Teaching Split Plot Experiments With a Boomerang Tin

Abstract

This article presents an example on how to teach split-plot experimental designs based on a hands-on exercise. This is a toy called boomerang tin which utilizes a rubber band to store and release energy. The set up and mechanisms of the hands-on example are explained followed by a description of how it can be leveraged in teaching split plot DoE. An actual design is set up, analyzed and discussed to provide reference for its usage in class.
