Average Calculator

Average (arithmetic mean) is the sum of all values divided by the count of values. Median is the middle value when numbers are sorted. Mode is the most frequently occurring value. Range is the difference between max and min.

To find the average (mean) of numbers: add all numbers together and divide by how many numbers there are. Example: (4 + 8 + 12 + 16) ÷ 4 = 40 ÷ 4 = 10.

Key Features

• Calculates mean (arithmetic average), median, mode, and range.
• Accepts any number of values — paste from spreadsheets or type manually.
• Handles negative numbers and decimals.
• Shows count, sum, min, and max alongside the averages.
• Works entirely in your browser — no data sent anywhere.

How to Use the Tool

1. Paste or type your list of numbers into the input field, separated by commas or new lines.
2. The mean, median, mode, sum, count, range, min, and max are computed instantly.
3. Click 'Copy Result' to copy the statistics summary.

Core Benefits

• Faster than doing it by hand, especially for large datasets.
• Useful for students checking homework calculations.
• Helps with data analysis — understand the central tendency of a dataset instantly.

Common Use Cases

• Calculating the average score of multiple exam results.
• Finding the mean monthly sales figure from a list of values.
• Determining the median salary from a dataset for pay negotiation.
• Data analysis: checking the mode (most common value) in survey responses.
• Statistics homework and coursework calculations.

Pro Tips

• Mean is sensitive to outliers. If one value is very extreme, median is a better measure of center.
• If all numbers appear only once, there is no mode (or all values are modes).
