Which switch is which? Exploring light switches and circuit breakers with covering arrays

When my wife and I moved into our house, one of my first tasks was to swap the old light switches with new ones in frequently used rooms. Once I figured out how it was done, it seemed simple enough: Go to the circuit box, switch the circuit breaker off […]

During the The Scale-Up of Chemical Processes conference in Brussels earlier this year, the organizers and I decided to do an experiment using JMP. Of course, the experiment had to involve beer tasting! We had 24 participants for the experiment. We used eight Belgian beer brands for testing and planned […]

Why design of experiments keeps the science in science

Teaching with JMP, part 2

After writing the post on Teaching statistics with JMP last month, I didn’t think about a follow-on post since we had so many wonderful comments. But when we heard from Roger Hoerl at Union College about the thesis his student, Keilah Creedon, wrote (using JMP for the designed experiment part), […]
