Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-54 | -24 | -21 | -22 | -40 | -161.0 | -32.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 9.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -74.2
For the lines, you have the data necessary to plot the chart.
