Uses of Factorial design

Answer – The factorial design can be used:

1. Identify which factors have the most important effect on the reaction.
2. Decide whether further investigation of the effect of a factor is appropriate or not.
3. Check the functional dependency of the reaction on multiple factors simultaneously (if and only if you examine many levels of each factor).
4. Determine whether the specified factors affect the response of a given treatment.
5. See if two factors interact with each other.
6. Optimize the response in screening experiments.
7. Reduce the possibility of missing an effect as the selected material is insensitive.
