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.

What is the difference between mean and median salary?
the mean is the average of all the salaries an the the median is the number that falls in the middle
What is the difference between arithmetic mean and mode?
The mean, median, and mode are all measures of central tendency. For symmetrical distributions they all have the same value. For assymetrical distributions they have different values. The mean is the average and the mode is the most likely value.
Is the median affected by the mean?
The median is the value which seperates the upper and lower half of a set of numbers. The mean is the average value between two or more numbers. In calculating a set of numbers, specifically a set of averages, the median may indeed be effected by the mean.
What does middle value mean?
The median
What can the difference between mean and median values infer. If the mean is 8 655.7 and the median -8 653.0?
First, I will give an example, similar to your question: -11000 -9000 +44000 mean = 8,000 and median = -9000. Symmetrical distributions after infinite sampling will show no difference in mean and median. Large differences are possible with small sample sizes even with symmetrical distributions. If the sample is large and the difference is large, this infers that the distribution is asymmetrical. The skewness of the distribution can be calculated.
