Why use factorial plots? Answer: e.


Option 1: Allows you to see the plots of the main effects
Option 2: Allows you to see the interaction plots
Option 3: Allows you to see the cube plots
Option 4: Shows how to set each factor to either maximize or minimize the response
Option 5: All of the above


What tools can be used to determine if factors have interaction?


Option 1: Balanced ANOVA
Option 2: Standardized effects
Option 3: Interaction plots
Option 4: Fractional factorial fits
Option 5: All of the above


What does it mean when no p-values are presented in the ANOVA output?


Option 1: Means the factors are statistically significant
Option 2: Means the factors are not different
Option 3: Only one repetition was run at each treatment combination.
Option 4: Had no center points
Option 5: All of the above


Why do we replicate our experimental runs?


Option 1: So we can look for special causes
Option 2: To obtain a better estimate of the error and look at interactions
Option 3: To determine the factor levels
Option 4: So we can look at the same thing run again
Option 5:

Option 2: False
Option 3:
Option 4:
Option 5:


Why use center points in your experimental design?

Option 1: True
Option 2: False
Option 3:
Option 4:
Option 5:


Fractional factorial designs require more runs than full factorial designs given the same number of factors.


Option 1: True
Option 2: False
Option 3:
Option 4:
Option 5:


What is the main reason for using a fractional factorial design?


Option 1: True
