Lean Six Sigma Green Belt Certification Measurement System Analysis and Gage R&R 2

Question 1

Reproducibility in Gage R&R is best described as:

Accepted Answer

Variation caused by different operators measuring the same parts with the same gage

Answer

Variation from the same operator measuring the same part repeatedly

Answer

Variation caused by using gages from different manufacturers

Answer

Variation due to changing environmental conditions

Question 2

Linearity in the context of measurement system analysis means:

Accepted Answer

The bias of the measurement system is consistent across its full operating range

Answer

The measurement system produces the same result each time it is used

Answer

Different operators obtain the same measurement results

Answer

The gage has been calibrated against a certified standard

Question 3

What is the standard AIAG Gage R&R study design in terms of parts, operators, and replicates?

Accepted Answer

10 parts, 3 operators, 2 replicates

Answer

5 parts, 2 operators, 2 replicates

Answer

20 parts, 5 operators, 3 replicates

Answer

10 parts, 5 operators, 1 replicate

Question 4

Which type of Gage R&R study design is used when parts are destroyed or consumed during measurement?

Accepted Answer

Nested Gage R&R

Answer

Crossed Gage R&R

Answer

Attribute Gage R&R

Answer

Expanded Gage R&R

Question 5

Stability (drift) in a measurement system refers to:

Accepted Answer

The change in the measurement system's bias over time when measuring the same reference part

Answer

The ability of a gage to consistently measure parts across multiple operators

Answer

The smallest increment the gage can reliably detect

Answer

The consistency of measurements taken at different locations in a facility

Question 6

What does the %Tolerance method in Gage R&R analysis compare?

Accepted Answer

Measurement system variation as a percentage of the engineering specification tolerance

Answer

Operator skill variation as a percentage of total variation

Answer

Part-to-part variation as a percentage of total observed variation

Answer

Gage bias as a percentage of the measurement range
