Compute the average
| 2015 | 2016 | 2017 | 2018 | 2019 | Sum | Average |
|---|---|---|---|---|---|---|
| 0.0 | 0.0 |
Compute the Upper Control Limit
Simply compute the standard deviation and multiply by 3 and add to the average:
Compute the Lower Control Limit
Simply compute the standard deviation and multiply by 3 and subtract from the average:
For the lines, you have the data necessary to plot the chart.
THIS chart shows what the school system "wants"
