Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| -88 | -70 | -69 | -82 | -78 | -387.0 | -77.4 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: -53.4
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: -101.4
For the lines, you have the data necessary to plot the chart.

Zero+ meets standard.
80% less $meal
84% less $meal
87% less $meal
86% less $meal
89% 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.
