ABSTRACT
Measurement system analysis (MSA) is used to statistically evaluate a measurement system. An MSA assesses the accuracy of measurements; this is the difference between observed measurement results and the true value as well as the stability, which is the difference between measurements taken with the same measuring device at different times. Accuracy is sometimes also referred to as bias. It also assesses the resolution and linearity of measuring devices. Resolution is the capability to detect the smallest acceptable changes and linearity is the difference in accuracy throughout different areas in a measuring devices operating range. Precision is also assessed; this is the closeness of values when a measurement is repeated (Chrysler et al. 2010).
