Last steps
Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 17 | 38 | 39 | 38 | 28 | 160.0 | 32.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average: 59.0
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average: 5.0
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.
