What is the median of the numbers 4, 7, 9, 12, 15, 18 ?

  • A.9
  • B.10.5
  • C.12
  • D.13.5

Answer: B

Correct answer: 10.5

The values are already in ascending order and there are six of them, an even count, so the median is the mean of the third and fourth.

\[\frac{9 + 12}{2} = 10.5\]

With an even number of observations the median need not be one of the values in the list.
