|---|---|---|---|---|---|---|
| 29 | 46 | 45 | 50 | 60 | 230.0 | 46.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 79.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 13.0
For the lines, you have the data necessary to plot the chart.
