Last steps
Compute the average
2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|
-69 | -62 | -68 | -62 | -51 | -312.0 | -62.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -41.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -83.4
For the lines, you have the data necessary to plot the chart.
