Type I Error Paper

Decent Essays
A type I error occurs when incorrectly rejecting the null hypothesis. The probability of a type I error equals alpha (the level of significance). There is always a possibility of type I error, using multiple t test increase the probability of committing a type I error. Type I errors occur for each t- test, the probability of making type I error from each test will increase. ANOVA is a way to test multiple null hypothesis at the same time. ANOVA test reduces the probability of committing a type I error because the F test is only used once. One test reduces the room for type I errors.
