December 7, 2017: Dr. Greg Simon Explains Individual, Cluster, and Stepped-Wedge Randomization in a New Prop Video

In a new video in the Living Textbook, Dr. Greg Simon describes the differences between individual, cluster, and stepped-wedge randomization using props, including marbles, Play-Doh, and glassware.

“In the end, it’s all about randomly assigning who gets which treatment, or who gets which treatment when, so that we’re able to make some un-biased judgement about which treatment is really better.” —Greg Simon, MD
