Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -13 | -3 | -8 | -25 | -23 | -72.0 | -14.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 12.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -41.4
For the lines, you have the data necessary to plot the chart.
