在上期推送的G*Power系列中,介绍了点二列相关分析的相关内容。本次推送小编将为大家介绍回归分析的相关内容。回归分析 01 — 简介 回归分析(regression analysis) 指的是确定两种或两种以上变量间相互依赖的定量关系的一种统计分析方法。 02 — 使用步骤步骤 ①...
最后,介绍常见的5种统计力分析(power analysis)的类型。来源:AffectiveNeuroscience-梁丽美 G.Power的功能强大,即可以计算事后统计检验力(事后分析),也可以进行事前样本量的估计(先验分析)。今天,着重讲解一下,如何使用G.power进行各个统计方法的样本量估计?来源:曹振波老师 Tips: 1. 新版的重复测量分析当中,组内相关...
③选择先验分析:在Types of power analysis中选择A priori: Compute required sample size - given α,power,and effect size。 ④输入参数,这里需要注意的是该研究参照了以往的研究进行实验设计,以往的研究均将效应量F置为0.333333,α置为0.05,效应力...
It performs high-precision statistical power analyses for the most common statistical tests in behavioral research, that is,t tests,F tests, andχ 2 tests. GPOWER computes (1) power values for given sample sizes, effect sizes andα levels (post hoc power analyses); (2) sample sizes for ...
G*Power is a free power analysis program for a variety of statistical tests. We present extensions and improvements of the version introduced by Faul, Erdfelder, Lang, and Buchner (2007) in the domain of correlation and regression analyses. In the new version, we have added procedures to ana...

eter space relevant to your power analysis, one parameter (a, power (1 2 ), effect size, or sample size) can be plotted as a function of another parameter. 1.2.1 Select the statistical test appropriate for your prob- lem In Step 1, the statistical test is chosen using the distribution...
