#### Last steps

##### Compute the average

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

9 | 23 | 32 | 27 | 38 | 129.0 | 25.8 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **55.8**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-4.2**

##### 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:

Zero+ meets standard.

**8% less $meal**

**9% less $meal**

**11% less $meal**

**14% less $meal**

**21% less $meal**

• 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.
