IBM® SPSS® Statisticsprovides the following Power Analysis procedures: One Sample T-Test In one-sample analysis, the observed data are collected as a single random sample. It is assumed that the sample data independently and identically follow a normal distribution with a fixed mean and varia...
功效分析(Power analysis)不仅能帮助我们在实验前确定合适的样本量,还能帮助我们更准确地解释实验结果。 一、假设检验 要理解功效,首先要对统计学的假设检验(原假设、备择假设)以及假设检验的两类错误(I类错误α、II类错误β)有一定的了解,下面进行简单介绍。 1、原假设与备择假设 在假设检验中,原假设(H0)与备...

In this article, the authors clarify these 2 types of power analysis and discuss functionalities of 8 programs/packages (G*Power 3.1.3, PASS 11, SAS/STAT 9.3, Stata 12, SPSS 19, SPSS/Sample Power 3.0.1, Optimal Design Software 2.01, and MLPowSim 1.0 BETA) to encourage proper and ...
In my opinion, SPSS power analysis is a pathetic attempt to compete with G*Power. If you don't believe me, just try running a couple of power analyses in both programs simultaneously. If you do believe me, ignore SPSS power analysis and just go for G*Power.Thanks...
