Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
28 | 32 | 33 | 35 | 32 | 160.0 | 32.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 38.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 26.0
For the lines, you have the data necessary to plot the chart.
