Paste your numbers and get the full picture — count, mean, median, mode, range, variance, standard deviation, quartiles and IQR (both sample and population). Switch to Regression to fit a line of best fit to x,y pairs. Everything runs in your browser.

Your statistics appear here.

All calculations run on your device. “Sample” statistics divide by n−1 (use these for a sample of a larger population); “population” statistics divide by n. Quartiles use the median-of-halves (Tukey) method, so they can differ slightly from other conventions. Regression is ordinary least squares; r is the correlation coefficient and r² the coefficient of determination. Nothing is uploaded.
