#### Last steps

##### Compute the average

2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
---|---|---|---|---|---|---|

-52 | -33 | -47 | -52 | -58 | -242.0 | -48.4 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-21.4**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-75.4**

##### For the lines, you have the data necessary to plot the chart.
