About the Average Calculator

What is an Average?

An average is a single number that represents the central tendency of a dataset. Different types of averages are useful in different contexts: arithmetic for typical values, geometric for growth rates, and harmonic for rates and ratios.

How to Use

Enter your dataset as comma-separated numbers, select the average type, and click Calculate. The tool returns the selected average along with supporting statistics.

What is the difference between arithmetic and geometric mean?

Arithmetic mean is the sum divided by count. Geometric mean is the nth root of the product of values. Geometric mean is better for multiplicative processes like investment returns.

When should I use harmonic mean?

Use harmonic mean when averaging rates or ratios, such as average speed over equal distances or parallel resistance in electronics.

Can I use negative numbers?

Arithmetic mean supports negative numbers. Geometric and harmonic means require all positive numbers to produce real, meaningful results.
