Paste a list of numbers into the box and this average calculator works out the mean, median and mode along with the sum, count, range and a sorted copy of your list. It runs in your browser, accepts commas, spaces or line breaks as separators, and shows how the median was found.
The mean is the figure most people picture. Every value is added up and the total is split evenly across the count, so each entry pulls the result toward itself.
The median is the middle of the sorted list. Half the values sit below it and half sit above it, and one very large or very small entry cannot drag it around the way it drags the mean.
The mode is the value that turns up most often. A list can have one mode, several modes, or no mode at all when every value appears the same number of times.
The range runs from the smallest value to the largest, and the gap between them hints at how spread out the list is. A tight range means the values huddle together.
Geometric and harmonic means appear only when the list allows them. The geometric mean suits growth rates, where values build on each other over time. The harmonic mean suits rates, such as an average speed worked out over set distances.
The warning at the top of the tool is the one that saves the most grief: write 1000, not 1,000, because a comma inside a number is read as a separator and quietly turns one value into two.
Entries that are not numbers are named in the result so you can spot and fix them. Nothing is dropped in silence, and a stray word in a pasted list will not skew the answer without you knowing.
The mean is pulled by outliers. One huge salary in a list of wages lifts the mean well past what most people in the list earn, and for skewed lists like incomes the median is usually the fairer middle.
Everything runs on your own device. Your numbers are never uploaded or stored, there is no sign-up, and there are no usage caps, so long lists and repeat checks cost nothing.
The mean shares the total evenly across every value, while the median is the middle value of the sorted list. Outliers move the mean a lot and the median hardly at all, which is why the median often describes a skewed list better.
Because commas separate entries here. A comma inside a number splits it into two entries, so 1,000 is read as 1 and 0, and both the count and every average come out wrong.
The mode is the value that appears most often in your list. It helps when you want the most common outcome, such as the shoe size a shop sells most, rather than a middle figure.
The tool names the entry that failed so you can find and fix it. Nothing is skipped quietly, since a dropped value would change the count and bend every average that follows.
Use it for growth rates and other figures that build on each other over time, such as yearly returns or population growth. For plain lists of separate values, the ordinary mean is the right pick.
