Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -74 | -74 | -71 | -61 | -73 | -353.0 | -70.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -55.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -85.6
For the lines, you have the data necessary to plot the chart.
