Average Calculator
Calculate the mean, median, mode, minimum, maximum, and range for a numeric dataset locally in your browser.
Enter numbers separated by commas, spaces, or new lines to calculate the mean, median, mode, minimum, maximum, and range. Calculations run locally in your browser; your values are not uploaded or stored.
Summarize a numeric dataset without uploading it.
Enter numbers separated by commas, spaces, or new lines to see the count, mean, median, mode, minimum, maximum, and range. The mean is the sum divided by the count, the median is the middle value of the sorted dataset, and the mode is the most frequent value. Everything runs locally in your browser, so your values are not uploaded or stored.
Frequently Asked Questions
Everything you need to know about this tool, how it works, and privacy.
What does the average calculator show?
Enter numbers separated by commas, spaces, or new lines. The calculator returns the count, mean, median, mode, minimum, maximum, and range for the dataset you entered.
How are the mean, median, and mode calculated?
The mean is the sum of all values divided by the count. The median is the middle value of the sorted dataset, or the average of the two middle values when the count is even. The mode is the most frequent value; when every value appears once, the result reports that there is no mode.
Which inputs are accepted?
Use finite numbers separated by commas, spaces, semicolons, or new lines. Decimal and negative values are accepted. The tool shows a clear error instead of a result when any entry is not a finite number or when no numbers are entered.
Do my dataset values stay private?
Yes. The calculation and copy action run locally in your browser. CodeASystem does not upload or store the values you enter.
