Last steps
Compute the average
| 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|
| -33 | -39 | -33 | -33 | -138.0 | -34.5 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -25.5
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -43.5
For the lines, you have the data necessary to plot the chart.
