#### Last steps

##### Compute the average

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

-9 | -8 | -2 | -5 | -1 | -25.0 | -5.0 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **4.0**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-14.0**

##### 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 | 40% | 30% | 33% | 40% | 37% |

### 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

**33% less $meal**

**24% less $meal**

**29% less $meal**

**38% less $meal**

**34% 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.
