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.
Because the data include a known standard for each sample, the quality engineer can assess the consistency and correctness of ratings compared to the standard as well as compared to other appraisers.
The p-value of 0.0000 in the output is rounded. But you can safely conclude that the p-value is very low and is < 0.00005.
