Which is more accurate, the average wage or the median wage?
First of all, the average value is the sum of all salary values divided by the number of data, which can reflect the average level of the whole data set. Median is the middle number of all data sorted by size, which can reflect the middle level of data set. Therefore, the average reflects the average level of a population more sensitively, while the median reflects the middle level of a population more sensitively.
For the recruitment monthly salary data, if the data distribution is relatively uniform, then the average and median are relatively close, and the reference values of the two are not much different. However, if the data distribution is uneven, the average and median will be very different. At this time, it is necessary to choose which index as a reference according to the specific situation.
For example, if there are extremely high and extremely low abnormal values in the recruitment monthly salary data, the average value will be affected by these extreme values and lose the ability to reflect the overall level. At this time, the median is more valuable. In addition, if the data distribution is skewed, such as the right skewed distribution, the mean will be pulled up to the right by the long tail, and the median will not be affected by the long tail, which can better reflect the middle level of the data set.
To sum up, both the average and the median have certain reference value, and which one is more valuable depends on the situation. For the recruitment monthly salary data, if the data distribution is relatively uniform, then the average and median are relatively close, and the reference values of the two are not much different; However, if the data distribution is uneven, you need to choose which index as a reference according to the specific situation.
