Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -8 | -2 | 9 | 8 | 7 | 14.0 | 2.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 23.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -18.2
For the lines, you have the data necessary to plot the chart.
