Each state has its own approach to which high school students should take the SAT. Not surprisingly, the participation rate has a strong bearing on a state’s average score. In states where a very small percentage of students take the exam – usually only those who are college bound – the average score is much higher. In states where it is routine for almost all students to take the test, regardless of their plans for post-secondary education, average scores are lower.
This scatter plot shows participation rate vs average combined SAT score. The r^2 value (coefficient of determination) is 0.81; the linear regression is statistically significant (p-value «0.01). In most states, math is the subject in which students have the highest average score. There were no states in which writing alone was the best subject for students; it tied for the highest with math in two states.

Inspiration is fickle and difficult. We all strive for those bright “Aha!” moments, whether we work in a creative or logical field. While it’s not a process you can control entirely, there are ways to enable and encourage your brain to have more of those epiphanies when you understand how they work.
