Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -26 | -11 | 0 | 1 | -7 | -43.0 | -8.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 22.25
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -43.75
For the lines, you have the data necessary to plot the chart.
