Average Calculator – Calculate Mean, Median, Mode & Range

Enter your numbers separated by commas, spaces, or new lines, and select 'All' as the calculation type. The calculator instantly computes: mean (sum divided by count), median (middle value when sorted), mode (most frequent value), and range (maximum minus minimum). You can also toggle additional statistics for variance and standard deviation.

Use the median when your data contains extreme outliers that would skew the mean. For example, in income data where a few very high earners inflate the average, the median gives a better picture of what a typical person earns. The median is also preferred for housing prices, test scores with a few perfect results, or any dataset with a long tail on either end.

A weighted average multiplies each number by a weight that reflects its importance before averaging. To use it, toggle 'Use Weighted Average' and enter a weight for each number — for example, if a final grade is 40% exams and 60% coursework, the weights would be 0.4 and 0.6. The calculator multiplies each value by its weight, sums the results, and divides by the total of the weights.

Standard deviation measures how spread out your numbers are around the mean. A low standard deviation means most values cluster tightly near the average — like test scores in a class where everyone performed similarly. A high standard deviation means values are widely scattered — like incomes in a diverse economy. The calculator computes both population and sample standard deviation, which you can view by toggling 'Show Additional Statistics.'

If every number appears exactly once, there is no mode — and the calculator will report 'No mode.' If two or more values tie for the most frequent, the calculator reports all of them as multiple modes. This is normal and simply means your data doesn't cluster around any particular value.

Yes. Copy a column of numbers from Excel, Google Sheets, or any spreadsheet and paste directly into the input field. If your numbers are separated by line breaks, select 'New Line' as the delimiter. The calculator will parse the values and compute all statistics instantly.
