There are different tests, I'll let other ... WebBonferroni's method provides a pairwise comparison of the means. To determine which means are significantly different, we must compare all pairs. There are k = (a) (a-1)/2 possible pairs where a = the number of treatments. In this example, a= 4, so there are 4 (4-1)/2 = 6 pairwise differences to consider. To start, we must select a value for ...

WebFinally, proceed as described in Section 7.4.11 by determining adjusted p-values that control the FWE rate when the J groups have a common measure of location.

For example, if we perform three statistical tests at once and wish to use α = .05 for each test, the Bonferroni Correction tell us that we should use αnew = .01667. Within the statistical framework, there are several definitions for the term "family": • Hochberg & Tamhane (1987) defined "family" as "any collection of inferences for which it is meaningful to take into account some combined measure of error". • According to Cox (1982), a set of inferences should be regarded a family: icd 10 code for hypotonia
