Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -21 | -16 | -9 | -5 | -9 | -60.0 | -12.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 6.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -30.0
For the lines, you have the data necessary to plot the chart.
