Use this Mean, Median & Mode Calculator to find the three main measures of central tendency for a set of numbers.
Enter your values to calculate the mean, median, mode, total, and number of values. This tool is useful for schoolwork, surveys, scores, business data, research, and everyday number comparisons.
How to use the Mean, Median & Mode Calculator
- Enter your numbers in the values box.
- Separate each number with a comma, space, tab, or new line.
- Select Calculate.
- Review the mean, median, mode, total, and number of values.
For example, you can enter:
12, 18, 22, 22, 25, 26, 30
Mean median and mode example
Suppose you have the following values:
4, 6, 6, 8, 10, 10, 10, 12
The calculator gives these results:
- Mean: 8.25
- Median: 9
- Mode: 10
Each result describes the data in a different way.
What is the mean
The mean is the arithmetic average of a set of values.
To find the mean, add all values together and divide the total by the number of values.
Mean = Total of all values / Number of values
For the values 4, 6, 6, 8, 10, 10, 10, 12:
Total = 66
Number of values = 8
66 / 8 = 8.25
The mean is 8.25.
The mean can be useful when the values are fairly balanced. It can be affected by unusually high or low values, also called outliers.
What is the median
The median is the middle value after the numbers are arranged from smallest to largest.
If there is an odd number of values, the median is the one number in the middle.
If there is an even number of values, the median is the average of the two middle numbers.
For the values 4, 6, 6, 8, 10, 10, 10, 12, there are eight values. The two middle values are 8 and 10.
8 + 10 = 18
18 / 2 = 9
The median is 9.
The median can be especially useful when one or two extreme values would distort the average.
What is the mode
The mode is the value that appears most often in a data set.
For the values 4, 6, 6, 8, 10, 10, 10, 12, the number 10 appears three times.
The mode is 10.
A data set can have:
- One mode, called unimodal
- Two modes, called bimodal
- More than two modes, called multimodal
- No mode when every value occurs the same number of times
For example, the values 3, 3, 5, 5, 7 have two modes: 3 and 5.
When to use mean median or mode
Use the mean when you need the overall average and the data does not include major outliers.
Use the median when you need the middle value and want to reduce the effect of unusually high or low numbers.
Use the mode when you need to identify the most common value, choice, score, size, or category.
Comparing all three can give a clearer picture of your data than using only one result.
Important notes
This calculator works with positive numbers, negative numbers, and decimals.
Make sure every value is entered correctly. One missing number or typing error can change the result.
Mean, median, and mode describe the centre or most common part of a data set. They do not explain every detail about the data, such as how spread out the values are or whether there are unusual patterns.
Use the Percentage Calculator to compare part of a total, or the Unit Converter to convert measurements before calculating statistics.
