Statistics, Instantly

Paste in a list of numbers for the mean, median, mode, quartiles and standard deviation — with the working — plus a histogram. Switch to x, y pairs for a scatter plot, line of best fit and correlation.

Tip: you can paste a column straight from a spreadsheet.

Examples:

Which average should I use?

Mean uses every value, so it is best for symmetric data — but a single outlier can drag it a long way.

Median is the middle value. It ignores extremes, which makes it the better choice for skewed data like incomes or house prices.

Standard deviation measures the typical distance from the mean. Roughly 68% of normally distributed data lies within one SD.
