Bias in Estimation and Hypothesis Testing of Correlation
... decreases as sample size increases and that it is zero when the population correlation is zero. For n = 10 or n = 20, it is of the order .01 or .02 when the correlation is about .20 or .30, and about .03 when the correlation is about .50 or .60. Differentiating ρ (1 − ρ 2 ) / 2n with respect to ρ, s ...

Sampling Distributions
... Approximated with simulation techniques Derived using mathematical theorems The Central Limit Theorem is one such theorem. Central Limit Theorem: If random samples of n observations are drawn from a nonnormal population with finite m and standard deviation s , then, when n is large, the sampling ...

In practice, it is too expensive and time consuming to obtain every MBA salary, which means in practice, that we cannot determine µ exactly. The important point to understand from this discussion is that the population mean µ is ...
