TS Measurement Systems Analysis (MSA) 2

Question 1

In a standard AIAG crossed GR&R study, how many parts, appraisers, and trials are most commonly recommended?

Accepted Answer

10 parts, 3 appraisers, 2 trials

Answer

5 parts, 2 appraisers, 3 trials

Answer

10 parts, 2 appraisers, 5 trials

Answer

5 parts, 3 appraisers, 5 trials

Question 2

What does the 'Number of Distinct Categories' (NDC) indicate in an MSA study?

Accepted Answer

The number of non-overlapping data groups the measurement system can reliably distinguish

Answer

The number of operators required to complete the study

Answer

The number of different measurement tools tested during the study

Answer

The number of parts that failed measurement system requirements

Question 3

Which advantage does the ANOVA method offer over the range method in a GR&R study?

Accepted Answer

It can separate and quantify the part-by-operator interaction effect

Answer

It requires fewer parts and operators to complete

Answer

It eliminates the need for a reference standard

Answer

It produces a lower %GRR result by default

Question 4

What does the %P/T ratio measure in measurement systems analysis?

Accepted Answer

The ratio of gauge variation to the product tolerance (specification range)

Answer

The percentage of parts that pass tolerance inspection

Answer

The proportion of total variation explained by the process

Answer

The percentage of trials completed within the calibration interval

Question 5

'Stability' in measurement systems analysis refers to:

Accepted Answer

The change in bias of a measurement system over time

Answer

The ability of a gauge to produce zero variation between consecutive readings

Answer

The consistency of measurements within a single short measurement session

Answer

The maximum allowable difference between two operators' readings

Question 6

In an attribute MSA study, a Type I error (false alarm) occurs when:

Accepted Answer

A conforming part is incorrectly classified as nonconforming

Answer

A nonconforming part is incorrectly classified as conforming

Answer

An operator measures a part outside the tolerance range

Answer

The gauge fails to measure parts at the extreme ends of its range

Question 7

What is the primary purpose of conducting 'blind' measurements in an MSA study?

Accepted Answer

To ensure appraisers measure parts without knowledge of previous readings or part identity, reducing bias

Answer

To prevent appraisers from knowing the gauge's calibration status

Answer

To hide measurement results from production supervisors during the study

Answer

To test the gauge under low-light or adverse operating conditions
