The age of some students is given in years as 12, 13, 16, 18,14, 19, 13, 17, 15 and 11. The median age (in years) of the students is:
14.5
Arrange the ages in ascending order: 11, 12, 13, 13, 14, 15, 16, 17, 18, 19.
There are 10 students (an even number).
The median is the average of the middle two numbers (14 and 15).
Median = (14 + 15) / 2 = 14.5
