A quick and easy tool to calculate sample size!

Using this tool, you can calculate a known or unknown sample size for a survey.   Using the criteria of confidence level, width of confidence level, and expected value of attribute, the tool will automatically calculate the sample size of an unknown population.  For a known population, use the same criteria and put in the population size to have the sample size automatically calculated.  Excellent time saver to calculate the sample size for a survey.
