Mean earnings divide an earnings total by the relevant employee count under the stated method. The median identifies the middle of a distribution. They answer different questions rather than replacing each other.
Consider five hypothetical monthly salaries: AZN 600, 700, 800, 900 and 7,000. Their total is AZN 10,000 and their mean is AZN 2,000. Four of the five people earn less than the mean. There is no arithmetic error: one high salary shifts the average. The mean does not establish what most people earn.
Put the same salaries in order: the middle observation is AZN 800. That is the median. With an even number of observations in a simple unweighted example, average the middle two. Official surveys may use weights. The median is less sensitive to a few high incomes, but cannot describe the whole distribution.
| Measure | Example result |
|---|---|
| Mean | AZN 2,000 |
| Median | AZN 800 |
| Minimum | AZN 600 |
| Maximum | AZN 7,000 |
Employees’ wages, all residents’ incomes and salaries advertised in vacancies are different datasets. Full-time versus part-time employment and gross versus take-home pay also matter. A vacancy study’s median must not be called Azerbaijan’s national median wage. Business owners’ income is not automatically part of an employee-earnings measure.
A larger share of workers in high-paying industries can increase the mean even if individual continuing workers’ salaries do not change. This is a composition effect. Assessing living standards also needs distribution, employment and price information, which may not all be released at the same time.
Check period, coverage, nominal versus real terms and gross versus net pay. If the source does not publish a median, it cannot be recovered from the mean alone. The responsible interpretation is that the average does not describe the typical salary of every reader.
No. The most frequent value is the mode; the median is the middle of an ordered distribution.
No. Distributional data or individual observations and the appropriate method are needed.
