Average Calculator – Mean, Median, Mode & Range
The Average Calculator computes the four most important statistical measures in one click. Whether you're a student, researcher, or professional — this tool handles it all instantly.
Mean (Arithmetic Average)
The mean is the most common average. Add all numbers, divide by the count. Mean = Sum ÷ Count. The mean is sensitive to extreme outliers.
Median (Middle Value)
The median is the middle value when sorted. For even counts, it's the average of the two middle values. Less affected by outliers than the mean.
Mode (Most Frequent)
The mode is the value appearing most often. A dataset can have no mode (all values unique), one mode, or multiple modes.
Range (Spread)
The range shows data spread. Range = Maximum − Minimum. A large range indicates high variability.
When to Use Each Measure
- Mean: Best for symmetric data (e.g., average test scores).
- Median: Better for skewed data (e.g., median household income).
- Mode: Best for categorical data (e.g., most popular shoe size).
- Range: Quick variability check (e.g., weekly temperature range).
