Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 9 | 9 | 24 | 34 | 29 | 105.0 | 21.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 54.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -12.0
For the lines, you have the data necessary to plot the chart.
