Question
Find the median of the following observations: 7, 8,
5, 4, 6, 10, 9, 12, 11, 13Solution
Ascending order of observations: 4, 5, 6, 7, 8, 9, 10, 11, 12, 13
Number of observations = 10 (even number).
Median formula for even observations:
Median = [(n/2)th term + (n/2 + 1)th term] / 2
For n = 10, the 5th and 6th terms are 8 and 9.
Median = (8 + 9) / 2 = 8.5
