Answer

Explanation:

Step1: Recall median formula

For a set of $n$ data - points arranged in ascending order, if $n$ is odd, the median is the $\left(\frac{n + 1}{2}\right)$-th value. Here $n=13$.

Step2: Calculate the position of the median

$\frac{n + 1}{2}=\frac{13+1}{2}=7$.

Step3: Find the median

The 7 - th value in the ordered data set $15,18,21,22,26,28,32,39,44,48,54,55,69$ is $32$.

Answer:

$32$
