Last steps
Compute the average
| 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|
| 46 | 58 | 70 | 174.0 | 58.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 94.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 22.0
For the lines, you have the data necessary to plot the chart.
