|---|---|---|---|---|---|---|
| -3 | 2 | 4 | 4 | 17 | 24.0 | 4.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 25.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -16.2
For the lines, you have the data necessary to plot the chart.
