Arithmetic Mean
Provide a sequence of numbers — comma or space as separator and read the average along with the sum and the number of elements.
How do I use this page?
- Fill in the fields in the form above — the result recomputes at once, with no page reload.
- Under the result you will find the interpretation scale, if the calculator has one: it says which range your value fell into.
- The formula we use is shown lower on this page — you can check the arithmetic yourself.
- To compute the same for another game or variant, change it in the select field — prices and pools update automatically.

Theory — what is the arithmetic mean?
The arithmetic mean is the simplest measure of the centre of a set of numbers. It is calculated by summing all the values and dividing the result by their count — for grades 4, 5, 3, 5, 4 the sum is 21, and with five elements the average is 4.2. The calculator performs exactly this calculation once numbers separated by commas or spaces are entered, also showing the sum and element count. The result describes typical data well, but a single extreme value can distort it significantly.
