CQE Inspection and Testing Methods 3

Question 1

In a gage R&R study, 'repeatability' measures variation due to:

Accepted Answer

The same operator measuring the same part multiple times with the same gage

Answer

Different operators using the same gage

Answer

Part-to-part variation in the sample

Answer

Environmental conditions during measurement

Question 2

A process produces parts with a true mean of 50.1 mm against a target of 50.0 mm. The inspector's gauge consistently reads 50.3 mm. What type of measurement error is present?

Accepted Answer

Bias (accuracy error)

Answer

Repeatability error

Answer

Linearity error

Answer

Stability error

Question 3

What is the purpose of a receiving inspection skip-lot program?

Accepted Answer

To reduce inspection frequency for suppliers with proven quality history while maintaining quality protection

Answer

To eliminate all receiving inspection costs

Answer

To skip inspection for rush orders only

Answer

To transfer inspection responsibility entirely to the supplier

Question 4

In dimensional measurement, what does 'measurement uncertainty' represent?

Accepted Answer

The range within which the true value is expected to lie with a stated confidence level

Answer

The probability of operator error

Answer

The calibration due date tolerance

Answer

The measurement equipment's age factor

Question 5

Which inspection sampling approach is used when the cost of inspection is very high but the cost of passing a defective is also very high?

Accepted Answer

100% inspection (complete inspection)

Answer

Reduced inspection

Answer

Skip-lot sampling

Answer

Single sampling with a large AQL

Question 6

What is the purpose of attribute agreement analysis (AAA) in measurement system analysis?

Accepted Answer

To evaluate the consistency of operators making pass/fail decisions on the same parts

Answer

To calibrate go/no-go gauges against standards

Answer

To determine the correct AQL for attribute inspection

Answer

To calculate the sample size for attribute control charts
