What is the “median” wage of these ten?
$475
$500
$526
$600
$500
The median is the middle number. Half of the ten numbers are larger than (or equal to) the median and half are smaller. The wages have been arranged in ascending order: the fifth is $500 and the sixth is also $500. So half of the numbers are $500 or less and half are $500 or more. The median is midway between these two numbers and is $500.
