Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -50 | -56 | -60 | -63 | -79 | -308.0 | -61.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -31.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -91.6
For the lines, you have the data necessary to plot the chart.
