Average Calculator FAQ

What is an average calculator?

An average calculator adds a set of numbers and divides the total by the number of values. It can also show median, mode, and range to describe the data set more fully.

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

Mean is the sum divided by the count, median is the middle value after sorting, and mode is the value that appears most often.

Can a data set have more than one mode?

Yes. If two or more values tie for the highest repeat count, the data set is multimodal and this calculator lists every mode.

Can I use decimals and negative numbers?

Yes. Enter whole numbers, decimals, or negative values separated by commas, spaces, semicolons, or new lines.

Which average should I use for classroom data?

Mean is useful for balanced data, while median is often more representative when one unusually high or low value would pull the mean away from most scores.
