Answer 2

$\sf \Large Solution!!$

Organize the following data (observations) in ascending order.

9, 11, 12, 14, 16, 17, 20, 20, 21, 25, 28

So, there are total 11 observations, which is an odd number.

$\sf Median=\dfrac{n+1}{2}^{th}term$

Here 'n' is the number of observations.

$\sf Median=\dfrac{11+1}{2}^{th}term$

$\sf Median=\dfrac{12}{2}^{th}term$

$\sf Median=6^{th}term$

The 6th term is 17, so the median = 17
