Join us for a laptop-optional workshop to learn more about statistical power, the relationship of statistical power to study design, and how to design a simulation study to assess power. Code samples will be provided in both R and Python.

In this workshop, you will learn how to:

Workshop outline:

1. Welcome and introduction
    a. Define statistical power in the context of null hypothesis significance testing

2. Overview of power calculations
    a. Why calculate power?
    b. What impacts power?
    c. Why is power meaningful?

3. Introduction to simulation studies for power
    a. Precision
    b. Two-group comparison
    c. Three-group comparison
    d. Correlation

4. Conclusions/next steps
    a. Detecting and avoiding common mistakes

Prerequisites

You should be able to do these things in either R or Python:
