... n = the number of test subjects you are discussing. Every time you speak of the entire group or ‘cohort’ include how many there were [n=12]. If you are talking about test subjects in a category [or cohort] include how many were in that category [n= 3] This gets important when you think about a state ...

1 N SAMPLING DISTRIBUTION
... Therefore, it is important to recognize that inferential statistics and hypothesis testing in their most common forms are based on sampling distributions of statistics not on the actual data at hand. Moreover, because the referent distribution is the sampling distribution of the test statistic, the ...
