Linearity and Bias Folio
The linearity and bias folio is used to estimate the accuracy of a measuring device, or gage. Accuracy is defined in terms of bias and linearity.
- Bias is the difference between the "true" value of a measured part and the observed average. For example, if the reading of a scale is always much higher than the actual weight of the measured object, then the scale has a bias issue.
- Linearity is the relationship between a gage's bias and the "true" value of the measured part. For example, if the bias of a scale increases rapidly as the weight of the measured object increases, then the scale has a linearity issue.
To add a linearity and bias folio to your project, choose Home > Insert > Linearity and Bias, or right-click the Test and Planning folder on the current project explorer and choose Add Measurement Systems Analysis > Linearity and Bias on the shortcut menu.
