Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -52 | -43 | -42 | -54 | -54 | -245.0 | -49.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -31.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -67.0
For the lines, you have the data necessary to plot the chart.
