Why use this calculator
Mean, median, and mode are the three measures of central tendency — fundamental statistics concepts used in data analysis, research, and everyday decision-making.
How to use it
Enter up to 5 values to calculate all three measures of central tendency plus range.
The formula
Mean = Sum / Count. Median = middle value when sorted. Mode = most frequent value. Range = Max - Min.
Worked examples
Data: 5, 10, 10, 15, 20
Mean = 12, Median = 10, Mode = 10, Range = 15
When people use it
- Data analysis
- Academic research
- Business analytics
- Quality control
Tips
- Mean is sensitive to outliers
- Median is more robust for skewed data
- Mode is most useful for categorical data
Questions people ask
- When should I use median instead of mean?
- Use median when your data has outliers or is skewed. For example, median income is more representative than mean income because a few very high earners skew the mean upward.
