• sampling distribution of a sample proportion ρ̂

In an SRS of size n from any population with mean µ and finite standard deviation σ, when n is sufficiently large, the sampling distribution of the sample mean x is approximately Normal.

• central limit theorem (CLT)

• standard curve theorem (sct)

• parameter

The fact that different random samples of the same size from the same population produce different estimates.
