Answer
$28$
Work Step by Step
The median of $n$ numbers is the middle number of the numbers when they are in order (and the mean of the middle $2$ numbers if $n$ is even).
The data items in increasing order are: $16, 22, 28,28, 34 $
Here we have $5$ items, thus the median will be the $3$rd item, which according to the list is: $28$
