Yes, it is discrete, but the underlying distribution is Gaussian. Just got the following from a college:
Var(mean of finite population) = ((N - n)/(N - 1)) * var(population) / n This should be it... Greetings, Roy -----Original Message----- From: Liaw, Andy [mailto:[EMAIL PROTECTED] Sent: Wednesday, March 23, 2005 2:17 PM To: Roy Werkman; [email protected] Subject: RE: [R] Question on statistics If the sample is drawn with replacement from the finite population, then the usual formula applies (assuming iid samples); i.e., var(sample mean) = var(population) / n. There's some problem in your description: A finite population, I believe, is necessarily discrete (since there are only N possible values), so it can not be Gaussian (i.e., normal).
