When weighted mean and combined mean is used?
Since you asked when these "means' are used, I believe you know about them. Where the requirement of deciding and posting a figure for some combined op like NYSE, weighted averages which simple terms mean "mean" is used. Again, this is used in evaluating a student's performance given the specific specialties he / she had opted for. Some subjects may carry less weightages or no weightage at all in the overall scheme. Say for a forensic medicine student, economics could be a subject where she / he has to write an exam paper. But it is not compulsory to score a specified percentage of marks there to be successful in that exam. Like for Engineering students, nowadays, economics and literature is not considered important but invariably have them as subjects for which they have to give an exam. But they don't carry or carry so less weight that performance in those subjects have no impact on results or merit of results. This is weighted mean. And this is established and used where it becomes convenient for the management to asses only the core abilities but also want some knowledge or exposure in some other mundane ones.
Combined mean is used when it becomes convenient for those who want gold and copper chaff and cheese combined and use an arithmetical average.
It's complicated question. Perhaps requires an erudite and elaborate answer. I am sorry. I have no intellectual wherewithal to issue forth a proper answer.

What is the difference between median and mean value?
The Median and Mean are both measures of the central tendency or average of a group of numbers.
The Median is the middle number of set of numbers arranged in ascending order. If there are an even amount of numbers, find the mean of the middle 2 values. For example the median of 6, 3, 9, 2, 12, 3, 54 is 6, determined by arranging the numbers in the following sequence: 2, 3, 3, 6, 9, 12, 54.
The mean is determined by adding up all the numbers and dividing by the number of numbers. So for the example above, the sum of 2+3+3+6+9+12+54 = 89 Divide 89 by 7 = 12.7 So the mean - often called simple average is 12.7
The mean is most often used to find an average.
