How the average is calculated
Add up all the numbers and divide by how many there are. For 7.5, 8, 6.5, 9 and 8: (7.5 + 8 + 6.5 + 9 + 8) ÷ 5 = 39 ÷ 5 = 7.8. This is the arithmetic mean, usually just called the average.
Entering numbers
Separate the numbers with a semicolon, a space or a new line, so you can paste a column from a spreadsheet. Commas work as separators too, as long as you don't also use decimal commas.
Average, median or mode?
The mean uses every value, so one outlier can pull it far away. The median is the middle value and isn't bothered by outliers. The mode is the value that occurs most often. For quartiles and a box plot, use the median calculator; for spread, the standard deviation calculator.
