What you can do here

All three on one paste

You do not pick a mode. Mean, median and mode are computed from the same tokens.

No fake mode

If every value appears once, the detail says there is no mode instead of listing the whole set.

Two middle values

An even-sized list does not pick the lower middle only. It averages the two central numbers.

The sequence

How to use the Mean Median Mode Calculator

  1. 1

    Paste the raw list

    Commas, spaces and line breaks all work. Words are ignored; only number tokens are read.

  2. 2

    Sort in your head for the median

    The page sorts a copy. Your original order does not change the median.

  3. 3

    Treat “no mode” as an answer

    If nothing repeats, say there is no mode. Do not invent one by picking the first number.

Worth knowing

  • Mean Median Mode Calculator on Toolspire: the mean is the arithmetic average: the sum divided by how many numbers were parsed.
  • The median is the middle of the sorted list. An even count uses the average of the two middle numbers.
  • The mode is every value that appears most often, and only if it appears more than once. A list of unique numbers has no mode.
  • 1, 2, 2, 9 has mean 3.5, median 2 and mode 2.

Which average a list is asking for

The mean moves when a single outlier moves. The median does not, as long as the outlier stays on the same side of the middle. The mode is about the most common value, and a list can have more than one. School questions that say “find the three averages” want all of these from the same data, which is why they share a page instead of hiding inside the plain average tool.

FAQ

Questions about Mean Median Mode Calculator

Where does Mean Median Mode Calculator run?

Mean Median Mode Calculator runs in this tab on Toolspire. What you type or drop in is not sent to us and is not stored on a server.

Can a list have two modes?

Yes. If two values tie for the highest frequency, both are listed. A list where everything appears once has no mode.

How is the median of an even list found?

Sort the list and average the two central numbers. For 1, 2, 2, 9 the two central numbers are both 2, so the median is 2.

Does the average calculator already do this?

The average tool is the mean. This page adds the median and the mode, which that tool does not report.

Are negative numbers allowed?

Yes. A leading minus is part of the number. The mean can be negative.
