Is the algorithm of recruiting monthly salary average or median?

I think the median value is more valuable in this case. Because the average is greatly influenced by the extreme value, and the median can better reflect the middle level of the data and avoid the influence of the extreme value. If the average is pulled up or down by extreme values, it may mislead job seekers.

Suppose that in the first quarter, in addition to a large number of jobs with a monthly salary within the normal distribution range, there are also a small number of high-paying jobs, which are the main factors for running a high average. In this case, if job seekers apply for jobs with an average score as the goal, they may find that they cannot match high-paying positions, which will put some pressure on job seekers. The median is the middle value of the data, which can more truly reflect the medium salary level in the job market and provide more valuable guidance for job seekers to find jobs that meet their own level and positioning.

To sum up, although the average can reflect the overall level of the national average recruitment monthly salary, the median can better reflect the general level of the market and is more suitable as a reference index for job seekers when looking for a job.
