Sample Size and Power Calculations

Stats Central, UNSW: Course Overview

Power calculations and sample size determination are essential parts of planning a scientific study. In this online course (run over two half-days), we will introduce the basic principles of precision-based and power-based sample size calculations. Using practical examples, we will demonstrate how to perform sample size calculations for common designs in single-sample studies and for comparing groups, as well as discussing practical issues such as multiple comparisons. No knowledge of statistical software will be required.
