|---|---|---|---|---|---|---|
| 9 | 31 | 26 | 28 | 25 | 119.0 | 23.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 47.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -0.2
For the lines, you have the data necessary to plot the chart.
