11 Year Old Using Design of Experiments
Posted on March 23, 2011 Comments (2)
This reminds me of great times I had experimenting with my father when I was a kid. Though, to be honest, Sarah is much more impressive than I was.
Here’s Sarah’s whole process: She built the trebuchet, tested it, used JMP for DOE during optimization, changed the hook angle and sling to improve performance, did more tests, entered this new data, reran the model, and made her final prediction graphs. The variables in her DOE were string length, counterweight and projectile weight, and she optimized for distance – that is, how far the projectile would go.
“Rather than doing 125 tests because we have three variables with five levels each, DOE found a way for us to perform only 26 tests and get approximately the same results. I typed in the results, ran the model and used the JMP Profiler. I understood how the variables predicted the outcome and found several patterns,” she explained.
“I hadn’t done any building like that. The whole day was fun. It was a very open learning environment. You were experimenting with things you had never done before. I would definitely do it again,” Sarah said. And she will – next year.
I have collected quite a few design of experiments resources, for those who are interested in learning more. Here is a nice webcast by brother: Combinatorial Testing – The Quadrant of Massive Efficiency Gains, discussing the incredibly efficiency designed combinatorial testing (very similar ideas to design of experiments) can provide.
