Question

A simple random sample is always preferred because it obtains the same information as other sampling plans but requires a smaller sample size: false why?

Answer 1

The answer is false. A simple random sample is a subset of a factual populace in which every individual from the subset has an equivalent likelihood of being picked. A case of a straightforward arbitrary specimen would be the names of 25 workers being picked out of a cap from an organization of 250 representatives.
