Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -47 | -23 | -26 | -27 | -35 | -158.0 | -31.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -4.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -58.6
For the lines, you have the data necessary to plot the chart.
