Glass refraction measurement data

A process engineer wants to evaluate the glass refractive measurement system for a glass manufacturing process. The engineer asks three operators to measure the refractive properties of 22 glass parts at two stations.

You can use this data to demonstrate Expanded Gage R&R Study.

Worksheet column Description
Part The part identifier
Operator The operator who measured the glass pieces: 1, 2, or 3
Station The measurement station: 1 or 2
Measurement The refractive measurement of each glass piece
