Which of the following is the best description of a simple random sample of size n from a population of size N.

A) Any method of sampling in which individuals are selected in a completely haphazard fashion.

B) Any method of sampling in which every group of individuals of size n is equally likely to be selected.

C) Any method of sampling in which every individual is equally likely to be selected.

D) Any method of sampling in which each individual has a probability of n/N of being selected.

The best description of a simple random sample is given by:

C) Any method of sampling in which every individual is equally likely to be selected.

Explanation: A simple random sampling is a way of sampling where every individual is equally likely to be selected. In other words if there are n individuals, the probability of each individual getting selected is 1/n.
