Use this average calculator to work out the mean, median, mode, range and standard deviation from a set of numbers. It is useful for school work, business reports, sports stats, survey results and quick everyday checks.
For the mean average, use: sum of values divided by number of values. For example, 4, 8 and 12 have a mean of 8 because 24 divided by 3 equals 8.
Median and mode are useful when one unusually high or low number would make the mean misleading.
Students can check marks, analysts can summarise data, and households can compare spending. If your numbers have different importance, use a weighted average instead of a simple average.
For more number tools, try the percentage calculator, GPA calculator, finance calculator or unit converter.
Add the numbers together, then divide by how many numbers you added. This gives the mean average.
In everyday use, average usually means the mean. In maths, average can also refer to median or mode depending on the question.
Use the median when your data has extreme values that would pull the mean too high or too low.
