The average, or mean, is found by adding up all the numbers in your set and then dividing by how many numbers there are. Here's the basic formula:
Average = (Sum of all numbers) / (How many numbers)
For example, let's say you have the numbers 10, 15, and 25. Add them up (10 + 15 + 25 = 50), then divide by 3 (since there are three numbers). The average is 16.67.
This method works for any group of numbers-test scores, daily temperatures, or even the number of steps you walk each day. Just remember: add everything together, then divide by the count.
Next time you want to get a sense of the "middle" value in a set, try calculating the average. It's quick, easy, and gives you a clear picture of your data!
