Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 5 | 21 | 37 | 35 | 43 | 141.0 | 28.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 73.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -16.8
For the lines, you have the data necessary to plot the chart.
