>From wikipedia <https://en.wikipedia.org/wiki/Median>.
If there is an even number of observations, then there is no single middle
value; the median is then usually defined to be the mean
<https://en.wikipedia.org/wiki/Arithmetic_mean> of the two middle values [1]
<https://en.wikipedia.org/wiki/Median#cite_note-StatisticalMedian-1> [2]
<https://en.wikipedia.org/wiki/Median#cite_note-2> (the median of {3, 5, 7,
9} is (5 + 7) / 2 = 6), which corresponds to interpreting the median as the
fully trimmed <https://en.wikipedia.org/wiki/Trimmed_estimator> mid-range
<https://en.wikipedia.org/wiki/Mid-range>.
