Power Analysis is used to determine an adequate sample size needed to detect a given effect size for a planned study. It can also be used to determine the power, given an effect size and a sample size.
In this workshop, we will approach power analysis conceptually other than mathematically, then we will provide demonstrations via GPower for t-test (independent samples and paired samples), ANOVA, Repeated-Measures ANOVA, Mixed-Design ANOVA, and Multiple Linear Regression. Finally, we will discuss the difference between prospective power analysis and retrospective power analysis, and why the retrospective power analysis should be avoided.
