Demo Questions

Question 1
Which statement(s) are correct about the Regression shown here? (Note: There are 2 correct answers).
  1. The dependent variable is the outside temperature
  2. The relationship between outside temperature and number of customers per hour is a Linear Regression
  3. The dashed lines indicate with 95% confidence where all of the process data should fall between
  4. The dashed lines indicate with 95% confidence the estimate for the Quadratic Regression Line
  5. The predicted number of customers per hour is close to 5 if the outside temperature is 10 deg C
Correct answer: DE
Question 2
Which statement(s) are correct about the Factorial Plot shown here? (Note: There are 3 correct answers).
  1. When the cutting speed increased from low to high level, the tool age increases
  2. The coefficient of the metal hardness is positively related to the output of tool age
  3. The coded coefficient is lower for cutting speed than the cutting angle related to the output of tool age
  4. These plots prove a statistically significance factor with 95% confidence
  5. These plots are an example of interaction plots
Correct answer: ABC
Question 3
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
Correct answer: B
Question 4
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
Correct answer: C
Question 5
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
Correct answer: AC
Question 6
Fractional Factorial, ____________and Response Surface Method are types of planned experiments.
  1. Multi-Vari Analysis
  2. Baldridge Channels
  3. One Factor at a Time or OFAT
  4. Factorial Design
Correct answer: D
Question 7
Relative to a Design of Experiments the term ________________ refers to variables being a linear combination of each other.
  1. Mirror Image
  2. Directly Parallel
  3. Collinear
  4. None of the above
Correct answer: C
Question 8
Which statement(s) are incorrect about Fractional Factorial Designs?
  1. 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
  2. Quarter Fractional experiments can exist for those with 4 factors
  3. Resolution V design is desired while controlling costs of experimentation
  4. Half Fractional experiments do not exist for those designs with only 2 factors
Correct answer: C
Question 9
If in an experiment all possible variable pairs sum to zero the design is Orthogonal.
  1. True
  2. False
Correct answer: A
Question 10
Review the analysis shown here. Which statements are true about the process? (Note: There are 3 correct answers).
  1. The initial focus for this project would be to determine why the thicknesses are so frequently too low
  2. The majority of the process is closer to the lower specification limit
  3. This process is described with the Weibull Distribution
  4. The process has more problems with Variation than Centering
  5. The process follows a non-normal distribution with the given data
Correct answer: BDE
