OpenStudy (chriss):

11

OpenStudy (chriss):

You have an even number of data elements here. So you get your two middle numbers. You then find the center of the second half of the set... again an even number of points so you have to take the two numbers in the middle of the second half, (9 and 13) and average them out... you get 11.
