Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -24 | -1 | 4 | 16 | 17 | 12.0 | 2.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 50.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -45.6
For the lines, you have the data necessary to plot the chart.
