I'm reading an Econometrics textbook and it talks about "Simple Random Samples" and "IID draws" (Independent, Identicaly Distributed variables).
While it defines the two seperately, it also seems to imply that they are the same thing.
From what I understand, a simple random sample is where n objects are selected from a population at random. While an IID draw is where n objects are randomly selected from a population of independent and identically distributed random variables.
(by randomly selected I mean that each random variable is equally likely to be selected)
So: Does is a 'simple random sample' the same thing as an 'iid draw' or are they not necessarily the same thing?
