How to use this tool

  1. Enter population size, infinite-population sample requirement.
  2. Use the displayed units and confirm the model assumptions.
  3. Calculate and compare the outputs against your input scenario.

Try this example

{
  "N": 1000,
  "n0": 384.16
}

Accuracy and scope

Simple random sampling without replacement from a known finite population; does not account for nonresponse or clustering.
