Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -56 | -53 | -54 | -51 | -70 | -284.0 | -56.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -35.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -77.8
For the lines, you have the data necessary to plot the chart.
