This is a web-based application to either calculate a sample size given a confidence level and confidence interval desired, or to evaluate the confidence interval for an existing sample.

This Sample Size Calculator is presented as a public service of Creative Research Systems. You can use it to determine how many people you need to interview in order to get results that reflect the target population as precisely as needed. You can also find the level of precision you have in an existing sample.
This will not work well for small populations. For small populations see Sampling from Small Populations.
