The Trebuchet is newer to industry than the Statapult and has a substantial amount of non-linearity in comparison with the Statapult. The Trebuchet is a much more advanced tool and we recommend it as a compliment to the Statapult in any intermediate and advanced levels of training.
The Electromagnet is great for teaching Designed Experiments to people who have an interest in electronics or electro-magnetism. The Electromagnet vividly displays how Design of Experiments can be applied in non-mechanical fields.
The Plop-Fizz Experiment is a great tool to give a student a very fundamental look at Design of Experiments. It demonstrates both linear and quadratic factors, interactions, as well as variance reduction factors.
