How to choose the average and median of recruitment?
First of all, the median is a numerical value in the middle position after a group of data are arranged in order of size. For a set of data, if there are extreme values or uneven distribution, using the median can reduce the influence of these factors on the results. The average value is the result of dividing a group of data by the number of data, which is better for evenly distributed data.
Secondly, the median and the average have their own meanings. Median can be used to reflect the central position of data, such as the age of a group of people, and median can be used to represent the average age of each person. The average can be used to reflect the overall level of data, such as the income of a group of people, and the average can be used to represent the average income level of everyone.
To sum up, the median and average are valuable for the data of monthly salary, but it is more meaningful to choose which index according to the specific situation. If you want to know the actual income level of most people, you can choose the median as a reference; If you want to know the overall level, you can choose the average as a reference. In addition, we need to pay attention to some possible extreme values so as not to affect the accuracy of the results.
