Random sample generator

How to use this calculator

Edit the seed 42, the data list, or sample size 3. Keeping the same seed repeats the sample; change it to request another draw.

Tap the math below to edit it and see the result. Once a result is ready, press Tab on a hardware keyboard to accept it. Outside a matrix, Return completes the line; the phone math keyboard has the same Return action.

What to know

Sampling is without replacement by position, so duplicate values in the input may still repeat in the result. These samples are not cryptographic randomness.

Mathlean combines visual mathematical input with computation and canvas tools. Results depend on the expression and available engine support; check important answers independently.
