Last steps
Compute the average
| 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|
| -103 | -143 | -107 | -89 | -442.0 | -110.5 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -41.5
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -179.5
For the lines, you have the data necessary to plot the chart.
