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.

Cohen’s paper The Earth is Round (p>0.05) is a critique of null-hypothesis significance testing (NHST). In his article, Cohen presents his arguments about what is wrong with NHST and suggests ways in which researchers can improve their research, as well as the way they report their research. Cohen’s main point is that researchers who use NHST often misinterpret the meaning of p-values and what can be concluded from them (Cohen, 1994). Cohen also shows that the NHST is close to worthless. NHST is

probability of a statistical study depends on the prior probability, statistical power, and the level of the observed P value, it means that the probability of a study finding a true relationship is the power of 1-β (one – type two error (Ioannidis, 2005 page 0696). Also, “type 1 error is the probability of incorrectly rejecting a null hypothesis that should not be rejected” (Wirtz, 2013). Factors that negatively affect the probability of true relationships are small studies, smaller effect sizes, in
