Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -14 | -9 | -8 | -5 | -4 | -40.0 | -8.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 1.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -17.0
For the lines, you have the data necessary to plot the chart.
