## About Mean Median Mode Calculator

The online Mean Median Mode Calculator is used to calculate the count, sum, mean, median, mode and range of a set of numbers.

## Mean

The mean is the arithmetic average of a data set, computed by adding up a collection of numbers and dividing by their count.

## Median

In probability theory and statistics, the median is the middle data value of a set of values when the data have been arranged into order. If there is an even number of data, then there is no single middle value; the median is then usually defined to be the mean of the two middle values.

## Mode

In statistics, the mode is the most frequently occuring value in a data set. The mode is not necessarily unique, since the same maximum frequency may be attained at different values.

## Range

The range of a set of numbers is the difference between the greatest value and the lowest value. It describes how spread out the data is.
