Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 43 | 34 | 42 | 47 | 50 | 216.0 | 43.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 61.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 25.2
For the lines, you have the data necessary to plot the chart.
