Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -46 | -21 | -20 | -15 | -14 | -116.0 | -23.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 15.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -62.2
For the lines, you have the data necessary to plot the chart.
