Power calculations and sample size determination are essential parts of planning a scientific study. In this one-day course we will introduce the basic principles of precision-based and power-based sample size calculations. We will demonstrate how to perform sample size calculations for various outcome types in single-sample studies and for comparing groups, as well as discussing related issues such as multiple comparisons. This course will highlight some useful R packages and provide the tools for running basic simulations in R.
