Certified Six Sigma Black Belt Exam Certified Six Sigma Black Belt Measurement System Analysis Questions and Answers 2

Question 1

What does a Gage R&R study primarily evaluate in a measurement system?

Accepted Answer

Repeatability and reproducibility of measurements

Answer

A Gage R&R study specifically assesses repeatability (variation from the same operator measuring the same part) and reproducibility (variation between different operators).

Question 2

In an MSA, if the %Study Variation for repeatability is 45%, what is the most appropriate action?

Accepted Answer

Improve or replace the measurement instrument

Answer

High repeatability variation (above 30%) indicates the instrument itself introduces excessive variation and should be improved or replaced.

Question 3

Which type of measurement system error is indicated when measurements consistently read 0.05 units higher than the true reference value?

Accepted Answer

Bias error

Answer

Bias is the systematic difference between the average measured value and the true reference value across the measurement range.

Question 4

What is the minimum number of distinct categories (ndc) recommended by AIAG for an acceptable measurement system?

Accepted Answer

5

Answer

The AIAG MSA manual recommends a minimum of 5 distinct categories to indicate the measurement system can adequately distinguish between parts.

Question 5

During a linearity study, what condition is being assessed?

Accepted Answer

Whether bias remains constant across the full operating range of the gage

Answer

Linearity evaluates whether the measurement bias changes across the expected operating range of the measurement instrument.
