Statistics
Mean, Median, Mode Calculator
Find any of the three classic measures of central tendency — mean, median, or mode — from a comma-separated list of numbers. Use the mean for symmetric data, the median for skewed data, and the mode for the most common value.
Fill in the required fields to see your result.
Statistics
Standard Deviation Calculator
Compute the sample standard deviation directly from three summary statistics — sample size n, the sum of values Σx, and the sum of squared values Σx². This is the spread metric used in virtually every empirical study, quality-control chart, and risk model.
