Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -63 | -62 | -55 | -63 | -65 | -308.0 | -61.6 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -52.6
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -70.6
For the lines, you have the data necessary to plot the chart.

THIS chart shows what the school system "wants"
PLUS a "special" or "outside" cause of variation: wealth/poverty.
NOT what teachers 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.
