Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 31 | 23 | 14 | 28 | 36 | 132.0 | 26.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 50.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 2.4
For the lines, you have the data necessary to plot the chart.
