Understand statistics as inference about population parameters from random samples.
Decide whether a described sampling method produces a random sample from a population
Problem
Is this sampling method random: use random number generator on complete roster?
Big Picture
What this problem is really about
Classify the sampling method by its mechanism, not by whether a computer or roster happens to appear. A probability sample needs a defined frame and a chance-based rule that determines which units enter, without convenience, researcher preference, or self-enrollment driving participation. Its inference scope is the population represented by that frame.
