Statistically significant contrasts*:
a
For blacks vs whites contrast: differed on age, sex, education and income (P ≤ .05).
b
For blacks vs Puerto Rican Hispanics contrast: differed on education (P ≤ .05).
c
For Puerto Rican Hispanics vs whites contrast: differed on age, sex, education and income (P ≤ .05).
* = ANOVA test for age; Pearson chi-square tests for gender, education, and income.
