebProcedure Purpose; Student's t (Fisher's LSD) Compare the means of each pair of groups using the Student's t method. When making all pairwise comparisons this procedure is also known as unprotected Fisher's LSD, or when only performed following significant ANOVA F -test known as protected Fisher's LSD. 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 …
