Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-30 | -29 | -16 | -21 | 8 | -88.0 | -17.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 27.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -62.6
For the lines, you have the data necessary to plot the chart.
