Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 29 | 27 | 10 | 18 | 25 | 109.0 | 21.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 42.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 0.8
For the lines, you have the data necessary to plot the chart.
