Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -32 | -30 | -25 | -22 | -13 | -122.0 | -24.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -3.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -45.4
For the lines, you have the data necessary to plot the chart.
