Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 78 | 91 | 85 | 90 | 97 | 441.0 | 88.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 109.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 67.2
For the lines, you have the data necessary to plot the chart.
