Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 5 | 12 | 7 | 11 | 31 | 66.0 | 13.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 43.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -16.8
For the lines, you have the data necessary to plot the chart.
