Weberror rate applies to the parallel scenario, even in the presence of a known significant non-null effect. In other words, the weak protection is ineffective in controlling experiment … WebResampling procedures. The procedures of Bonferroni and Holm control the FWER under any dependence structure of the p-values (or equivalently the individual test statistics).Essentially, this is achieved by accommodating a `worst-case' dependence structure (which is close to independence for most practical purposes). http://ericae.net/ft/tamu/altpaper.pdf how to cite an scholarly article apa

Web"Experimentwise" error rate equals "testwise" error rate when only one hypothesis is tested for a given group of people in a study. However, when more than one hypothesis is being tested in a given study with only one sample, the two error rates may not be equal (Thompson, 1994). WebSuppose that instead of performing one statistical test, we perform three such tests; e.g. three tests with the null hypotheses: H 0: μ 1 = μ 2; H 0: μ 2 = μ 3; H 0: μ 1 = μ 3; Note that if you use a significance level of α = .05 for each of the three analyses then the overall significance level is .14 since 1 – (1 – α) 3 = 1 – (1 – .05) 3 = 0.142525 (see Example 6 …
