Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
49 | 48 | 61 | 62 | 73 | 293.0 | 58.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 88.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 28.6
For the lines, you have the data necessary to plot the chart.
