How it works
Enter your data points separated by commas, spaces, or line breaks. The calculator computes descriptive statistics including measures of central tendency (mean, median, mode), spread (standard deviation, variance, range, IQR), and position (quartiles, min, max). Both population and sample standard deviations are shown.
