# Mean Part 2

Mean is the average of a group of numbers. It is calculated by adding all numbers in the group, and dividing the sum by the total count of the numbers in the group.

**For example:** Consider the group of numbers {4, 3, 4, 5, 8, 1, 1, 4, 3, 2}.

Sum of all the numbers = 4 + 3 + 4 + 5 + 8 + 1 + 1 + 4 + 3 + 2 = 35

The total count of the numbers is 10.

Now, divide the obtained sum by the total count of the numbers.

35 ÷ 10 = 3.5

So, the mean of the group of numbers is **3.5**.
