The following are scores obtained by some students in a test: 8, 18, 10, 14, 18, 11, 13, 14, 13, 17, 15, 8, 16 and 13. Find the median score.

Worked solution (try it first)

Put the 14 scores in order: 8, 8, 10, 11, 13, 13, 13, 14, 14, 15, 16, 17, 18, 18.
With an even count, the median is halfway between the 7th and 8th: 13 and 14.
So the median is $\frac{13 + 14}{2} = 13.5$ , option C.
