The median pay is the average income of a group of individuals. To determine this figure, the salaries of the members in the group are ordered from low to high, and the middle value is used as the median salary.
Example
If the income of ten persons, arranged from low to high, is 7, 8, 8, 9, 10, 11, 12, 14, 15, 20 million VND, then the group's median pay is 11 million.
