---|---|---|---|---|---|---|
-64 | -60 | -60 | -38 | -37 | -259.0 | -51.8 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -12.8
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -90.8
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 teachers want.
NOT what principals want.
NOT what parents want.





• 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.
