Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 18 | 31 | 30 | 37 | 42 | 158.0 | 31.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 58.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 4.6
For the lines, you have the data necessary to plot the chart.
