Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -67 | -67 | -61 | -57 | -58 | -310.0 | -62.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -50.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -74.0
For the lines, you have the data necessary to plot the chart.
