A probability sampling method is any method of sampling that utilizes some form of random selectionin order to have a random selection method, you must set up some process or procedure that assures that the different units in your population have equal probabilities of being chosen.
Another non-probability method, quota sampling also identifies strata like stratified sampling, but it also uses a convenience sampling approach as the researcher will be the one to choose the necessary number of participants per stratum. What are the main types of sampling and how is each done simple random sampling: a simple random sample (srs) of size n is produced by a scheme which ensures that each subgroup of the population of size n has an equal probability of being chosen as the sample. The main types of probability sampling methods are simple random sampling, stratified sampling, cluster sampling, multistage sampling, and systematic random sampling the key benefit of probability sampling methods is that they guarantee that the sample chosen is representative of the population. Once you know your population, sampling frame, sampling method, and sample size, you can use all that information to choose your sample importance as you can see, choosing a sample is a .
