Solution

The correct option is B 23
After arranging the data in ascending order, we get:

0, 3, 8, 12, 15, 19, 23, 24, 39, 53, 57, 64, 65.

Here, n = 13 = Odd
$M e d i a n = \frac{(n + 1)}{2}^{t h}$ observation

$= \frac{(13 + 1)}{2}$
$= 7^{t h} o b s e r v a t i o n$
$= 23$

Therefore, median of the given data is 23.
