Question

An estimate of the measurement error is obtained through an index is known as:

• A. Precision-to-tolerance Ratio
• B. Tolerance-to-precision Ratio
• C. Capability Ratio
• D. Taguchi Capability Ratio

Hint:

In quality control, it is important to minimize measurement error. The Precision-to-tolerance ratio is a useful tool for assessing whether your measurement system is sufficiently precise for your specifications.

Answer 1

The Correct Option is A

The Precision-to-tolerance Ratio is used to estimate the measurement error in relation to the tolerance. It compares the precision of a measurement system (the consistency of the measurements) to the allowable tolerance (the acceptable range of measurements). A smaller ratio indicates better precision in measurement, making it a key factor in quality control and process improvement. The other options refer to related but different concepts: - Tolerance-to-precision ratio is not typically used for error estimation. - Capability ratio refers to the ability of a process to meet specification limits. - Taguchi capability ratio is used in the Taguchi method for quality improvement, but it is not specifically used to estimate measurement error.
