Statistics can be summarizes as one thing n -> N. Does ‘little n’ represent ‘big N’. In other words, does the sample generalize to the population. Statistics means something like “description of the state”. It was born out of census samples where larger population samples had to be estimated. “n” could be a handful of fish in a “N” lake. “n” could also be the parameter estimated in a linear regression with the sample of data collected while “N” is the true parameter of the relationship if we had all the data. Point estimation is about finding the needle in the haystack, but much more often statistics is about finding the haystack given the needle. One tool statistics uses to get to the haystack is probability.

In statistics there are latin letters and greek letters. When you see a symbol denoted as a greek letter then that is a population parameter. When you see a latin letter that is a sample estimate. It could be Frequentist, Bayesian, Likelihoodist, Fiducial, Empirical Bayes, etc. Theoretical population greeks or sample calculated latins.
