WebNov 18, 2024 · Linearity: an absence of bias across a range of values. As the name suggests, Gage R&R studies typically focuses on repeatability and reproducibility. Other characteristics of your measurements system should also be understood and studied as needed. Where Is Gage R&R Used? WebLinearity is a measure of the consistency of Bias over the range of the measurement device. For example, if a bathroom scale is under by 1.0 pound when measuring a 150 pound person, but is off by 5.0 pounds when measuring a 200 pound person, the scale Bias is non-linear in the sense that the degree of Bias changes over the range of use. fiber optic inspection light
