Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-35 | -35 | -26 | -12 | -17 | -125.0 | -25.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 5.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -55.0
For the lines, you have the data necessary to plot the chart.
