This Sampling technique uses randomization to make sure that every element of the population gets an equal chance to be part of the selected sample.

This technique divides the elements of the population into small subgroups based on the similarity in such a way that the elements within the group are homogeneous and heterogeneous among the other subgroups formed.

In this sampling, all elements are put together in a sequence first where each element has the equal chance of being selected.

In this sampling, the samples are selected based on the availability. This method is used when the availability of sample is rare and also costly.
