Chapter 5. Sampling Distributions
... the data. We can better understand the uncertainty in the estimation, as well as the basic idea behind statistical inference, by introducing an important concept called the sampling distribution. A sample statistic (e.g., x̄,) can be conceptually viewed as a random variable, because before we collec ...

... again, as is done on page 47, that properly speaking the theory of probability is a mathematical theory, or rather a set of such theories, so contrived as to be applicable to a wide variety of physical situations, in physics, in the social sciences, in insurance, in games of chance, and in a large n ...

Unfortunately, non-trivial bias is expected in the process of galaxy formation as a consequence of the gravitational evolution of the initial Gaussian seeds in the non-linear regime (Fry & Gasta~naga, 1993), so the observed statistics of the galaxy distri ...
