Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -42 | -24 | 0 | -6 | -2 | -74.0 | -14.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 35.5
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -72.5
For the lines, you have the data necessary to plot the chart.
