The median wage is the salary of a given occupation where half the workers earn more than that amount, and half earn less. This information is presented on job postings to help job seekers determine how the salary compares to the amount earned by other workers working the same job. Job Bank preferred indicating the median wage, which is less affected by extremely high or low wages, rather than the average wage which is calculated by adding up all the salaries of a group of people and then dividing that total by the number of people.
