INFERENTIAL STATISTICS
... Interestingly, it is the absolute size of the sample rather than the ratio of sample size to population size, that most affects sampling error. If you don’t have a population standard error, you rely on a best estimate—the standard deviation of the sample. THE LOGIC OF HYPOTHESIS TESTING—AKA Six ste ...
