The attribute studies are used where, instead of a measurement device, operators or appraisers make a judgment on the acceptability of items. The study here is used to assess the appraisers' ability to agree with themselves and the standards in a study.

For this recipe, we will use data for an inspection on car bumpers. The appraisers inspect the bumpers to check for a color match with the vehicle they are to be fitted to.

A total of 30 samples are tested by three appraisers with two replicates. A standard was identified for the results in the study, and this is given in the sixth column. We will use the attribute study to compare the ability of appraisers to agree with their own results and to the standards.

Here, we will use the Assistant menu to run the attribute studies; a similar study can be run from the Stat menu and Quality Tools.
