What Is the Statistics Calculator?
The Statistics Calculator computes descriptive statistics for any list of numbers: count, sum, mean, median, mode, minimum, maximum, range, and both sample and population variance and standard deviation. Paste your data separated by commas or spaces and get every summary statistic at once.
How It Works
Paste or type your numbers separated by commas or spaces. All statistics recalculate instantly as you edit.
When to Use It
For students, researchers, analysts and teachers summarizing a data set, checking homework, or getting quick descriptive stats without a spreadsheet.
Frequently Asked Questions
- Sample vs population standard deviation?
- Sample SD divides by n−1 (use when your data is a sample of a larger group); population SD divides by n (use when you have the whole population). Both are shown.
- How is mode handled?
- It lists every value tied for the highest frequency, or shows none if all values are unique.
