Mean, Median & Mode Calculator

Paste in a list of numbers and see the mean, median, mode, range, and more. Handy for checking homework or making sense of a set of test scores.

Separate them with commas or put each number on its own line. Decimals and negative numbers are fine.

How each result is worked out
  • Mean (average): add every number, then divide by how many numbers there are.
  • Median (middle): put the numbers in order and take the middle one. With an even count, average the middle two.
  • Mode (most common): the number that shows up most often. A list can have one mode, several, or none.
  • Range: the largest number minus the smallest.
