Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 65 | 60 | 61 | 68 | 76 | 330.0 | 66.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 84.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 48.0
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.
NOT what principals want.
NOT what parents want.

Zero+ meets standard.
2% less $meal
3% less $meal
5% less $meal
7% less $meal
4% 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.
