Certified Six Sigma Black Belt Exam FREE Certified Six Sigma Black Belt Measurement System Analysis (MSA) Questions and Answers 2 — Questions and Answers
Question 1: In a Gage R&R study, what does 'reproducibility' specifically measure?
- Variation due to different operators measuring the same part (Correct answer)
- Variation due to the measurement instrument itself
- Variation between different parts being measured
- Variation caused by environmental conditions
Correct answer: Variation due to different operators measuring the same part
Reproducibility quantifies the variation in measurements when different operators measure the same part using the same gage.
Question 2: A Gage R&R study shows that the %Study Variation for total Gage R&R is 35%. How should this measurement system be classified?
- Unacceptable and requires improvement (Correct answer)
- Marginally acceptable depending on application
- Acceptable for most applications
- Excellent measurement capability
Correct answer: Unacceptable and requires improvement
A %Study Variation above 30% is generally considered unacceptable, indicating the measurement system contributes too much variation relative to process variation.
Question 3: What is the primary purpose of a linearity study in MSA?
- To determine if measurement bias changes across the operating range of the gage (Correct answer)
- To verify the gage reads correctly at a single reference point
- To assess whether multiple operators get the same results
- To calculate the number of distinct categories the gage can distinguish
Correct answer: To determine if measurement bias changes across the operating range of the gage
A linearity study evaluates whether the bias of a measurement system remains consistent across the full range of expected measurements.
Question 4: What is the minimum number of distinct categories (ndc) recommended by the AIAG for an acceptable measurement system?
- 5 (Correct answer)
- 3
- 7
- 10
Correct answer: 5
The AIAG MSA manual recommends a minimum of 5 distinct categories to confirm the measurement system can adequately distinguish between parts.
Question 5: During an attribute agreement analysis, what does a kappa value of 0.41 to 0.60 indicate?
- Moderate agreement (Correct answer)
- Slight agreement
- Substantial agreement
- Almost perfect agreement
Correct answer: Moderate agreement
A kappa value between 0.41 and 0.60 is interpreted as moderate agreement according to the Landis and Koch benchmark scale.
Question 6: Which MSA technique is most appropriate for evaluating a destructive testing process?
- Nested Gage R&R (Correct answer)
- Crossed Gage R&R
- Standard bias study
- Simple linearity analysis
Correct answer: Nested Gage R&R
A nested Gage R&R design is used when parts are destroyed during testing, so each operator must measure different parts from the same batch rather than the same individual parts.
