Abstract

MorePower 6.0 is a flexible freeware statistical calculator that computes sample size, effect size, and power statistics for factorial ANOVA designs. It also calculates relational confidence intervals for ANOVA effects based on formulas from Jarmasz and Hollands (Canadian Journal of Experimental Psychology 63:124-138, 2009), as well as Bayesian posterior probabilities for the null and alternative hypotheses based on formulas in Masson (Behavior Research Methods 43:679-690, 2011). The program is unique in affording direct comparison of these three approaches to the interpretation of ANOVA tests. Its high numerical precision and ability to work with complex ANOVA designs could facilitate researchers' attention to issues of statistical power, Bayesian analysis, and the use of confidence intervals for data interpretation. MorePower 6.0 is available at https://wiki.usask.ca/pages/viewpageattachments.action?pageId=420413544 .

摘要

MorePower 6.0 是一款灵活的免费统计计算器，可用于计算析因 ANOVA 设计的样本量、效应量和功效统计。它还基于 Jarmasz 和 Hollands（加拿大实验心理学杂志 63：124-138，2009）的公式为 ANOVA 效应计算关系置信区间，并基于 Masson（行为研究方法 43：679-690，2011）的公式计算零假设和备择假设的贝叶斯后验概率。该程序的独特之处在于允许直接比较这三种方法对 ANOVA 检验的解释。它具有很高的数值精度和处理复杂 ANOVA 设计的能力，可以促进研究人员关注统计功效、贝叶斯分析以及置信区间在数据解释中的使用。MorePower 6.0 可在 https://wiki.usask.ca/pages/viewpageattachments.action?pageId=420413544 获得。
