|---|---|---|---|---|---|---|
| -14 | -8 | -2 | -6 | 0 | -30.0 | -6.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 7.5
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -22.5
For the lines, you have the data necessary to plot the chart.
