Question

What is the difference between selecting a member at random from a finite population and taking a simple random sample of size​ 1? choose the correct answer below.
a. a random member cannot be selected from a finite population.
b. the simple random sample is repeatable while the selection from the finite population is not.
c. each member of the finite population does not have the same probability of being selected.
d. there is no difference?

Answer 1

What is the difference between selecting a member at random from a finite population and taking a simple random sample of size​ 1?

Solution: The correct option is d. There is no difference

Explanation:

Random sampling: In random sampling, each and every unit of the population has an equal chance of included in the sample.

Simple random sampling: In simple random sampling, also every unit of the population has an equal chance being included in the sample.

In the given situation, the selecting a member randomly from a finite population will be same as using a simple random sampling to select sample of size 1. Therefore, there is no difference between the two.
