Mean, Median, Mode Calculator
Calculate mean, median, mode, range, count, and sum from a list of numbers. Accepts comma, space, or newline separated values.
Mean, median, mode, and more
This calculator computes six descriptive statistics from a list of numbers at once. The mean is the sum of all values divided by how many there are. The median is the middle value when the numbers are sorted — or the average of the two middle values for an even-length list. The mode is the value that appears most often; if all values are unique there is no mode. Range is the difference between the largest and smallest values. Enter numbers separated by commas, spaces, or line breaks — the format does not matter.
All computation happens locally in your browser. You can paste data directly from a spreadsheet column (newline-separated) or a comma-separated list from any source.
FAQ
What is the difference between mean and median? The mean is sensitive to outliers; a single very large value can skew it. The median is the true middle value and is more robust when the distribution is skewed.
Can a dataset have more than one mode? Yes. If two or more values tie for highest frequency, all of them are returned as modes. If every value is unique, there is no mode.
Does order matter? No. The statistics depend only on the values, not the order you enter them.
