Mean, Median and Mode — What's the Difference?

Mean, median and mode are all types of average — they each measure the centre of a dataset in a different way. Using the right one depends on your data and what you're trying to understand.

Mean (Arithmetic Average)

Mean = Sum of all values ÷ Number of values

Example: (10 + 20 + 30 + 40) ÷ 4 = 25

Median (Middle Value)

Sort values in order — the median is the middle value (or average of the two middle values if there's an even count)

Example: 10, 20, 30, 40, 50 → median = 30

Mode (Most Frequent Value)

The value that appears most often in the dataset

Example: 10, 20, 20, 30, 40 → mode = 20

When to Use Each Type of Average

Average Type	Best Used When	Limitation
Mean	Data is evenly distributed without extreme outliers	Skewed by very high or low values
Median	Data contains outliers or is skewed (e.g. house prices, salaries)	Ignores the magnitude of other values
Mode	Finding the most common value (e.g. most popular shoe size)	May not exist or may not be unique

For example — the average UK salary is often reported as the median rather than the mean because a small number of very high earners would pull the mean significantly upward, making it unrepresentative of most workers.

Range, Sum and Other Statistics

The calculator also shows range, sum, count, minimum and maximum — here's what each one means:

Statistic	Definition	Example (data: 10, 20, 30)
Sum	Total of all values added together	10 + 20 + 30 = 60
Count	How many values are in the dataset	3 values
Range	Difference between the highest and lowest value	30 − 10 = 20
Minimum	The smallest value in the dataset	10
Maximum	The largest value in the dataset	30

FAQs

What is an average?

An average (or mean) is calculated by adding all values together and dividing by how many values there are. For example the average of 10, 20 and 30 is (10 + 20 + 30) ÷ 3 = 20.

What is the difference between mean, median and mode?

Mean is the arithmetic average of all values. Median is the middle value when sorted in order. Mode is the most frequently occurring value. They can all give different results for the same dataset.

Can I calculate averages with decimal numbers?

Yes — enter decimal values separated by commas and the calculator handles them correctly.

How many numbers can I enter?

As many as you need — separate values with commas, spaces or new lines and the calculator processes them all.

What is the range?

The range is the difference between the highest and lowest values in your dataset. It measures how spread out your data is.
