... which the procedures can be applied. For some basic analyses of contingency tables, it is unnecessary to use large-sample approximations to sampling distributions when their adequacy is in doubt. This article surveys the current theoretical and computational developments of exact methods for conting ...

Sampling Distribution for the mean
... Example: (Analogy from Cartoon Guide to Statistics) Consider an archer shooting at a target. Suppose she hits the bulls eye (a 10 cm radius) 95% of the time. In other words, she misses the bulls eye one out of 20 arrows. Sitting behind the target is another person who can't see the bull's eye. The a ...
