Type I error: Frank thinks that his rock climbing … 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 probability of a Type I error. The consequence here is that if the null hypothesis is false, it may be more difficult to reject using a low value for \alpha α.
