Detailed explanation-1: -Social researchers speak more commonly of probability sampling, meaning that every member of a population being sampled has a known, non-zero chance of being selected into the sample. Usually, the probability of selection is also less than 100%, so random selection methods become involved.

Detailed explanation-2: -Stratified random sampling: Each unit in the population is identified, and each unit has a known, non-zero chance of being in the sample. This is used when the researcher knows that the population has sub-groups (strata) that are of interest.

Detailed explanation-3: -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.

Detailed explanation-4: -Non-probability sampling is a method of selecting units from a population using a subjective (i.e. non-random) method. Since non-probability sampling does not require a complete survey frame, it is a fast, easy and inexpensive way of obtaining data.

Detailed explanation-5: -Non-probability sampling is a method of selecting samples for the study when all the samples are not having equal chances to get selected for the study.
