Average Calculator

Find the mean, median, mode, range and sum for any set of numbers.

How to Use This Calculator

Enter numbers separated by commas, spaces or new lines. Empty entries are ignored. Results update for any number of values, from a handful to thousands.

Mean — the classic average; sensitive to extreme outliers.
Median — the middle value; robust to outliers.
Mode — the value that appears most often.

Frequently Asked Questions

What is the difference between mean and median?

The mean adds everything and divides by the count. The median is the exact middle of the sorted list — one huge value can drag the mean up while the median barely moves.

Why are mode and range useful?

Mode shows the most common value, great for categorical data. Range shows spread — the gap between the smallest and largest values.

Can there be multiple modes?

Yes — if two or more values tie for the highest frequency, all of them are modes.

What does it mean if mean > median?

Usually a right-skewed distribution — a few large values pull the mean up, as with salaries.

Practical Example

For the scores 12, 15, 15, 22, 27, 29, 31:

Mean = (12+15+15+22+27+29+31) ÷ 7 = 151 ÷ 7 ≈ 21.57
Median = 22 (the 4th value when sorted)
Mode = 15 (appears twice)
Range = 31 − 12 = 19

What Your Results Mean

Mean — the balance point of your data; drags toward extreme values.
Median — the midpoint; unaffected by outliers, so often used for skewed data like incomes.
Mode — the most repeated value, useful for categories and counts.
Range — the simplest measure of spread.
