From Pew Research Center:

Science knowledge varies by race and ethnicity in U.S.

BY BRIAN KENNEDY AND SARA ATSKE

U.S. racial and ethnic groups vary significantly in their knowledge of science-related issues, according to a new Pew Research Center survey that quizzed Americans about subjects ranging from life and physical sciences to numeracy and chart reading.

About half of whites (48%) got at least nine of 11 questions correct. In comparison, much smaller shares of Hispanics (23%) and blacks (9%) correctly answered at least nine of the questions.

On average, whites got 7.6 questions correct while Hispanics got 5.1 and blacks 3.7. English-speaking Asians got an average of 7.0 correct answers, but it’s important to note the survey was only conducted in English and Spanish. (Asians are less likely than whites and blacks, but not Hispanics, to be proficient in English.)
