Since there are several ways of reducing Type I error, why do researchers not always choose to use all the possible ways to do so? Select the option that is the best reason.
A) Type I error it is actually a good thing because it helps researchers to make important discoveries.
B) Researchers cannot always choose to use a directional hypothesis to reduce Type I error because sometimes they do not know which direction the effect will take.
C) Taking steps to reduce Type I error may increase the risk of Type II error.
D) Researchers are usually more focused on reducing Type II error and are willing to increase Type I error to do so.

Question

Quizplus · Accepted Answer

Taking steps to reduce Type I error may increase the risk of Type II error. Researchers have to balance both types of errors, and reducing Type I error may lead to an increase in Type II error. Therefore, researchers often have to choose a level of significance that balances the risk of both types of errors.
