Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -108 | -110 | -102 | -101 | -92 | -513.0 | -102.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -81.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -123.6
For the lines, you have the data necessary to plot the chart.
