Supports decimals and negative numbers

Must have the same number of weights as data values for weighted mean

How it works: Enter your data values to calculate arithmetic mean, median, geometric mean, and harmonic mean. Optionally add weights for weighted mean. The calculator also shows count, sum, and range statistics.

What is Average Calculator?

Enter a list of numbers separated by commas or spaces to calculate the mean (arithmetic average), median (middle value), mode (most frequent value), and range (difference between max and min). The calculator also shows the count of numbers, sum, and sorted list. All processing happens in your browser.

The mean is calculated by summing all values and dividing by the count. The median is the middle value of the sorted list, or the average of the two middle values for even-length lists. The mode is the value appearing most frequently, with support for multiple modes. The range is the maximum value minus the minimum value.

Key Features
Calculates mean, median, mode, and range simultaneously
Handles large datasets with hundreds of numbers
Detects and displays multiple modes
Shows the sorted number list for verification
Accepts comma-separated or space-separated input
Displays total count and sum of values
Common Use Cases
When and why you might need this tool

Homework and exams

Students can quickly verify their average calculations for math and statistics assignments.

Grade tracking

Teachers and students can calculate cumulative averages across multiple test scores or assignments.

Data analysis

Analysts can compute basic descriptive statistics for datasets in spreadsheets or reports.

Survey results

Researchers can find the central tendency and spread of survey response data.

How to Use This Tool
Step-by-step guide to get the best results
1

Enter your numbers

Type or paste your numbers into the input field, separated by commas or spaces.

2

Click calculate

The calculator processes your input and computes all four measures at once.

3

Review the results

See the mean, median, mode, and range along with the sorted list and total count.

Pro Tips
1

Use the median instead of the mean when your data has extreme outliers

2

If there is no repeating number, the calculator will indicate there is no mode

3

Paste numbers directly from a spreadsheet by copying a column and pasting into the input

4

The range gives a quick sense of how spread out your data is

Frequently Asked Questions
What is the difference between mean and median?

The mean is the arithmetic average found by dividing the sum by the count. The median is the middle value when all numbers are sorted. The mean is sensitive to outliers while the median is not.

Can there be more than one mode?

Yes, a dataset can have multiple modes if two or more values appear with the same highest frequency. The calculator will display all modes in this case.

How does the calculator handle even-numbered lists for median?

When the list has an even number of values, the calculator takes the average of the two middle values after sorting. This is the standard statistical approach.

What happens if I enter non-numeric values?

The calculator filters out any non-numeric entries and processes only valid numbers. You will see a count of valid entries so you can verify your input.

Is there a limit to how many numbers I can enter?

The calculator can handle hundreds of numbers without performance issues. Very large datasets in the thousands may take a brief moment to process.
