3. Types of DOE and sample size calculation ?

Question

Accepted Answer

DOE types include screening, factorial, response surface, and mixture designs. Sample size calculation depends on the type of DOE.

Screening designs are used to identify the most important factors affecting a response.
Factorial designs are used to study the effects of multiple factors and their interactions.
Response surface designs are used to optimize a response by finding the best combination of factors.
Mixture designs are used when the factors are proportions of different components.
Sample size calculation depends on the type of DOE and the desired power and significance level.
For example, a screening design may require a smaller sample size than a response surface design.
Software such as Minitab or JMP can be used to calculate sample size for different types of DOE.
