|---|---|---|---|---|---|---|
| 5 | 22 | 20 | 18 | 28 | 93.0 | 18.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 42.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -5.4
For the lines, you have the data necessary to plot the chart.
