Much has been written about the relationship between students’ SAT test scores and their family’s income.  Generally speaking, there is a strong positive correlation between income and SAT scores.  Consider and discuss the following questions as you respond:

• Is this correlation evidence that having a high family income causes one to have high SAT scores?
