The
Trebuchet is newer to industry than the Statapult
and has a substantial amount of non-linearity in comparison
with the Statapult. It is a much more advanced tool
and we recommend it as a complement to the Statapult
for 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.
