Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 77 | 85 | 82 | 93 | 87 | 424.0 | 84.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 99.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 69.8
For the lines, you have the data necessary to plot the chart.
