Solution

Step 1: First we arrange the given data in ascending order.
Given , $15, 6, 16, 8, 22, 21, 9, 18, 25$
$6, 8, 9, 15, 16, 18, 21, 22, 25$
Here, total number of observations $= 9$
Since, $9$ is an odd number
Step 2: Find the median
$∴ M e d i a n = (\frac{n + 1}{2}) t h$ observation, where, $n$ is total number of observations
$= (\frac{9 + 1}{2}) t h$
$= (\frac{10}{2}) t h$
$= 5 t h$ observation
$= 16$
Hence, the median of the given data is $16$ .
