Average Calculator
Calculate mean, median, mode, and range of numbers
What Is an Average Calculator?
An average calculator computes the central tendency of a set of numbers. It calculates the mean (average), median (middle value), mode (most frequent value), and range (difference between highest and lowest). These statistics help understand data distribution and patterns.

Median: 4.5
Mode: 4 (appears 3 times)
Range: 7 (2 to 9)
Understanding the Statistics
Mean (Average)
Sum of all numbers divided by the count. The most common measure of central tendency.
Median
The middle value when numbers are sorted. Less affected by outliers than the mean.
Mode
The most frequent value. Useful for categorical data. A dataset can have multiple modes.
Range
The difference between the highest and lowest values. Shows data spread.
FAQs
What is the difference between mean and average?
They're the same thing! "Mean" is the mathematical term for what most people call "average."
When should I use median instead of mean?
Use median when your data has outliers or is skewed (e.g., income data, house prices).
Can a dataset have multiple modes?
Yes! If two or more values appear equally often, the dataset is multimodal.
