Does the lottery method always give you a random sample? Explain.

Ans. Yes, If the lottery method is used correctly and without bias, it always produces a random sample. If the slips are properly prepared and drawn out one by one, each slip has an equal chance of being selected in the sample, the result will be a random sample. However, if the slips are not of identical size and identification of the names or numbers on the slips is possible, the selection will become biassed.
