Mean, Median & Mode Calculator
Instant stats for any list of numbers
Paste numbers in any arrangement — commas, spaces, semicolons, tabs or line breaks all work as separators — and ten summary figures appear immediately as you type: how many values there are, their sum, the mean, the median, the mode, the sample standard deviation, the variance, and the minimum, maximum and range. Two details matter for anyone using these numbers in coursework. The standard deviation and variance use the sample formula, dividing by n minus one rather than n, which is the correct choice when your list is a sample drawn from a larger population. And the mode reports every value tied for the highest count rather than picking one arbitrarily, so a bimodal dataset shows you both. A dataset with no repeats says so instead of returning an arbitrary number.
Paste a list of numbers and get count, sum, mean, median, mode, range, minimum, maximum and standard deviation at once. The everyday workhorse for quick data analysis.

How to use Mean, Median & Mode Calculator
Type or paste your numbers into the text area, separated by commas, spaces, semicolons or newlines.
Read the count and sum first to confirm the parser picked up every value you intended.
Check the mean and median side by side — a large gap between them is a quick signal of skew in the data.
Use the range, minimum and maximum to sanity-check for typos, and the sample standard deviation for spread.
- Accepts commas, spaces, semicolons, tabs and newlines as separators, so you can paste straight from a spreadsheet column or a copied list.
- Non-numeric fragments are dropped rather than throwing an error, so a stray label in the middle of a paste does not lose the whole dataset.
- Standard deviation and variance use the sample formula (dividing by n−1), matching how a sample of a larger population is normally reported.
- When several values tie for the highest frequency, the mode lists all of them, and a list with no repeats reports that plainly.
- A student checking a statistics assignment confirms the mean, median and sample standard deviation by hand before submitting.
- A QA analyst pastes a batch of response times to see the average, the spread and whether any outliers sit in the maximum.
- An office manager summarises a list of monthly figures to report a typical month without a spreadsheet.
