Question 16

A full factorial experiment is characterized by all of the following properties EXCEPT:

  1. All factors in the experiment are controlled
  2. Higher level interaction effects cannot be estimated
  3. All combinations of the levels of the factors are run in the experiment
  4. The 2-factor, 2-level design is the simplest full factorial experiment

Question 17

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

Question 18

A Black Belt runs an experiment on 2 different shifts comparing two different methods for data entry. The Black Belt wants to learn if there is a difference between methods. She suspects that shifts have impact on the response. However, she is not interested in optimizing the shift. What experimental design technique should the Black Belt use?

  1. Repeats only
  2. Replication and repeats
  3. Run in standard order
  4. Blocking

Question 19

  1. 4
  2. 2
  3. -2
  4. 6

Question 20

Given the image below, what is the main effect of A?

  1. -3
  2. 3
  3. -6
