Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 23 | 32 | 30 | 46 | 63 | 194.0 | 38.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 83.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -6.2
For the lines, you have the data necessary to plot the chart.
