Find the median of the following data. 15, 30, 20, 10, 25, 35, 18, 21, 28
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 21
15, 30, 20, 10, 25, 35, 18, 21, 28
Arrange the following in descending order -
10, 15, 18, 20, 21, 25, 28, 30, 35
Number of observations = 9 (odd)
Median = [[(n + 1)/2 ]th observation = [(9 + 1)/2]th term = 5th term = 21
