About the Statistics Calculator
The Statistics Calculator computes the mean, median, mode, range, variance and standard deviation of a list of numbers. Paste your data separated by commas or spaces and the results update instantly.
The mean is the average, the median is the middle value when sorted, and the mode is the most frequent value. The range is the maximum minus the minimum. Variance and standard deviation describe the spread; this tool calculates the sample versions, dividing by n − 1, which is the usual choice when your data is a sample of a larger group. If your data is the complete population, the population standard deviation will be slightly smaller.

Tips and good to know
- The median is less affected by extreme values than the mean.
- If there is no repeated value, there is no mode.
- Check the units before comparing datasets.
