Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -14 | 4 | 14 | 11 | 11 | 26.0 | 5.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 38.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -27.8
For the lines, you have the data necessary to plot the chart.
