Attribute gage data

An engineer uses an attribute gage that compares each part to a set of limits. If the part is within limits, it is accepted. If the part is outside of the limits, the part is rejected. Variable gages indicate how good or bad a part is. But attribute gages only help to determine whether to accept or reject a lot.

To verify the gage for production use, the engineer takes a random sample of 50 parts from the process. Three appraisers assess each part three times.

You can use this data to demonstrate Attribute Gage Study (Analytic Method).
