StatisticsMeanMedianStandard DeviationVariance
A comprehensive statistics calculator that computes mean, median, mode, standard deviation, variance, quartiles, IQR and more from any dataset you paste in.

Key Features

Central Tendency
Calculates mean (average), median (middle value), and mode (most frequent value — handles multi-modal data).
Spread Measures
Population and sample variance, population and sample standard deviation, and range.
Quartiles & IQR
Q1, Q2, Q3 using the inclusive method, plus interquartile range (IQR) for outlier detection.
Box Plot
Generates an SVG box-and-whisker plot for a visual summary of the distribution.
Sample vs Population Toggle
Switch between sample (÷ n−1) and population (÷ n) formulas for variance and standard deviation.
Sorted Data
Shows the dataset in sorted order for easy verification.

How to Use
