#### Last steps

##### Compute the average

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

-56 | -53 | -54 | -51 | -70 | -284.0 | -56.8 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-35.8**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-77.8**

##### 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:

2015 | 2016 | 2017 | 2018 | 2019 | |

• Any result above zero is proficient; below is not proficient. • There is a 99% chance that results will remain the same in coming years, which is to say, between the Upper and Lower Control Limits (the gray lines). • The houses with the % of students receiving a Free or Reduced Price Meal is a measure of wealth/poverty.
