Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -80 | -87 | -97 | -97 | -86 | -447.0 | -89.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -68.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -110.4
For the lines, you have the data necessary to plot the chart.
