研究人员往往对研究结果的不平等约束方面的期望，例如，组意味着。以研究者为例，他们调查了在具有攻击性的男孩中诱发负面情绪状态的影响。一般来说，高攻击性的男孩在对其他同龄人的攻击性反应上的得分高于中等攻击性的男孩，而中等攻击性的男孩又高于非攻击性的男孩。在大多数情况下，零假设检验用于评估这些假设。然而，我们发现，假设制定使用组之间的不平等约束的手段，一般没有得到适当的评价。错误的假设被测试，即。组均值相等的零假设。在本文中，我们使用贝叶斯模型选择提出了上述问题的创新解决方案，并通过案例研究进行了说明。
Researchers often have expectations about the research outcomes in regard to inequality constraints between, e.g., group means. Consider the example of researchers who investigated the effects of inducing a negative emotional state in aggressive boys. It was expected that highly aggressive boys would, on average, score higher on aggressive responses toward other peers than moderately aggressive boys, who would in turn score higher than nonaggressive boys. In most cases, null hypothesis testing is used to evaluate such hypotheses. We show, however, that hypotheses formulated using inequality constraints between the group means are generally not evaluated properly. The wrong hypotheses are tested, i.e.. the null hypothesis that group means are equal. In this article, we propose an innovative solution to these above-mentioned issues using Bayesian model selection, which we illustrate using a case study.
