Mean
The value obtained by adding all the numbers in a set (list) of numbers and dividing by the count of numbers in the list.
One way to view the relation between numbers is the mean. Perhaps you have heard of this as the "average." They are one and the same concepts. To compute the mean:
 | Add the elements of the list of numbers |
| Count the elements of the list of numbers |
| Divide the sum of the list by the count of elements in the list. |
The following is a set of examples explaining creation of the mean (average) of a set of numbers.
| List of numbers | Sum of the numbers | Count of the numbers | Mean of the list |
| ( sum / count) | |||
| 70,68,92,67,86,85 | 468 | 6 | 78 |
| 60,75,75,55,60 | 325 | 5 | 65 |
| 30,30, 40,40,50 | 190 | 5 | 38 |
| 12, 15, 13, 11, 14, 14, 19 | 98 | 7 | 14 |
| 3.4, 3.5, 3.6, 3.3, 3.1, 3.8 | 20.7 | 6 | 3.45 |
