Average Calculator (Mean, Median, Mode)

Mean is the sum of all values divided by the count - the number most people call "the average." Median is the middle value of a sorted list (or the average of the two middle values when the count is even). Mode is the value that appears most often. All three describe the center of a dataset, but they respond differently to skewed or extreme values.

Use median when your data has outliers that would distort the mean. A single extreme salary in a company can pull the mean far above what most employees earn, while the median barely shifts. Home prices, household incomes, and clinical response times are routinely reported as medians for exactly this reason.

If every value appears exactly once, there is no mode - the calculator shows no mode result in that case. When two or more values tie for the highest frequency, the calculator returns all of them, making the result multimodal.

Range is the largest value minus the smallest value. It gives you a quick sense of how spread out your data is - a range of 2 signals tight clustering, while a range of 200 signals wide variation. It does not describe what happens in between those extremes.

Yes. Separate values with commas, spaces, or new lines. Decimals like 3.14 and negative numbers like -7 both work. Values that are not valid finite numbers are ignored automatically.
