How do you calculate the mean average?

To calculate the mean average, you add all the numbers in a set together and then divide the sum by the total number of values in the set.

In more detail:

1. Summation: Add all the numbers in the data set.
2. Counting: Count the total number of values in the data set.
3. Division: Divide the sum obtained in step 1 by the count obtained in step 2.

Formula:

Mean = (Sum of all values) / (Number of values)

Example:

Suppose you have the following numbers: 2, 4, 6, 8, 10.

1. Sum: 2 + 4 + 6 + 8 + 10 = 30
2. Count: There are 5 numbers.
3. Mean: 30 / 5 = 6

Therefore, the mean average of the numbers 2, 4, 6, 8, and 10 is 6.
