1 NHST [Preventing abusive practice, critics and claims to ban NHST´s from scientific literature] I do not need, sure, to add further reasons than the following one to agree that the condition pvalue < = alpha strongly suggests that the Null Hypotheses, H0, is false. In fact one is enough: if so all pvalues do follow a Uniform Distribution in [0, 1], so alpha, ordinary set 0.05, is the probability that the statement H0=true is indeed false. After presetting alpha and performing the test, if: ____pvalue > alpha, we did not get sufficient evidence to reject the Null Hypotheses, H0, ____pvalue <= alpha we reject H0 with the probability 1alpha confidence, therefore alpha level of significance.
