心理学家必须能够测试是否存在效果和是否没有效果。除了对零进行测试外，研究人员还可以使用两个单侧测试(TOST)程序来测试等价性，并拒绝存在最小感兴趣效应量(SESOI)。Tost程序可以用来确定观察到的效应是否出人意料地小，因为真实的效应至少和SESOI一样极端。我们解释了在心理科学中确定SESOI的一系列方法，并提供了如何执行和报告等价性测试的详细例子。等价性检验是心理学家目前使用的统计工具的一个重要扩展，使研究人员能够证伪关于存在有意义的影响的预测，并宣布没有有意义的影响。
Psychologists must be able to test both for the presence of an effect and for the absence of an effect. In addition to testing against zero, researchers can use the two one-sided tests (TOST) procedure to test for equivalence and reject the presence of a smallest effect size of interest (SESOI). The TOST procedure can be used to determine if an observed effect is surprisingly small, given that a true effect at least as extreme as the SESOI exists. We explain a range of approaches to determine the SESOI in psychological science and provide detailed examples of how equivalence tests should be performed and reported. Equivalence tests are an important extension of the statistical tools psychologists currently use and enable researchers to falsify predictions about the presence, and declare the absence, of meaningful effects.
