Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
9 | 29 | 42 | 42 | 42 | 164.0 | 32.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 74.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -9.2
For the lines, you have the data necessary to plot the chart.
