Question 66

A measurement system is said to have a consistent bias if:

  1. The standard deviation of the system is consistent across the measurement range
  2. The difference between the average reading of the measurement tool and reference value is the same across the operating range of the tool operation
  3. The standard deviations of the reading given by the measurement tool when measuring a standard is the same across the operating range of the tool operation
  4. All tools of the same type give the same variance reading

Question 67

The variance of your measurement system is 25. The total standard deviation is 50. What is your % R & R?

  1. 15%
  2. 50%
  3. 10%
  4. 22%

Question 68

What type of knowledge is gained by doing an MSA?

  1. Determine the size of the measurement variability
  2. Determine if the measurement system is stable over time
  3. Determine if the measurement system is capable of making the required measurements
  4. All of the above

Question 69

A measurement system has sufficient discrimination if:

  1. A measurement system should not discriminate
  2. The measurement unit is at most one-tenth of the six sigma spread of the total process variation
  3. You can get output to the second decimal point
  4. If the tool can be easily calibrated

Question 70

  1. Repeatability
  2. Reproducibility
  3. Repeatability and reproducibility
  4. Improve variation of process being measured
