Detailed explanation-1: -Probability sampling refers to the selection of a sample from a population, when this selection is based on the principle of randomization, that is, random selection or chance. Probability sampling is more complex, more time-consuming and usually more costly than non-probability sampling.
Detailed explanation-2: -This statistical method used to select a sample from a population in such a way that each member of the population has a known, non-zero chance of being selected. The most critical requirement of probability sampling is that everyone in your population has a known and equal chance of getting selected.
Detailed explanation-3: -Random sampling is the truest form of probability sampling. This type of sampling guarantees that each member of a population has an equal chance of being included in the sample. This type of sampling is ideal for more controlled studies where human bias in the selection of the sample is intolerable.
