In the design stages of a research project, it’s important to consider if your sample size is large enough to provide sufficient power (or probability) to detect a hypothesized effect. In this workshop we’ll cover how to calculate power and sample size for various statistical tests using R. We’ll also demonstrate how to use simulation as a way to estimate power for more complicated analyses. Knowledge of basic statistics and familiarity with R would be helpful but are not required.

Our policy is that we do not record live workshops in order to encourage robust Q&A. However, you can always find the full workshop materials for all of our workshops at: https://library.virginia.edu/data/training/past-workshops which allows you to work through the material at your own pace. We also encourage you to reach out to the instructor at any time for a one-on-one consult, and for specific or general questions about any of the topics we cover.
