Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -7 | -1 | 0 | -6 | 0 | -14.0 | -2.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 4.333333333333333333
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -13.666666666666666667
For the lines, you have the data necessary to plot the chart.
