Variability Gauge Charts
Evaluate a Continuous Measurement Process Using Gauge R&R
Variability gauge charts analyze continuous measurements and can reveal how your measurement system is performing. You can also perform a gauge study to see measures of variation in your data.
Tip: This chapter covers only variability charts. For more information about attribute charts, see Attribute Gauge Charts.
