Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 32 | 35 | 41 | 53 | 53 | 214.0 | 42.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 69.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 15.8
For the lines, you have the data necessary to plot the chart.
