THE PERCEPTIONS AND USAGE OF STATISTICAL POWER IN APPLIED PSYCHOLOGY AND MANAGEMENT RESEARCH
评估了七本顶级期刊中应用心理学与管理研究文章的统计功效水平，调查了作者对统计功效分析的认知和使用情况，发现功效分析不常进行、研究者认为需求低且已发表研究功效低。
We first assess the current level of statistical power across articles in seven leading journals that represent a broad sample of applied psychology and management research. We next survey the authors of these articles to examine their perceptions and usage of statistical power analysis. Finally, we examine the perceptions and usage of power analysis in a survey of authors of regression‐based research appearing in leading journals. Findings from the assessment of power and surveys of researchers indicate that power analyses are not typically conducted, researchers perceive little need for statistical power, and power in published research is low. We conclude by discussing implications of low power for the field and recommending avenues for improving researchers' awareness and usage of statistical power.
