Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
67 | 80 | 84 | 86 | 92 | 409.0 | 81.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 108.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 54.8
For the lines, you have the data necessary to plot the chart.
