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.

How does the outlier effect the mean median and mode in a set of data?
There would be a difference to the median. The old number wouldn't be the median but the mode wouldn't change. If the outlier is a high value, it will cause the mean value to shift to the higher side, while a low valued outlier will drop the mean value to a lower number.

Define mean median and range?
The mean is the average, the median is the middle, and the range is the difference between largest and smallest number. These terms are generally used in math.
What does the term of median mean in math?
The median is the middle value of a list of numbers. In [1,6,34] the median value is 6.
What does mean mean in the term of math?
The median is the middle value of a list of numbers. In [1,6,34] the median value is 6.
What is the difference between the mean and the median of the numbers 27 27 29 32 and 35?
Mean = (27+27+29+32+35)/5 = 150/5 = 30 Median = 29 Difference = 1
What does middle value mean?
The median
What is the median of 23?
As 23 is a single number, its median is itself. If you meant 2 and 3, then the median is 2.5, the value halfway between them, which in this case is also the mean of the two numbers.
Why would you use median instead of mean?
You would use median instead of mean because the median doesn't find the average, it finds the middle value. Even if its not the middle of the range (the exact middle value between the lowest number and the highest number) it still is near to the middle value. The mean finds the average of all the numbers, like when a teacher average's her students' grades. Median is better to use when finding the middle value, not the average.
