Stats: Enumerative and Analytic Studies (February 5, 2004). I received a question today via email about what statistics you can use when your sample equals the entire population. This issue also comes up when people ask about the use of the finite population correction factor. Both topics are controversial, and there is no clear consensus on what to do.
Stats: Web polls (July 30, 2001). Dear Professor Mean: I'm conducting a number of web-based polls on the web and would like to include a margin of error in my results. How do I do this?
Stats: Stratified random sample (August 23, 2000). Dear Professor Mean: What is a stratified random sample and why would I want to use one?
Stats: Quota stratified random sampling (January 28, 2000). Dear Professor Mean: I'm doing my thesis right now and I have to use the quota stratified random sampling. I do not know the exact meaning of this term.
