find the median of this data set: 15, 17, 14, 16, 18

Explanation:

Step1: Sort the data set

Sort the numbers in ascending order: $14, 15, 16, 17, 18$

Step2: Find the median

For a data set with $n = 5$ (odd number of elements), the median is the $\frac{n + 1}{2}$-th element.
$\frac{5+ 1}{2}=3$rd element.
The 3rd element in $14, 15, 16, 17, 18$ is $16$.
