It is common to perform experiments in which a 'success' is claimed when the null hypothesis is discarded. However, there is a category of experiment that has become important in which a success is when the null hypothesis is not rejected. Failing to discard the null hypothesis is different from proving it to be valid, a distinction that is particularly important in experiments in which any inadequacy of experimental design or implementation enhances the likelihood of a success. The appropriate analysis of such experiments tests for evidence of the validity of the null hypothesis rather than simply failing to find evidence against it.
当零假设被摒弃时，就宣称取得了“成功”。然而，有一类实验变得很重要，在这类实验中，当零假设未被拒绝时才是成功。未能摒弃零假设不同于证明它有效，在实验设计或实施存在任何不足都会增加成功可能性的实验中，这种区别尤为重要。对此类实验的恰当分析是检验零假设有效性的证据，而不是仅仅未能找到反对它的证据。
