SAT question 9d935bd8 (Distributions, Center & Spread)

Question

A survey was given to residents of all 50 states asking if they had earned a bachelor's degree or higher. The results from 7 of the states are given in the table above. The median percent of residents who earned a bachelor's degree or higher for all 50 states was 26.95% . What is the difference between the median percent of residents who earned a bachelor's degree or higher for these 7 states and the median for all 50 states?

College Board · Accepted Answer

The correct answer is B. Choice B is correct. The median of a set of numbers is the middle value of the set values when ordered from least to greatest. If the percents in the table are ordered from least to greatest, the middle value is 27.9% . The difference between 27.9% and 26.95% is 0.95% .

CookSAT · Answer

Note: The median function directly computes the middle value of the seven percentages. Subtracting 26.95 gives the difference.
