Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-72 | -72 | -74 | -82 | -69 | -369.0 | -73.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -61.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -85.8
For the lines, you have the data necessary to plot the chart.
