Power & Sample Size Workshop

Wednesday, December 9, 2020 10:00am to 1:00pm

Add to calendar

In this workshop, we will provide a brief review of the concepts underlying power and sample size analysis. Following this, we will use R for hands-on programming practice with power and sample size calculations for several different types of analyses, including parametric and nonparametric tests using both analytical and simulation approaches.

Learning Objectives

  • Become familiar with concepts such as type I and II error, effect sizes, and confidence intervals

  • Know how to do power and sample size calculations for several common study designs and tests

  • Know how to use simulations for more complex analyses

  • Know how to create power and sample size plots from grid searches

Prerequisites

A basic understanding of statistics and the purpose of doing power and sample size calculations, and familiarity with R programming will be helpful but not required.

Software

If you want to follow the R coding exercises presented during this workshop, please install R and RStudio beforehand.
