Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 83 | 85 | 82 | 79 | 78 | 407.0 | 81.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 87.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 75.4
For the lines, you have the data necessary to plot the chart.
