#### Last steps

##### Compute the average

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

-20 | -2 | 1 | -7 | -21 | -49.0 | -9.8 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **20.2**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-39.8**

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