Relationship between SAT scores and family Income.
Every year, many test-takers voluntarily give information to the college board on family income among other things. The College Board publishes this information and uses it to make correlations such as this one. The graph on the left shows the strong correlation between increasing family income and increasing test scores on the SAT. This graph gives evidence to the fact that a persons socioeconomic origins have an impact on their future academic success.
Enrollment among children in families with an income of 100,000 or more.
This figure was derived from information from the Census bureau and is displayed on the Center of American Private Schools website. The figure attempts to disprove the presentiment that all kids of wealthy families attend private school. However, students enrolled in private school represent 11% of the population, seeing that 20% of kids in families with incomes greater than 100,000 dollars attend private school suggests that the higher the income of a family, the greater chance they will attend a private school. Higher SAT scores are seen for kids attending private schools, as well as children in high income families, as the graph above shows. This further develops a trend pointing to an increased chance for success based on better socioeconomic origins.
Type of High School and SAT participation.
The above table further exhibits the relationship between private school attendance and future success, especially in terms of the SAT, where a large increase in scores is seen from public to private school students. This table can also be used to draw a very loose correlation between income, SAT scores, and private school attendance. However, this data must be contextualized, those attending private schools are most likely preparing for college, where many students in public schools may just be taking the test to see how they can perform, not having prepared in the same manner. This table shows a large disparity between public and private-schooled students scores but must be corrected for those who know they want to apply to college and who have prepared accordingly for the test. Private schools often site results such as this as evidence for their efficacy in the academic world, but this data has then been taken out of context. By the same vein, strong conclusions on the correlation between income, private school, and SAT scores cannot be drawn from this data as it only suggests a trend and a myriad of other factors contribute to this data and the observed results.
