Here's how to find it:
-
Add all the numbers together.
-
Divide the sum by the total number of values in the set.
For example, if you have the numbers 2, 3, 5, and 7, you would:
-
Add them together: 2 + 3 + 5 + 7 = 17
-
Divide the sum by the number of numbers (4): 17 / 4 = 4.25
So, the average of 2, 3, 5, and 7 is 4.25.
This method works for any set of numbers, whether they are whole numbers, decimals, or even negative numbers.
Here are some additional things to keep in mind:
-
There are other types of averages besides the mean, such as the median (the middle number) and the mode (the most frequent number).
-
If you're working with a large set of numbers, you can use a calculator or spreadsheet software to find the average.
