Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-57 | -56 | -57 | -46 | -42 | -258.0 | -51.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -30.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -72.6
For the lines, you have the data necessary to plot the chart.
