Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -77 | -79 | -71 | -55 | -62 | -344.0 | -68.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -38.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -98.8
For the lines, you have the data necessary to plot the chart.
