#### Last steps

##### Compute the average

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

11 | 19 | 20 | 17 | 14 | 81.0 | 16.2 |

##### Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: **25.2**

##### Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: **7.2**

##### For the lines, you have the data necessary to plot the chart.

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

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

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

NOT what school board members want.

NOT what superintendents want.

*math*proficiency

• 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).

### Students would perform better the more years in school IF the follow-the-schedule method wanted that.

But that's not what it "wants"...and it's not a coincidence this pattern repeats (repeatedly).

#### The system (the follow-the-schedule method) "wants" schools to perform poorer, relative to grade level, the more years students spend in public school.

• Any result above zero is proficient; below is not proficient.
