Mean

From Wikiversity

In statistics, mean of a series of numbers is obtained by adding the number and dividing the result by the 'number' of numbers.

[edit] Examples and application

1.Find the median of the following set of numbers:

5, 4, 10, 3, 3, 4, 7, 4, 6, 5

First of all, You add the numbers or find their sum, that is:5+4+10+3+3+4+7+4+6+5=51, and then divide them by the number of numbers, that is how many numbers do we have in the set, so when you count them, you will find that they are 10 numbers. Now, you divide the sum by the number: 51\10=5.1. So, the mean of this set of number is 5.1.
