# Teaching Split Plot Experiments With a Boomerang Tin

## TL;DR

This paper demonstrates a hands-on teaching method for split-plot experimental designs using a toy called boomerang tin, illustrating setup, analysis, and classroom application.

## Contribution

It introduces a practical, toy-based exercise to effectively teach split-plot designs in experimental education.

## Key findings

- Effective in illustrating split-plot concepts
- Provides a reproducible classroom example
- Enhances student understanding of experimental design

## 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.
