Question 21

A Black Belt is in the early stages of a problem solving effort. The Black Belt determines that the data gathered so far requires a DOE to gain additional insight and to understand which factors are important. There are 8 factors and budget is limited. What type of experiment is most appropriate?

  1. Full factorial
  2. Fractional factorial
  3. Response surface methodology
  4. One factor at a time

Question 22

Following is a confounding pattern of a DOE: A =BCD - B =ACD - C =ABD - D =ABC - AB=CD - AC=BD - AD = BC - Based on this structure, what is the resolution of the design:

  1. III
  2. IV
  3. V
  4. None, it is a full factorial

Question 23

In a sequential experimentation strategy, RSM experiments are most likely to be conducted at which of the following phases?

  1. As a follow-up experiment to earlier experiments to help find optimum settings or if curvature was detected
  2. In the initial conjecture phase
  3. After making confirmation runs, especially if an acceptable linear model with high R-squared has been obtained
  4. As a first experiment before spending 25% of resources

Question 24

Which of the following best completes this statement? Factors are ___________ and responses are ____________.

  1. Input variables, output variables
  2. Output variables, input variables
  3. Outputs, inputs
  4. A and C only

Question 25

A Black Belt has run a full factorial experiment. The below image illustrates an interaction plot from the analysis. What level of interaction is there between these two factors?

  1. No interaction
  2. Strong interaction
  3. Weak interaction
  4. Three-way interaction
