Find the median of the following data. 129.75, 116.6, 12.3, 114.1, 136.6, 118.7, 13.5, 121.3
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 117.65
129.75, 116.6, 12.3, 114.1, 136.6, 118.7, 13.5, 121.3
Arrange the observations in ascending order -
12.3, 13.5, 114.1, 116.6, 118.7, 121.3, 129.75, 136.6
Total number of observations = 8 (even)
Median = [(n/2)th term + (n/2 + 1)th term]/2
Median = [(8/2)th term + (8/2 + 1)th term]/2 = [4th term + 5th term]/2 = [116.6 + 118.7]/2 = 117.65
