Average Calculator
Determine the central tendency of dataset entries by calculating the arithmetic mean. Useful for academic grading, scientific experiment repeats, financial budgeting, and sensor observations.
Enter numbers separated by commas, spaces, or line breaks
Sum of all values divided by total count
How to Use This Calculator
- Paste or type your numbers separated by commas or spaces.
- Inspect the calculated mean, total sum, and sample size.
- Review the data range to understand sample dispersion.
Formula & Calculation Methodology
The arithmetic mean x̄ is calculated by taking the sum of all elements in the sample (Σx) and dividing by the total number of observations (n).
Worked Example

Frequently Asked Questions
How does the arithmetic mean differ from the median?↓
The mean sums all values and divides by count, making it sensitive to extreme outliers. The median is the physical middle value when sorted, resisting outlier distortions.
Can negative numbers be averaged?↓
Yes. Negative numbers are incorporated directly into the algebraic sum, lowering the resulting mean accordingly.
What formats can I use to paste numbers?↓
The parser accepts commas, spaces, tabs, and newlines as valid delimiters between numbers.
What is a limitation of the arithmetic average?↓
A single severe outlier (e.g. one billionaire in a room of workers) heavily skews the mean, making it unrepresentative of the typical experience.
