Sampling small populations

Sample Size Calculator

Need to survey a small population, but don't want to waste resources with a full census? Use this page to find a statistically relevant sample size. It allows you to calculate samples with 95% or 99% confidence (and a CI of your choice), based on the overall population.

I liked it so much,
I made an offline version in Excel.

It makes pretty graphs.
