A survey recorded the value 0 two times, the value 1 three times and the value 2 four times. What is the median of these nine values?

In order the nine values run 0, 0, 1, 1, 1, 2, 2, 2, 2, so the middle of the nine falls in the fifth place, which lies inside the run of 1s. Answering 2 because it was recorded most often confuses the most common value with the central one, and only four of the nine values sit above the fifth place.
