Median vs. Mean. Median is often confused with another statistic called the mean, or average. The mean of a data set is equal to the sum of all the data values divided by the total number of values in the data set.Consider a data set consisting of the following numbers: 1, 8, 9, 10 and 12.hen a data set has an even number of values, the average of the two values in the middle is usually used as the median. Median salary is simply the median of a set of salary data.
average salary is a pretty generic term and does not tell you how the number is computed. Usually, but not always, it would be the sum of the salaries divided by the number of salaries. This is known as the mean. The median salary is the middle value.That is to say, if you listed all the salaries from lowest to highest, the median would be right in the middle. A more precise statistical definition might say it is the value that separates the higher half of a sample or a probability distribution from the lower half.he median salary in Russia is $1,000 per month. Salaries in the  Russian Federation are a little bit higher at $1,200 per month.
