Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -52 | -50 | -72 | -84 | -85 | -343.0 | -68.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -20.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -116.6
For the lines, you have the data necessary to plot the chart.
