What this tool does

Paste a list of numbers and get the count, the mean, the median, and the mode. Separate values with commas, spaces, or new lines. The list can hold up to 1,000 numbers, and the values are not weighted.

How to use

  1. Paste the numbers. A blank list is rejected.
  2. Press Calculate.
  3. Read the mean, the middle value, and any mode.

Examples

  • Four numbers with no repeat

    1, 2, 3, 4 has a mean of 2.5, a median of 2.5, and no mode.

  • A repeated pair

    1, 2, 2, 3 has a mean of 2, a median of 2, and a mode of 2. 1, 1, 2, 2, 3 has a mean of 1.8, a median of 2, and modes 1 and 2.

Main features

  • Mean rounded to at most 10 decimal places.
  • Median of an even count is the average of the two middle numbers.
  • More than one mode when several values tie for the highest count.

How it works

The mean is the sum divided by how many numbers you entered. The median is the middle number after sorting, or the average of the two middle numbers when the count is even. The mode is the value that appears most often. If every distinct value appears once, there is no mode. A single number is its own mode.

Tips

  • GPA uses letter grades and credits. Use the GPA Calculator for that, not this list of raw numbers.

Limitations

Up to 1,000 numbers. A token that is not a number rejects the whole list. This page does not weight the values.

FAQ

Is the Average Calculator free?
Yes. You can find the mean, median, and mode of a list here without paying or creating an account.
What is the median of an even list?
The average of the two middle numbers after the list is sorted. 1, 2, 3, 4 has a median of 2.5.
When is there no mode?
When every different number appears the same number of times and more than one number is in the list. 1, 2, 3, 4 has no mode.
Are these numbers sent to a server?
No. The list is calculated in this browser tab. Tools Star Hub does not send those numbers to a server or save them in local storage.
