Ex-Sample

Ex-Sample computes minimum required sample size for over 60 different statistical analyses using either power analysis or traditional procedures at the user's discretion. It also computes the maximum possible sample size given resources such as time, money and personnel; and it adjusts for completion factors such as response rates, contamination rates, and exclusion rates. Ex-Sample compares the required sample size to maximum feasible size and uses artificial intelligence reasoning to suggest ways to reduce the required sample size or increase the feasible sample size.
