Right Answer is: C
SOLUTION
Given:
The height of 9 students are = 150, 165, 140, 144, 145, 142, 147, 139, 143
Formula:
Median = [(n + 1)/2]th term If n = odd number after arranging data in ascending or descending order.
Calculation:
Arrange the data in ascending order = 139, 140, 142, 143, 144, 145, 147, 150, 165
n = 9 (odd number)
Median ⇒
⇒ [(9 + 1)/2]th
⇒ (10/2)
⇒ 5th
⇒ 144
