The mean of a set of numbers is defined to be the quotient of the sum of all the numbers divided by how many numbers are summed. In this instance, (13 + 2 + 15 + 10 + 5)/5 = 9.

The mean is 7.375. You can find this by adding all the numbers in the set then dividing the sum by the amount of numbers in the set.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
Mean - the quotient obtained when the sum of the numbers in a set is divided by the number of addends. Example - the mean of 3,4,7, and 10 is (3+4+7+10)/4=6 So the mean of 3,4,7, and 10 is 6. =] Mean, otherwise known as average, is everything in a set added up together and divided by how many numbers you added up.The mean is the average. It is calculated by adding up all of the numbers in the set and dividing it by the number of numbers in the set.
The word is "average". Formally, to get an average of a set of numbers, you add all the numbers and divide by the size of the set (for example, if you have 10 numbers, you add all of them together and divide the result by 10). The average - which is also know as the "arithmetic mean" - gives you an idea of the "typical" value for the numbers in the set.
In any given set, the mean is the average, which is the total of the numbers divided by how many numbers there are. Ex. (10, 17, 20, 45, 68) 68 + 45 + 20 + 17 + 10 = 160 There are 5 numbers in this set. 160/5 = 32 The mean is 32.
