#### Last steps

##### Compute the average

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

-231 | -192 | -206 | -199 | -828.0 | -165.6 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **-159.0**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **-255.0**

##### 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% | 55% | 100% | 100% | 100% |

Data source | 2015 data file | 2016 data file | 2017 data file | 2018 data file | 2019 data file |

### 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

**39% less $meal**

**55% less $meal**

**100% less $meal**

**100% 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.
