If you followed Taguchi’s principles, and you wanted to investigate a design with 5 factors at 2 levels, how many experiments do you need? How many would you need if you used 5 factors at 2 levels in Classical Statistics with full factorial experiments; half factorial as well as Saturated ? Some of the students can try their own numbers such as 3 factors at 2 levels; 2 factors at 2 levels; 2 factors at 3 levels, 3 factors at 3 levels, etc… I would like each student to have a unique set of factors and levels so I can be sure that everyone understands the Taguchi principles in DoE.
