The difference between the median and average monthly salary of national average recruitment.

When analyzing the data of the national average recruitment monthly salary in the first quarter, both the median and the average have reference value, but the information expressed may be different.

First of all, the median refers to a set of data arranged from small to large (or from large to small), which is located in the middle. In statistics, median is considered as one of the important parameters to measure the central trend of a set of data sets. Compared with the average, the median can eliminate the influence of extreme value and better reflect the typical level of this group of data. So, if there is a big fluctuation in this set of data or? There are many extreme values, so it is more scientific and reasonable to use the median to represent the central trend of this group of data than the average.

Secondly, the average value refers to the sum of all the values in a set of data divided by the number. Different from the median, the average is sensitive to extreme values, that is, if there are extreme values in this set of data, the average will be affected by extreme values and deviate from the real situation of the data. Therefore, if this set of data is relatively stable and there is no obvious extreme value, it is more appropriate to use the average value to represent the central trend of this set of data than the median value.

Back to the national average monthly salary data in the first quarter, if we only pay attention to the central trend of this set of data, then both the average and the median can be used. However, whether there are extreme values in this set of data and the degree of normal distribution will affect their reference values.

First of all, for the national average recruitment monthly salary data in the first quarter, they are composed of the salaries of many different types of positions. Therefore, there may be some fluctuations or extreme values in these salaries. In this case, it is more appropriate to use the median to represent the central trend of this set of data.

Secondly, if this set of data shows obvious normal distribution characteristics, that is, most of the salary is concentrated near the average level, and the number of extreme values is relatively small, then it is more appropriate to use the average value to represent the central trend of this set of data.

Generally speaking, when analyzing the data of national average monthly salary in the first quarter, the median and average are of reference value. Which index to choose needs to be considered comprehensively according to the characteristics of the data itself. If the data fluctuates greatly or has many extreme values, it is more appropriate to use the median to represent the central trend of this group of data; However, if the data show obvious normal distribution characteristics, it is more appropriate to use the average value to represent the central trend of this group of data.
