I explain the concept of effect modification (also commonly referred to as interaction...although the two different slightly). The focus is on building an understanding of what it means, and the criteria for identifying.

In videos that follow I provide a few examples of effect modification, both conceptually as well as looking at in in data in R.

These videos support a course I teach at The University of British Columbia (SPPH 500), which covers the use of regression models in Health Research. These videos were put together to use for remote teaching in response to COVID.
