Frequently Asked Questions
What is the difference between mean and median?
Mean is the sum divided by count — sensitive to outliers. Median is the middle value when sorted — better for skewed data like income.
How is mode calculated with ties?
If multiple values share the highest frequency, all tied values are listed as modes. If every value appears once, there is no mode.
Can I enter decimal numbers?
Yes. Integers and decimals work. The tool parses any valid numeric input in your list.
What is range?
Range = maximum − minimum. It shows how spread out your data is without measuring variance.
Is this average calculator free?
Yes. Unlimited lists with no signup; numbers stay in your browser.
