Statistics Sample Generator

Used by developers, writers, and creators worldwide.

A statistics sample generator builds a random set of numbers and works out the summary statistics that describe it — mean, median, mode, range, and standard deviation. Students, teachers, and analysts constantly need practice data to demonstrate how these measures behave, but typing out a fresh sample and computing each statistic by hand is slow and error-prone. This tool draws a random sample within the range you choose and reports every key statistic instantly, all computed exactly from the sample shown. Set the sample size and the minimum and maximum, then copy the data and results. It is ideal for teaching statistics, building worked examples, testing spreadsheets, and seeing how averages and spread respond to different data. Because the full sample is listed alongside the numbers, you can verify every statistic yourself or reuse the data elsewhere.

FAQ

which statistics are calculated

The tool reports the mean, median, mode, minimum, maximum, range, and standard deviation. Together these describe both the centre of the data and how spread out it is, which covers the core measures taught in introductory statistics.

is the sample random each time

Yes. Every run draws a fresh random sample within your chosen range, so you can generate as many different practice sets as you like. The statistics are then computed exactly from whatever sample was drawn.

how is standard deviation worked out

It uses the population formula: the square root of the average squared distance of each value from the mean. This measures how far the numbers typically sit from the average, giving a sense of the spread.
