Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -42 | -39 | -36 | -36 | -23 | -176.0 | -35.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -14.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -56.2
For the lines, you have the data necessary to plot the chart.
