#### Last steps

##### Compute the average

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

-43 | -36 | -33 | -36 | -36 | -184.0 | -36.8 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-27.8**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-45.8**

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