When a data set is skewed, the mean and the median disagree, and the median is usually the more honest summary. Incomes are the standard example: a few very large values pull the mean well above what a typical person earns.

About the Mean Median Mode Calculator

Mean Median Mode Calculator gives the three averages and the spread measures around them from any list of numbers. Values can be separated by commas, spaces, tabs or new lines, so a column copied out of a spreadsheet pastes in without reformatting.

The three averages answer different questions, and the gap between the mean and the median is the quickest diagnostic a data set offers. When they are close, the data is roughly symmetric and the mean is a fair summary. When they diverge, the data is skewed and the mean is being dragged by extreme values -- which is why median income is reported rather than mean income.

The mode is reported as 'none' when nothing repeats, rather than invented. Where several values tie for most frequent, all of them are listed: a data set can genuinely be bimodal, and hiding that behind a single figure loses the most interesting thing about it.

The page shows its working, not just its answer. Where there is a formula it is printed with your own numbers substituted in, so you can check the result rather than take it on trust -- which is the difference between a calculator you can use for something that matters and one you cannot.

Everything runs inside your browser. What you type is never uploaded, never logged and never stored, and the calculator keeps working if your connection drops after the page has loaded.

How to use the Mean Median Mode Calculator

  1. Choose round results toThe fields below change to match what you pick, so only the figures that matter to your case are asked for.
  2. Enter your numbersDecimals are fine, and thousands separators are accepted and ignored.
  3. Read the mean, median and modeThe figures update as you type. The Calculate button is there if you would rather press something, but nothing waits for it.
  4. Copy or check the resultCopy the summary with the copy button, or open the table to check it row by row and read the formula with your own numbers in it.

Features

  • Shows mean, median, mode, range and values together, so you are not running it twice
  • A results table you can read across
  • Prints the formula with your own figures substituted in
  • Updates as you type, with no button to press and no page reload
  • Copy the result in one click
  • Free, no sign-up, and it runs entirely in your browser

Who uses this tool

The mean median mode calculator is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

  • Summarising a column of survey results
  • Checking whether a data set is skewed
  • Finding the quartiles and interquartile range
  • Getting a quick five-number summary for a report

Frequently asked questions

What if there is no mode?

Then no value repeats, and the calculator says so rather than picking one arbitrarily. A data set with no repeats has no mode.

Which average should I report?

The median for skewed data, the mean for symmetric data, and the mode when you care about the most common category. Reporting the mean and the median together is often the most honest choice.

How are the quartiles calculated?

By linear interpolation between the closest ranks, which is the method spreadsheets use for PERCENTILE.INC. Other conventions exist and give slightly different answers on small samples.
