Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
2 | 15 | 9 | 4 | 13 | 43.0 | 8.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 23.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -6.4
For the lines, you have the data necessary to plot the chart.
