Question:
The heights (in cm) of 9 students of a class are 148, 144, 152, 155, 160, 147, 150, 149, 145.
Find the median height.
Solution:
Arranging the given data in ascending order:
144, 145, 147, 148, 149, 150, 152, 155, 160
Number of terms = 9 (odd)
$\therefore$ Median $=\left(\frac{n+1}{2}\right)^{\text {th }}$ term
$=\left(\frac{9+1}{2}\right)^{\text {th }}$ term
$=5^{\text {th }}$ term
$=149$
Hence, the median height is 149.
