Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-62 | -60 | -52 | -26 | -17 | -217.0 | -43.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 16.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -103.4
For the lines, you have the data necessary to plot the chart.
