Question

1 How many experiment runs are there in a 3 x 4 x 2 factorial design? Runs in 3x4x3x2 factorial design?

2 If 3 variables are studied using 3 levels, how to designate the design and number of experiment runs will it require? and 6 variables at 2 levels?

Answer 1

1 34' x .'s Tortell factors - 3 One with 3 levels oorn with four and one with a levels Total om of experiment svors= 3x442 = 24 ouns b- 3X 4X3 X 2 = 3x4x2 Total Tattors = leti+1)= 4 0 two with 3 levels one centth four and the last one with a levels .: Torel 070, of experiment ruosa 3*4% 2 = 72 ouns ADS (2) - 3 variables with 3 levels Total mo of experienemt ruoss 3 - 27 ovos 6 rawables with 2 levels Total no. of expernend runs aq=64 runs
