Probability: α Type II error: the null hypothesis is wrong (and the distribution is somewhere else), but we get a sample statistic that makes us fail to reject H0. WebFinally, because of the relationship between Type I and Type II errors, they're always intention with each other, significance level also impacts the power of a study. For a fixed sample size, effect size, and within-group variability, a higher Alpha means a lower Beta and thus a higher power.
