Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 0 | 7 | 20 | 17 | 46 | 90.0 | 18.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 70.5
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -25.5
For the lines, you have the data necessary to plot the chart.
