**Probability sampling** (a term due to Deming, [Deming]) is a **sampling** porcess that utilizes some form of random selection. In **probability sampling**, each unit is drawn with known **probability**, [Yamane, p3] or has a nonzero chance of being selected in the sample. [Raj, p10] Such samples are usually selected with the help of random numbers.
