Linearity

Answer

Stability

Answer

Reproducibility

Question 6

What does 'linearity' describe in the context of a measurement system?

Accepted Answer

The change in bias across the operating range of the measurement instrument

Answer

The consistency of measurements taken in a straight-line pattern across the shop floor

Answer

The correlation between two different measurement instruments

Answer

The ability of the gauge to measure parts in a linear sequence

Question 7

In MSA, 'stability' (or 'drift') refers to which measurement system property?

Accepted Answer

Answer

The consistency of measurements across different locations

Answer

The operator's ability to hold the gauge steady
