Descriptive Statistics Calculator

Paste a list of numbers — get the count, sum, mean, median, mode, min, max, range, variance and standard deviation (population & sample), the quartiles Q1/Q3, the IQR, a box plot, and full step-by-step working.

Mean:  x̄ = (Σ x) / n

Enter at least one number. Separate values with commas, spaces, or new lines. Decimals and negatives are fine. Quartiles use the Tukey (median-of-halves) method.
