Find the average, middle and most common value of a list as you type. Everything is calculated on your device.
Separate them with commas, spaces or new lines.

How it’s calculated
Mean = 32 ÷ 6 = 5.3333; Median = (4 + 7) ÷ 2 = 5.5
A comma always separates values; it never groups thousands, so write 1000, not 1,000.
Results are rounded to 4 decimal places for display; very small results keep 6 significant digits.
What it does
The mean, median, mode calculator takes a list of numbers and shows:
Mean: the sum divided by the count, the usual average.
Median: the middle value of the sorted list.
Mode: the value or values that occur most often.
Count, Sum, Minimum, Maximum and Range, the spread from the smallest value to the largest.
The results update as you type.
How to use it
Type or paste your numbers into the Numbers box, for example 3, 7, 7, 2, 9, 4. A column pasted from a spreadsheet works too.
Read the mean, then the other results under it.

How it’s calculated
Mean = sum ÷ count. For 3, 7, 7, 2, 9 and 4: 32 ÷ 6 = 5.3333.
Median: the list is sorted (2, 3, 4, 7, 7, 9). With an odd count it is the middle value; with an even count it is the mean of the two middle values, here (4 + 7) ÷ 2 = 5.5.
Mode: the value with the highest count, here 7. When several values share it, each is listed, smallest first. When every value occurs equally often, there is no mode.
Range = Maximum − Minimum, here 9 − 2 = 7.
Results are rounded to 4 decimal places for display; very small results keep 6 significant digits.
Good to know
Commas, spaces, semicolons, tabs and new lines all separate values. A comma never groups thousands, so write 1000, not 1,000.
Use a point for decimals, like 2.5. A value may start with + or −.
Each value must be between −1,000,000,000,000,000 and 1,000,000,000,000,000 (±10^15). The box holds up to 100,000 characters.
If a value isn’t a number, the box says which one and where it is in the list.
When there are more than 10 modes, the 10 smallest are named and the rest are counted.

Everything is calculated in your browser, on your device. Nothing you type is uploaded, and the list isn’t kept: the box starts with the example list each time you open the page.
Frequently asked questions
What is the difference between the mean, the median and the mode?
The mean is the sum of the values divided by how many there are, the usual average. The median is the middle value once the list is sorted. The mode is the value that occurs most often. For 3, 7, 7, 2, 9 and 4 the mean is 32 ÷ 6 = 5.3333, the median is 5.5 and the mode is 7.
How is the median found when the count is even?
With an even count there are two middle values, and the median is their mean. Sorted, 3, 7, 7, 2, 9, 4 is 2, 3, 4, 7, 7, 9, so the median is (4 + 7) ÷ 2 = 5.5. With an odd count the median is the one middle value.
Can a list have several modes, or none?
Yes. When two or more values share the highest count, each is a mode, so 7, 2, 7, 2 and 9 has the modes 2 and 7. When every value occurs equally often, like 1, 2 and 3, the list has no mode. A list with only one distinct value has that value as its mode.
Can I paste a column from a spreadsheet?
Yes. Copy the column and paste it into the box: each value on its own line is read as one number. Commas, spaces, semicolons and tabs separate values too, so a row pasted from a spreadsheet works as well.
Why is 1,000 read as two numbers?
A comma always separates values here, so 1,000 is read as 1 and 000. Write large numbers without separators, like 1000, and use a point for decimals, like 2.5.
