You mean drawing samples (random sampling) from the same population? – smanoos Jan 04 '12 at 17:26

I am sure you are referring to random sampling.
The random variables $X_1,X_2,...X_n$ are called a random sample of size $n$ from the population with pdf $f(x)$ if $X_1,X_2,...X_n$ are mutually independent and the marginal pdf of each of them is exactly $f(x)$.
