The average calculator computes the mean, median, mode, minimum, maximum, range, sum, and the count of values, duplicates, and unique values from an entered list of numbers directly in your browser, all at once. The list can be entered via line breaks, semicolons, tabs, or a comma-separated list.
Typical searches include calculate average, calculate mean, and find median. Calculation runs locally in the browser. Ambiguous or invalid values are not guessed; for outliers, also check the median and range, since they can shift the mean significantly.
Typical use cases
Get multiple metrics from a data list at once
Paste a list of measurements or grades to see the mean, median, mode, and range at once, without separate calculations.
Spot duplicates and outliers in a list
Use the display of duplicates and unique values to quickly check whether a data list contains recurring values or outliers.
Tips for better results
Also check the median with outliers
A single extremely high or low value can shift the mean significantly — the median is often more informative in such cases.
Use the input format flexibly
Values can be pasted via line breaks, semicolons, tabs, or as a comma list — convenient when copying from spreadsheets.
