Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-18 | -3 | 8 | 14 | 27 | 28.0 | 5.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 56.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -45.4
For the lines, you have the data necessary to plot the chart.
