WebbThe level of significance, α, is the probability of committing a Type I error, rejecting the null hypothesis when it is, in fact, true. D. The level of significance, β, is the probability of committing a Type II error, rejecting the null hypothesis when it is, in fact, true. 2. WebbOn a more crude level if your alpha level was 1 you would always detect an effect and beta would be 0, while if alpha was zero you'd never detect an effect and beta would be 1.
WebbBecause we are setting \(\alpha\), the probability of committing a Type I error, to 0.05, we again reject the null hypothesis when the test statistic \(Z\ge 1.645\), or equivalently, … WebbA Type I error is when we reject a true null hypothesis. Lower values of \alpha α make it harder to reject the null hypothesis, so choosing lower values for \alpha α can reduce the …

WebbWhen considering several hypotheses, the problem of multiplicity arises: the more hypotheses are checked, the higher the probability of obtaining Type I errors (false positives). The Holm–Bonferroni method is one of many approaches for controlling the FWER, i.e., the probability that one or more Type I errors will occur, by adjusting the …
