The mean (arithmetic mean) is the average of all the values in the set. Add the values together and divide by the number of values.
Example : the values 1, 2, 3, 4, and 5
Their sum is 1+2+3+4+5 = 15 and there are five values.
15/5 = 3 so the mean is 3.
(*In some branches of mathematics, the term average has other forms, so the term mean is used to indicate this type of averaging.)

How do you find a mean of a set of numbers?
to find the mean of a set of numbers you have to find the total sum of the data divided by the number of addends in the data.
What is range and mean of a set of numbers?
The mean is the average of the set of numbers. To find it you have to add up all of the numbers in the set and divide by however many numbers there are in the set. For example, if you had the set: 1, 2, 3, then you would add them up to get 6. Since there are 3 numbers you would divide by 3 to get 2. The range is the highest number in the set minus the lowest number in the set. Example: of you have the set: 1, 2, 3, 4, 5, 6, 7, 8, then the range would be 8-1, or 7.
What are the set of numbers in which 8 is the mean median and mode?
One set of numbers for which this is true is {8}.
How Can You Create A Data set With an Median and mean?
a data set in this case can be any collection of numbers you choose. Say we define Set A = {1,2,3,4,5} The Median for Set A is 3. The mean is the sum of the numbers divided by 5 in this case. 15/5 = 3 is the mean of Set A.
How does the mean compare to the median?
The mean and the median are both involved with a set of numbers. The mean refers to the average of the numbers. The median refers to the middle number of the numbers
