Flour weight data

A process engineer wants to analyze the weighing system of a flour milling process. The engineer selects three samples that represent the expected range of the process variation. Three operators weigh the three samples, three times per sample, in a random order.

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