Average Calculator Formula & How It Works
Mean = ΣXᵢ / n | Median = middle value | Mode = most frequent value
- Mean (Arithmetic Average): sum ÷ count
- Median: middle value when sorted (or average of two middle values)
- Mode: value that appears most frequently
- Range: Maximum − Minimum
Mean is the most common 'average' but sensitive to outliers. Median is the middle value when sorted — more robust to outliers and better for skewed data (e.g., income). Mode is the most common value — useful for categorical data. Range measures spread.
