Description

This webinar will introduce the concepts and jargon of power and sample size calculations, such as alpha levels, power, and minimum detectable effect sizes. We will do several basic calculations manually and then demonstrate how to replicate these calculations using Stata's power commands. Next we will demonstrate how to create tables and graphs for power, sample size, and minimum detectable effect sizes for a range of values. We will conclude with a discussion of strategies to increase statistical power.
