Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -14 | -1 | -8 | -6 | 7 | -22.0 | -4.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 16.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -25.4
For the lines, you have the data necessary to plot the chart.
