What are the advantages of using DOE? Provide three of them. b) If you have data for an independent variable and a dependent variable but base on your initial data the independent variable doesn't seem to have an effect although you are expecting that the opposite conclusion. What would you do to see if your own conclusion maybe statistically acceptable? 2. (1 point) An experiment with 3 factors and 3 levels each factor. What is the total number of possible factors-levels combinations for a full factorial design? 3. (1 point) What is confounding (aliasing)? 4. (1 point) What is the biggest flaw of one-factor-at-a-time design of experiment? 5. (1 point) If you have a study with 4 continuous factors, two level each and 1 response variable. Suppose you are interested in finding out which factor(s) and 2-factor interactions have significant effect(s) on your result. How would use DOE in JMP and perform fractional factorial design since performing a full factorial design may not be approved for your experiments? Show a screenshots of your design list as well as your final table DOE.
