Average Calculator

Paste or type a list of numbers and this calculator returns the full picture at once: mean, median, mode, sum, count, minimum, maximum, and range. It saves you from juggling several formulas when reviewing grades, prices, survey results, or measurements. Separate values with commas, spaces, or new lines and the stats update together.

How to use the Average Calculator

1. Enter your numbers separated by commas, spaces, or line breaks.
2. Let the calculator parse the list and count the valid values.
3. Review the mean, median, and mode for the central values.
4. Check the sum, count, min, max, and range for the spread of your data.

Frequently asked questions

What is the difference between mean, median, and mode?

The mean is the sum divided by how many values there are, the median is the middle value when sorted, and the mode is the value that appears most often. For 2, 2, 3, 7, the mean is 3.5, the median is 2.5, and the mode is 2.

How is the median found when there is an even number of values?

Sort the values and average the two middle ones. For 4, 8, 10, 20, the two middle numbers are 8 and 10, so the median is 9.

What does range tell me?

Range is the maximum value minus the minimum value, showing how spread out the data is. For 5, 12, 30, the range is 30 minus 5, which is 25.

Can a data set have more than one mode?

Yes. If two or more values tie for the most occurrences, the set is multimodal, and if every value appears once there is no mode at all.
