Mean, Median, Mode Calculator
- Add up all the values: 7 + 8 + 10 + 12 + 12 = 49.
- Count the values: n = 5.
- Divide the sum by n: 49 ÷ 5 = 9.8.
- Mean: 9.8
- Median: 10
- Mode: 12 (appears 2 times)
- Range: 5 (largest 12 minus smallest 7)
- 7, 8, 10, 12, 12
- Values below the median: 2, above it: 2. The median splits the data in half.
- The differences from the mean add up to zero, as they should.
- Mode check: 12 appears 2 times, and no other value appears more often.
Mean, Median, Mode Calculator: Find the Average of Any List
This free mean, median and mode calculator works out all three averages from a list of numbers in one go. Paste or type your data, and you get the mean, median, mode, range, sum, count, smallest and largest value, the sorted list and a graph. Each result comes with the working so you can follow it, and the calculation is done with exact arithmetic, so decimals do not drift.
Quick answer: for the numbers 10, 12, 7, 8 and 12, the mean is 9.8, the median is 10 and the mode is 12.
What Are the Mean, Median and Mode?
They are three ways to describe the centre of a set of numbers. The mean is the sum divided by the count. The median is the middle value once the numbers are sorted. The mode is the value that appears most often. They often give different answers, as the table shows, and each is useful in a different situation.
| Data set | Mean | Median | Mode | Range |
|---|---|---|---|---|
| 10, 12, 7, 8, 12 | 9.8 | 10 | 12 | 5 |
| 2, 4, 4, 4, 5, 5, 7, 9 | 5 | 4.5 | 4 | 7 |
| 1, 2, 2, 3, 3, 4 | 2.5 | 2.5 | 2 and 3 | 3 |
| 5, 6, 7, 8, 100 | 25.2 | 7 | No mode | 95 |
How to Find the Mean
Add every value and divide by how many values there are. The mean uses all of your data, so it reacts to every change. That is useful for fair averages, such as marks across several tests, but one extreme number can drag it a long way, as in the last row of the table where a single 100 moves the mean from 6.5 to 25.2.
How to Find the Median
Sort the numbers and take the middle one. With an even count, take the average of the two middle numbers. The median ignores how large the extreme values are, which is why it is the usual choice for household income and house prices.
How to Find the Mode
Count how often each value appears and pick the highest count. A list can have one mode, several modes when values tie, or no mode if every value appears once. The mode is also the only one of the three that makes sense for non-numeric answers such as favourite colours or shoe sizes.
Range and Spread
The range is the largest value minus the smallest and shows how spread out the data is. To measure spread more fully, use the standard deviation calculator. For converting between decimals, fractions and percentages in your results, the percentage calculator and the fraction calculator help, and the scientific calculator covers general arithmetic.
Who Uses It?
Students use it for statistics and maths homework, teachers for class results, and analysts, researchers and small business owners for quick summaries of sales, prices, ratings and measurements. If you also want to grade results, try the grade calculator.
