Average Calculator

The Average Calculator computes six key statistics from any list of numbers: mean, median, mode, range, sum, and count. Enter your numbers separated by commas, spaces, or new lines — the calculator handles the rest instantly.

The three types of "average" each describe the data differently:

• Mean — The arithmetic average. Add all numbers and divide by the count. Most commonly used but sensitive to outliers.
• Median — The middle value when the numbers are sorted. For an even count, it's the average of the two middle values. Robust against outliers.
• Mode — The value that appears most often. Useful for categorical data or when you want to know the most common result.

The range (max − min) gives a quick sense of how spread out the data is. For a deeper measure of spread, use standard deviation (a separate calculation). The range is a good first indicator when comparing data sets.

Example

Find the mean, median and mode of: 4, 8, 6, 4, 9, 3, 4, 7.

Mean: (4+8+6+4+9+3+4+7) / 8 = 45 / 8 = 5.625

Median: Sort the values: 3, 4, 4, 4, 6, 7, 8, 9. Two middle values are 4 and 6. Median = (4+6)/2 = 5.

Mode: 4 appears 3 times — more than any other value. Mode = 4.

Range: 9 − 3 = 6. Sum = 45. Count = 8.
