Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 90 | 99 | 104 | 100 | 101 | 494.0 | 98.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 113.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 83.8
For the lines, you have the data necessary to plot the chart.
