Youden Plot Template in Excel
Labs use the Youden Plot to compare two runs within the same lab and/or two runs between labs.
Here is an example of the Youden Plot template in the QI Macros SPC Software.
How to Create a Youden Plot:
- Input the Lab id in column A. These entries will be plotted on the chart so keep them short.
- Input data from Run 1 in column B.
- Input data from Run 2 in column C.
How to Interpret a Youden Plot
The above Youden Plot shows that lab 4 is biased low. Lab 3 had inconsistency between run 1 and run 2.
