By counting the number of leaves we can see it has 30 elements:
- 5 + 5 + 7 + 6 + 3 + 3 + 1 = 30
We know that the median is the average of the two middle elements if there are even number of elements.
The two middle elements are element 15, which is 33 and element 16, which is 36.
The average of the two is:
- median = (33 + 36)/2 = 69/2 = 34.5
