Compare data sets using center and spread measures appropriate to distribution shape.
Find the median of each data set and compare the medians
Problem
Find the median of each data set, then compare them: data set \(A~=~3,~7,~9\); data set \(B~=~2,~8,~10\).
Big Picture
What this problem is really about
Order each data set before looking for its center. With an odd number of observations, the median is the single value with equal counts on both sides; find that position in each set, then compare the two middle values directly rather than averaging all the data.
