Statistics Calculator: Mean, Median, Mode & Standard Deviation
This calculator gives the core descriptive statistics for a numerical dataset. It is useful for students, exam scores, survey data, research work, business analysis, and everyday number crunching.
MeanSum รท number of values
MedianMiddle value after sorting
ModeMost frequent value(s)
Standard deviationHow spread out the values are
Population vs sample standard deviation
Population SD divides by N and is appropriate when the dataset contains the full population you are analysing. Sample SD divides by Nโ1 and is commonly used when the dataset is a sample used to estimate a larger population.
How to use this calculator
Paste the values into the box, choose population or sample standard deviation, and press Calculate Statistics. You can separate values with commas, spaces, or line breaks.
Quick example
For 10, 15, 20, 25, 30, 15, 20, the mean is 19.29, the median is 20, the modes are 15 and 20, and the range is 20.
Frequently Asked Questions
When should I use median instead of mean? +
Median is often more representative when your data contains strong outliers or is skewed. Income, house prices, and some response-time datasets are common examples.
Can a dataset have more than one mode? +
Yes. If two or more values share the highest frequency, the dataset is multimodal and the calculator reports all tied modes.
What happens when every value is unique?
There is no repeated value, so the calculator reports no meaningful mode.
