Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-67 | -57 | -65 | -54 | -58 | -301.0 | -60.2 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -45.2
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -75.2
For the lines, you have the data necessary to plot the chart.
