Which school do you want to support?
The last lesson mentioned that, on average, about a third of California's students do not finish high school. Averages are useful but dangerous abstractions. Imagine that you are in a Starbucks when Bill Gates walks in.
On average, you just became a billionaire. Right?
In order to make sense of averages, it is useful to find meaningful subgroups within a data sample. In the Starbucks example, we can probably refine our understanding by taking Bill Gates out of the sample - he is clearly an outlier. But that still would give us a flawed understanding of the wealth in front of the counter vs. behind the counter.
Let's leave the coffee shop and return to education. The classic symptom of educational failure is when a student stops coming to school. Students that "drop out" are not random – they are disproportionately African American and Latino, and they disproportionately come from low-income families. (Persistent, systematic differences in educational attainment by ethnicity, income or gender are known as achievement gaps, a subject much studied in California by Education Trust-West.)
In the dry, neutral language of social science: low educational attainment is correlated with various social costs, including unemployment, low taxable earnings, homelessness, crime, and poor health.
"When a black male graduates... on average taxpayers benefit to the tune of about $294,000." -RAND
It's pointless to be neutral, though. When children don’t get the education they need, everyone loses. The cost of failure is enormous, and a variety of scholars have tried to quantify it.
Taxpayers are not the only ones to benefit, of course, when an at-risk student persists in school. The biggest beneficiary is the student. Even leaving crime out of it, the personal stakes of educational attainment are huge. According to year after year of data from the US Census Bureau, economic prospects improve dramatically with every additional year of educational attainment.
The College Board updates its ambitious Education Pays report every three years. According to the 2013 report, "during a 40 year full-time working life, the median earnings for bachelor’s degree recipients without an advanced degree are 65% higher than the median earnings of high school graduates.”
As in the coffee shop, averages can lie. The Education Pays report does a good job of sketching the broad systematic variations. For example, at any given level of educational attainment, earnings for women and minorities lag earnings for white men. In 2010, Full Circle Fund (the sponsor of Ed100.org) released a set of policy recommendations under the one-word title "EACH." The focus was on creating new policies that support thinking about education in terms of each student instead of in terms of averages, or even subgroups.
