Last steps

Compute the average

2015	2016	2017	2018	2019	Sum	Average
-34	-29	-31	-31	-27	-152.0	-30.4

Compute the Upper Control Limit

Simply compute the standard deviation and multiply by 3 and add to the average: -24.4

Compute the Lower Control Limit

Simply compute the standard deviation and multiply by 3 and subtract from the average: -36.4

For the lines, you have the data necessary to plot the chart.

THIS chart shows what the school system "wants"

NOT what school board members want.

NOT what superintendents want.

More about this chart.

Students would perform better the more years in school IF the follow-the-schedule method wanted that.

But that's not what it "wants"...and it's not a coincidence this pattern repeats (repeatedly).

The system (the follow-the-schedule method) "wants" schools to perform poorer, relative to grade level, the more years students spend in public school.

• Any result above zero is proficient; below is not proficient.

Rowland Unified math proficiency

Zero+ meets standard.
