If you specify a reference value for each part, Minitab displays the Appraiser vs Standard graph.
The Appraiser vs Standard graph shows the correctness of each appraiser's ratings. The graph contains the following components for each appraiser:
- Blue circle: The actual percentage matched.
- Red line: The 95.0% confidence interval for percentage matched.
- Blue Xs: The lower and upper limits for the 95.0% confidence interval.
This interval plot indicates that Amanda has the most correct ratings and Eric has the least correct ratings.
