Detailed explanation-1: -A representative sample is one technique that can be used for obtaining insights and observations about a targeted population group. A representative sample is a small subset group that seeks to proportionally reflect specified characteristics exemplified in a target population.

Detailed explanation-2: -Random sampling, or probability sampling, is a sampling method that allows for the randomization of sample selection, i.e., each sample has the same probability as other samples to be selected to serve as a representation of an entire population.

Detailed explanation-3: -Cluster sampling Instead of sampling individuals from each subgroup, you randomly select entire subgroups. If it is practically possible, you might include every individual from each sampled cluster.

Detailed explanation-4: -Stratified random sample: The population is first split into groups. The overall sample consists of some members from every group. The members from each group are chosen randomly.

Detailed explanation-5: -Systematic sampling selects a random starting point from the population, then a sample is taken from regular fixed intervals of the population depending on its size.
