Abstract: Results of practical importance had been discarded testing formulated hypothesis with the aid of statistical analysis of experimental data because of the power of the utilized test. This study compares the power of two Bonferroni's Modified and one Sidak's Modified tests with known tests analyzing 1200 simulated experiments. All differences of means were obtained in relation to the mean of the adopted control to guarantee parametrical magnitude of mean differences. Student's test (type I comparisonwise error) … Show more

“…Esses testes têm, portanto, menor poder. Em contraposição, os testes que controlam o nível de significância por comparação são mais liberais, porque rejeitam a hipótese da nulidade com mais facilidade, mas têm grande poder, pois nível de significância e poder do teste crescem juntos 20,21 .…”

“…The most popular tests for mean separation that are resistant to multiple testing are for example Fisher's protected LSD, Tukey's HSD, Scheffé's, Duncan's and Neuman-Keul's tests. Researchers still work on multiple comparison procedures (e.g., Barbin,, 2006 andConagin et al, 2008).…”

“…A similar procedure employed for the BM 2 and siM tests (Conagin & Barbin, 2006a, 2006b) can be used here. The first modification here proposed for the Tukey test, called TuM 1 , is to carry out all the preliminary phases made for BM 2 and siM and determine â, an estimate of the number of significative differences a.…”
