Draw a fair random sample
This tool draws a simple random sample from a population you provide. Paste a list of names or IDs, or sample from numbered rows by setting 1 to N, then choose your sample size. Every member has the same chance of being picked, which is what makes the sample fair.
With and without replacement
A sample without replacement takes each item at most once, the normal way to choose people for a survey or rows for an audit. A sample with replacement can pick the same item more than once, which is what resampling methods such as the bootstrap need. Switch between the two with the option.
Fair and private
The sample is drawn by shuffling with the browser cryptographic random source, so no member is favoured. Your population never leaves the device, which makes the tool safe for lists you would not want to upload.

Frequently asked questions
What is a random sample
A subset drawn from a larger population so that every member has an equal chance of being chosen, which lets you study the whole from a fair slice.
With or without replacement
Without replacement, each item can be picked once, the usual choice for a survey sample. With replacement, an item can be drawn more than once, which suits bootstrap style resampling.
Can I sample from my own list
Yes. Paste your population one item per line, or leave it empty and set 1 to N to sample from numbered rows.
How large can it be
Populations up to one hundred thousand and samples up to ten thousand, which covers most practical sampling.
Is it free
Yes, free and with no sign up.
