Description

Here's a simple formula to calculate the mean:

Mean = (Sum of all values) / (Total number of values)

Let's say you have a set of numbers: 5, 10, 15, 20, and 25. To find the mean of these numbers, you would add them together and divide by the total count, which in this case is 5:

Mean = (5 + 10 + 15 + 20 + 25) / 5 = 75 / 5 = 15

So the mean of the set of numbers {5, 10, 15, 20, 25} is 15.
You can use a calculator or a spreadsheet software to easily perform this calculation for larger sets of numbers.
