Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -56 | -36 | -24 | -16 | -6 | -138.0 | -27.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 29.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -84.6
For the lines, you have the data necessary to plot the chart.
