Work out the average of any numbers
Type or paste a list of numbers, separated by commas, spaces or new lines, and this tool returns the arithmetic mean along with the running total and how many values you entered. The average is simply the sum divided by the count, the figure most people mean by the word average. It handles decimals and negative values, and recalculates the moment you change the list. Everything stays in your browser.
Where the mean is used
Grades, test scores, monthly spending and sensor readings are all commonly summarised by their mean, which makes it the everyday measure of a typical value.
