About the Statistics Calculator
Drop in any list of numbers — comma, space, or line-separated — and this tool computes the most common descriptive statistics: count, sum, mean, median, mode, min, max, range, variance, and standard deviation.
Variance and standard deviation are computed using the sample formula (dividing by n − 1), which is appropriate when the values are a sample from a larger population.
Frequently asked questions
What's the difference between mean, median, and mode?
The mean is the average. The median is the middle value when sorted (less affected by outliers). The mode is the most frequent value. Each tells you something different about the data's center.
Sample vs population standard deviation?
This calculator uses the sample formula (Bessel's correction, dividing by n − 1). This is the appropriate choice when your numbers represent a sample from a larger population, which is the most common case.
