tatistical power is a topic of intense interest as part of proposed methodological reforms to improve the defensibility of psychological findings. Power has been used in disparate ways-some that follow and some that do not follow from definitional features of statistical power. We introduce a taxonomy on three uses of power (comparing the performance of different procedures, designing or planning studies, and evaluating completed studies) in the context of new developments that consider uncertainty due to sampling variability. This review first describes fundamental concepts underlying power, new quantitative developments in power analysis, and the application of power analysis in designing studies. To facilitate the pedagogy of using power for design, we provide web applications to illustrate these concepts and examples of power analysis using newly developed methods. We also describe why using power for evaluating completed studies can be counterproductive. We conclude with a discussion of future directions in quantitative research on power analysis and provide recommendations for applying power in substantive research.

使用不确定的统计功效：设计未来的研究，而不是评估已完成的研究。


统计力量是一个引起人们强烈兴趣的话题，它是为提高心理学研究结果的辩护性而提出的方法论改革的一部分。权力的使用方式多种多样——有些遵循统计权力的定义特征，有些则不遵循统计权力的定义特征。我们在新发展的背景下引入了权力的三种用途的分类法（比较不同程序的性能、设计或规划研究以及评估已完成的研究），考虑了抽样变异性造成的不确定性。本综述首先描述了功率的基本概念、功率分析的新定量发展以及功率分析在设计研究中的应用。为了促进使用功率进行设计的教学，我们提供 Web 应用程序来说明这些概念以及使用新开发的方法进行功率分析的示例。我们还描述了为什么使用权力来评估已完成的研究可能会适得其反。最后，我们讨论了权力分析定量研究的未来方向，并为在实质性研究中应用权力提供了建议。 （PsycInfo 数据库记录 (c) 2024 APA，保留所有权利）。
