The heights (in cm) of 9 students of a class are 148, 144, 152, 155, 160, 147, 150, 149, 145.

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.
