Calculate average, median, mode, range, and standard deviation
Average Calculator helps analyze pasted score lists, sales numbers, survey ratings, temperatures, and other numeric datasets. It recognizes commas, whitespace, line breaks, and thousands separators, then calculates summary statistics directly in your browser.
Useful For
- Find representative values for scores or survey ratings
- Check average and range for sales or cost lists
- Use the distribution bars and standard deviation to review spread
Good To Know
Custom numbers are not included in shared links. Split very large datasets into smaller batches to keep browser-side processing smooth.
Result Check
Try an example first to understand the input flow. Before submitting, sharing, or copying important output, compare the result with the original source once more.
How It Works
Inputs are calculated or converted in the browser whenever possible. Compare important results with the original source before using them. Reviewed on Jun 30, 2026.
Average calculation checks
Input numbers
- Separate numbers with commas, spaces, or line breaks
- Check thousands separators and decimals are parsed as intended
Statistics
- Separate mean, median, mode, and range because they answer different questions
- When outliers exist, compare median alongside mean
Interpretation
- Confirm whether sample or population standard deviation is expected
- Recheck count against source data for grades, sales, or experiment values
Yes. It calculates average, median, mode, range, and standard deviation from a numeric list.
The parser supports commas, whitespace, line breaks, and thousands separators where possible.
Processing runs in the browser, so very large datasets can be slow. Split large lists into smaller batches when needed.
