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: -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-3: -Probability sampling means that every member of the population has a chance of being selected. It is mainly used in quantitative research. If you want to produce results that are representative of the whole population, probability sampling techniques are the most valid choice.
