The heights (in cm) of 9 students of a class are as follows:
155, 160, 144, 149, 150, 147, 152, 144, 148
Find the median height (in cm).
Answer & explanation
Correct answer: option 4
Given data is :- 155, 160, 144, 149, 150, 147, 152, 144, 148
In ascending order :- 144, 144, 147, 148, 149, 150, 152, 155, 160
Total no. of students = 9
In case of odd numbers ,
Median = ( \(\frac{n + 1 }{2}\) )th term
= ( \(\frac{9 + 1 }{2}\) )th term
= 5th term
i.e. 149
The correct answer is Option (4) → 149
