Figure 8.7 Average and Range Charts
Looking at the Average Chart, you can see that the variability in the part measurements is outside of the
control limits. This is desirable, indicating measurable part to part variation.
Looking at the Range Chart, you can see that the variability is not outside of the control limits. This is
desirable, indicating that the operators are measuring the same way and have similar variation.
Examine Interactions
Take a closer look for interactions between operators and parts. From the red triangle menu next to
Measurement Systems Analysis, select Parallelism Plots.
