Increasing the probability of a Type I error by one percent decreases the probability of a Type II error by one percent.

Question

Quizplus · Accepted Answer

Increasing the probability of a Type I error does not necessarily decrease the probability of a Type II error. The two types of errors have a tradeoff relationship, where reducing one type of error typically increases the other. However, there are occasions where increasing the probability of a Type I error may have no effect on the probability of a Type II error, or could even increase the probability of a Type II error.
