#### Last steps

##### Compute the average

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

-65 | -52 | -41 | -33 | -35 | -226.0 | -45.2 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-6.2**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-84.2**

##### 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:

2015 | 2016 | 2017 | 2018 | 2019 | |
---|---|---|---|---|---|

Percent | 83% | 88% | 83% | 89% | 93% |

### Just a coincidence? That's absurd.

It's a system that causes this pattern to repeat.

**
THIS chart shows what thefollow-the-schedule method wants.

NOT what teachers want.

NOT what principals want.

NOT what parents want.

*math*proficiency

**66% less $meal**

**78% less $meal**

**74% less $meal**

**78% less $meal**

**80% 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.
