Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 0 | -11 | 1 | 3 | -7.0 | -1.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 18.666666666666666667
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -23.333333333333333333
