Post-hoc power analysis has been criticized as a means of interpreting negative study results.2 Because post-hoc analyses are typically only calculated on negative trials (p ≥ 0.05), such an analysis will produce a low post-hoc power result, which may be misinterpreted as the trial having ...
a post hoc power analysis"A post hoc power analysis"是一种统计分析方法,用于在数据收集后评估一项研究的统计效力。这种分析方法可以帮助研究人员了解他们的研究结果的可信度,并确定研究的有效性。在进行post hoc power analysis时,研究人员需要提供他们使用的样本大小、效应大小以及他们的误差率。然后,他们会使用...
