Sampling methods There are 4 basic sampling methods we have learned do far: simple random sampling‚ stratified sampling‚ clusters and systematic sampling. When we do experiments we need to use the right sampling method in order to make the experiment useful and successful. First‚ simple random sampling; it gives a sample selected in a way that gives every different sample of size n an equal chance of being selected. Second‚ stratified sampling; it divides a population into subgroups and then takes
