The 2008 SAT Math scores (see table above, click to enlarge) reveal statistically significant ethnic differences. Difference-of-means tests (not reported here) reveal that Asians score significantly higher on average than Whites, who score significantly higher on average than American Indians, who score significantly higher on average than Mexicans, who score significantly higher than other Hispanics, who score significantly higher than Puerto Ricans, who score significantly higher than Blacks/African Americans. All differences are statistically significant at the 1% level.Additionally, gender differences on the math SAT exist for all ethnic groups, see table below. For each major ethnic group (Asian, White, American Indian, Other Hispanic, Mexican, Puerto Rican and Black), the mean score for males on the 2008 SAT exam are statistically significantly higher (1% level) than the mean score for females.
In many cases, the ethnic differences on the SAT math exam outweigh the gender differences. For example, Asian females score significantly higher on average than males of any other ethnic group, white females score significantly higher than males of any ethnic group except Asians, American Indian females score significantly higher than black or Puerto Rican males, and females from all ethnic groups except black/African-American score significantly higher than black males. All significant levels are 1%.Bottom Line: There are statistically significant ethnic and gender differences on the SAT math exam.
