Mean, Median, Mode & Range Calculator
Paste a list of numbers to find the mean, median, mode, range, sum, and count instantly. Handles any separator — commas, spaces, or new lines.

Mean = sum ÷ count. Median = the middle value once the numbers are sorted (the average of the two middle values when the count is even). Mode = the value that appears most often. Range = maximum − minimum.
Frequently Asked Questions
How do I find the mean of a list of numbers?
Add up all the numbers and divide by how many there are. For example, the mean of 2, 4, 9 is (2 + 4 + 9) ÷ 3 = 5. The mean is what most people call the average.
How do I find the median?
Sort the numbers from smallest to largest and take the middle one. If there is an even number of values, the median is the average of the two middle values. For 1, 3, 5, 8 the median is (3 + 5) ÷ 2 = 4.
What is the mode, and can a set have more than one?
The mode is the value that appears most frequently. A data set can have no mode (if every value is unique), one mode, or several modes if multiple values tie for the highest count. This calculator lists all of them.
What is the range?
The range is the difference between the largest and smallest values: range = maximum − minimum. It's a quick measure of how spread out the data is.
When should I use the median instead of the mean?
Use the median when your data has outliers or is skewed, because a few extreme values can pull the mean far from the typical value. For example, with incomes the median is usually more representative than the mean.
