In order to find the median, you have to rearrange the numbers.
$12, $26, $28, $31, $34
Now that the numbers are rearranged, you can find the median.
Median: The middle value in an ordered set of numbers.
$12, $26, <em>$28,</em> $31, $34
The bold means that the numbers are crossed out and the italicized number is the median.
So, the median of the numbers is $28.
