|---|---|---|---|---|---|---|
| 0 | 9 | 14 | 9 | 16 | 48.0 | 9.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 21.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 3.0
For the lines, you have the data necessary to plot the chart.
