#### Last steps

##### Compute the average

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

28 | 43 | 44 | 41 | 45 | 201.0 | 40.2 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **58.2**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **22.2**

##### 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 | 11% | 14% | 15% | 17% | 16% |

### 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

**7% less $meal**

**11% less $meal**

**12% less $meal**

**14% less $meal**

**14% 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.
