Textile printing data

Fabric appraisers at a textile printing company rate the print quality of cotton fabric on a 1 to 5 point scale. The quality engineer wants to assess the consistency and correctness of the appraisers' ratings. The engineer asks four appraisers to rate print quality on 50 samples of fabric twice, in random order.

You can use this data to demonstrate Attribute Agreement Analysis. Because the data include a known standard for each sample, you can assess the consistency and correctness of ratings compared to the standard as well as compared with other appraisers.
