#### Last steps

##### Compute the average

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

21 | 40 | 38 | 34 | 37 | 170.0 | 34.0 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **55.0**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **13.0**

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

#### Very last step
