---|---|---|---|---|---|---|
-91 | -120 | -110 | -121 | -95 | -537.0 | -107.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -68.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -146.4
For the lines, you have the data necessary to plot the chart.
