Average Calculator — Mean, Median & Mode
Paste or type a list of numbers — test marks, monthly bills, daily sales — and get the mean, median, mode and range in one go.
Updated
Formula
Mean = Sum of values ÷ Number of values
Median = middle value when sorted
Mode = most frequent value
With an even count, the median is the average of the two middle values. A list can have more than one mode, or none if every value appears once.
Examples
Marks: 72, 85, 90, 66, 85, 78
Average (mean) of 6 numbers = 79.3333333333
Monthly bills: 5400 6100 7300 9800
Average (mean) of 4 numbers = 7,150
Important information
- The mean is pulled up or down by extreme values; the median is not. For salaries or property prices, the median often gives a fairer 'typical' figure.
Frequently asked questions
What is the difference between mean and average?
In everyday use they're the same thing: add up the values and divide by how many there are.
How do I find the median?
Sort the numbers. The median is the middle one, or the average of the two middle ones if there's an even count.
Can there be no mode?
Yes — if every value appears exactly once, the list has no mode.
How many numbers can I enter?
Up to 10,000, separated by commas, spaces or new lines.
