Explanation:
Detailed explanation-1: -There are four primary, random (probability) sampling methods – simple random sampling, systematic sampling, stratified sampling, and cluster sampling.
Detailed explanation-2: -The Formula of Random Sampling Here P is a probability, n is the sample size, and N represents the population. Now if one cancels 1-(N-n/n), it will provide P = n/N. Moreover, the chance of a sample getting selected more than once is needed: P = 1-(1-(1/N)) n.
Detailed explanation-3: -Undercoverage bias occurs when some members of your population are not represented in the sample. It is common in convenience sampling, where you recruit a sample that’s easy to obtain.
