a.) fractional factorial
b.) full factorial
c.) one factor at a time
d.) one level at a time.
24. The main effect of factor A, two level experiment, is found by computing the average response when factor A is high and then computing the average response when factor A is low. Finally, the difference between the two is calculated.
