#### Last steps

##### Compute the average

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

-63 | -60 | -68 | -65 | -57 | -313.0 | -62.6 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-50.6**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-74.6**

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