Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 9 | 2 | 8 | 15 | 27 | 61.0 | 12.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 39.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -14.8
For the lines, you have the data necessary to plot the chart.
