Mean Median Mode Range Calculator

This calculator finds the four headline measures of a data set, the mean, median, mode and range, along with the count, sum and the smallest and largest values, all from a single list of numbers. These are the everyday tools of descriptive statistics, and each tells you something different about your data. The mean is the average, found by adding the values and dividing by how many there are, and it is the most familiar measure of the centre, though it can be pulled around by very high or very low values. The median is the middle value once the numbers are sorted, which makes it a more robust measure of the centre for skewed data such as house prices or incomes, where a few large figures would distort the mean. The mode is the value that appears most often, useful for spotting the most common result, and a data set can have more than one mode or none at all. The range, the gap between the largest and smallest, is the simplest measure of spread. You enter your numbers separated by commas, spaces or new lines, and the calculator works out every measure at once. It is ideal for schoolwork, marking, surveys and quick analysis.
