Scatterplot for Perform Gage Linearity And Bias Study

Use Scatterplot to visualize gage linearity and bias study results. With a scatterplot, you can evaluate the accuracy of a single measurement device across its operating range.

This example applies to the Measurement System Analysis Module. For more information, go to www.minitab.com/measurement-system-analysis-module.

Example

In this worksheet, Measurement is the Y variable and contains the observed measurements. Reference is the X variable and contains the reference values for each part.

C1	C2
`Reference`	`Measurement`
1.10	1.15
1.20	1.23
1.30	1.31
1.40	1.41
1.10	1.16
1.20	1.24
1.30	1.32
