#### Last steps

##### Compute the average

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

-4 | 9 | 11 | -5 | 1 | 12.0 | 2.4 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **23.4**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-18.6**

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

#### Very last step

##### The percent of students getting a Free or Reduced Price Meal comes from the following sources:
