Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
1 | 19 | 5 | 16 | 35 | 76.0 | 15.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 54.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -23.8
For the lines, you have the data necessary to plot the chart.
