Random assignment to conditions

Balanced block randomisation of participants to conditions, reproducible from a seed you can report.

Or a single number, e.g. 60, to number them 1 to 60.

Names separated by commas.

Leave empty and one is chosen and shown, so the same list can be produced again.

Nothing you enter is stored or sent anywhere. The calculation runs for this request and is then gone.

Before you use this

Fill in the form and the result appears here, along with every intermediate value and a note on what the number does not mean.

These calculators run on the server with a plain form post, so they work with JavaScript disabled and nothing is sent to a third party.
