Demo Questions
Question 1
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.
- 10
- 32
- 256
- 64
Correct answer: B
Question 2
If an experiment has 5 factors and no replicates for a 2-level Experimental Design with 16 experimental runs which statement is incorrect?
- The Experimental Design is half-fractional
- The Main Effects are confounded with only 4-way interactions
- The Main Effects for the 5 factors are not aliased or confounded but the 2-way interactions are confounded with the 3-way interactions
- The experiment has 8 experimental runs with the first factor at the high level
Correct answer: C
Question 3
Which statement(s) are correct about the Pareto Chart shown here for the DOE analysis? (Note: There are 2 correct answers).
- It is unknown from this graph how many factors were in the Experimental Design
- The factors to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 2.06
- The effects to keep in the mathematical model are E, D, DE, BD and B with an alpha risk equal to 0.05
- The factors to keep in the mathematical model with a 5% alpha risk are BE, AB, A and AD
Correct answer: AC
Question 4
Fractional Factorial, ____________and Response Surface Method are types of planned experiments.
- Multi-Vari Analysis
- Baldridge Channels
- One Factor at a Time or OFAT
- Factorial Design
Correct answer: D
Question 5
Relative to a Design of Experiments the term ________________ refers to variables being a linear combination of each other.
- Mirror Image
- Directly Parallel
- Collinear
- None of the above
Correct answer: C
Question 6
Which statement(s) are incorrect about Fractional Factorial Designs?
- A Half Fractional Design for 5 factors has the same number of experimental runs as a Full Factorial Design for 4 factors assuming no repeats or replicates or Center Points
- Quarter Fractional experiments can exist for those with 4 factors
- Resolution V design is desired while controlling costs of experimentation
- Half Fractional experiments do not exist for those designs with only 2 factors
Correct answer: C
Question 7
If in an experiment all possible variable pairs sum to zero the design is Orthogonal.
- True
- False
Correct answer: A
Question 8
Which Experimental Design typically is most associated with the fewest number of input variables or factors in the design?
- Fractional Factorial design
- Full Factorial design
- Simple Linear Regression
- Response Surface Design
Correct answer: D
Question 9
The method of Steepest Ascent guides you toward a target inside the original inference space.
- True
- False
Correct answer: B
Question 10
Situations where standardized work needs to be incorporated include all of these except _____________________.
- Machines continually operating to reduce the labor cost per piece
- Lack of a system to assure proper inventory levels at repair stations
- Changeover instructions incomplete
- Process flow for the same product assembly taking various cycle time for completion
Correct answer: A
