Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 20 | 20 | 25 | 5 | 14 | 84.0 | 16.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 37.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -4.2
For the lines, you have the data necessary to plot the chart.
