Calculate the arithmetic mean based on the entered data.
To calculate the arithmetic mean, sum all the numbers and divide the result by their amount.
Let's assume we have 2, 4, and 6 numbers, and we want to calculate the arithmetic mean.
Arithmetic mean = (2 + 4 + 6) / 3 = 4
As you can see, we added all the numbers, and then we divided their sum by their total amount, which is 3.
| Numbers | Calculations | Result |
|---|---|---|
| 2, 8 | (2 + 8) / 2 | 5 |
| 10, 20 | (10 + 20) / 2 | 15 |
| 2, 4, 7, 10 | (2 + 4 + 7 + 10) / 4 | 5.75 |
| 3, 5, 8, 12, 20 | (3 + 5 + 8 + 12 + 20) / 5 | 9.60 |
| 10, 100, 1000 | (10 + 100 + 1000) / 3 | 370 |
