G*Power(ErdFelder，Faul，&Buchner，1996)被设计为一个通用的独立功率分析程序，用于社会和行为研究中常用的统计测试。G*Power 3是对以前版本的主要扩展和改进。它在广泛使用的计算机平台(即Windows XP、Windows Vista和Mac OS X 10.4)上运行，并涵盖t、F和chi(2)测试族的许多不同的统计测试。此外，它还包括z测试和一些精确测试的功率分析。G*Power 3提供改进的效果尺寸计算器和图形选项，支持基于分布和基于设计的输入模式，并提供用户可能感兴趣的所有类型的功率分析。像它的前身一样，G*Power 3是免费的。
G*Power (Erdfelder, Faul, & Buchner, 1996) was designed as a general stand-alone power analysis program for statistical tests commonly used in social and behavioral research. G*Power 3 is a major extension of, and improvement over, the previous versions. It runs on widely used computer platforms (i.e., Windows XP, Windows Vista, and Mac OS X 10.4) and covers many different statistical tests of the t, F, and chi(2) test families. In addition, it includes power analyses for z tests and some exact tests. G*Power 3 provides improved effect size calculators and graphic options, supports both distribution-based and design-based input modes, and offers all types of power analyses in which users might be interested. Like its predecessors, G*Power 3 is free.
