Example Question #111 : How To Find Mean
Find the mean given the following dataset:
In order to find the mean, or the average, we will need to sum all the numbers in the set and divide the quantity by the number of numbers in the set.
Add the numerator.
This fraction cannot be simplified any futher.
The average is:

Average is another way of describing mean. The mean represents the "central" value of a set of numbers. This is achieved by summing the numbers of a set and dividing it by the number of numbers in the set.
In this problem, we are given five scores. In order to begin this problem, we must take the sum of these scores.
Now in order to find the mean, we must divide this number by the number of scores.
Example Question #112 : How To Find Mean
Find the mean of the following numbers:
The mean, or average, of a set of numbers is found by using the following formula.
We get
Example Question #113 : How To Find Mean
Find the mean of the following data set.(Round to the nearest whole number)
Find the mean of the following data set.(Round to the nearest whole number)
To find the mean, add up all the terms and then divide by the total number of terms.
In this case, we have 9 terms, so we get...
So our answer is 33.
