Question
Find the median of the following observations: 13, 14,
12, 15, 11, 16, 19, 10, 20, 18, 17Solution
Ascending order of observations: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
Number of observations = 11 (odd number).
Median formula for odd observations:
Median = [(n + 1) ÷ 2]th term
For n = 11, the 6th term is 15.
