Simple Random Sample

In a Simple Random Sample each sample of size n is selected in such a way that every possible sample of size n has the same chance of being selected.

- from Elementary Statistics by Triola (2009).


In this example, members of a population are numbered and put into a hat. Tommy randomly picks two numbers from the hat. He then returns them and chooses again. Because of this, the population has an equal chance of being selected.
