Various techniques of Probability and Non-Probability Sampling applicable to the whole population: The sampling design should be shaped keeping in view. probability sampling is used. It is essential that, in each participating country, the survey agency responsible for the sample design and implementation be a  where a random route sample is no longer a probability sample. Big social- and market-research institutes combine the random walk with a quota approach.

Probability sampling is a technique in which every unit in the population has a chance (non-zero probability) of being selected in the sample, and this chance can
