Strategy 2
The wheat flour amount is fixed at 3940g, but that of the active ingredients is varied from 30 to 60 g with the ratio of A : B : C fixed at 3:2:1. The combinations to be tested are listed in the Table .
It is a single-factor experiment with four test levels of baking powder. Actually only the ratio of chemicals to flour are changed in the study. In this way the effect of changing the chemicals: flour ratio or of changing the amount of chemicals while holding the amount of flour constant can be measured. In this experimental design the effect of ratio of the chemicals to flour would be examined. Note that if the percentages of A, B and C are varied in addition as in the first experiment, this would then constitute a flour-component, mixture-amount experiment.
