Gage R&R is the type of Measurement System Analysis (MSA) that is used to quantify how well a variable (continuous) measurement system is working
Resolution (or Discrimination) is the smallest division on the scale of the gauge or the smallest difference in reading that can be shown on the display of a measuring instrument. The higher the resolution, the smaller the measurement it can record
Bias (or Accuracy) is the difference between the average of observed values and the standard (actual value)
Linearity is the consistency of the gauge across its entire range
Stability is consistency in the gauge over a period of time. Stability is observed if observed values are same when the same operator measures the same unit with the same measuring equipment over an extended period of time
Precision is the variation observed between repeated observations of the same unit – either due to operator (Reproducibility) or due to equipment (Repeatability)
