Random Sample Picker

The fairest sample is a random one. Number your list (customers, invoices, houses on a street) or paste it, choose a sample size, and get a selection in which every item had the same chance.

Enter how many items there are and how many to pick, then press Pick a sample.
From the book, Chapter 9. A random sample fixes chance, not bias: it only represents the list you drew it from. If the list leaves people out, so will the sample. Picks are drawn without replacement using your browser’s cryptographic random numbers where available.
