Question 16

How many experimental runs exist in a Full Factorial and fully randomized design for 4 factors with 2 replicates for the Corner Points and no Center Points? The factors in the experiment are only at 2-levels.

  1. 10
  2. 32
  3. 256
  4. 64

Question 17

If an experiment has 5 factors and no replicates for a 2-level Experimental Design with 16 experimental runs which statement is incorrect?

  1. The Experimental Design is half-fractional
  2. The Main Effects are confounded with only 4-way interactions
  3. The Main Effects for the 5 factors are not aliased or confounded but the 2-way interactions are confounded with the 3-way interactions
  4. The experiment has 8 experimental runs with the first factor at the high level

Question 18

Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note: There are 2 correct answers).

  1. It is unknown from this graph how many factors were in the Experimental Design
  2. The factors to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 2.06
  3. The effects to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 0.05
  4. The factors to keep in the mathematical model with a 5% alpha risk are BE, AB, A and AD
