Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -71 | -49 | -49 | -58 | -54 | -281.0 | -56.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -29.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -83.2
For the lines, you have the data necessary to plot the chart.
