We know that,
* Convenience sampling is a type of non-probability sampling that involves the sample being drawn from that part of the population that is close to hand
* In stratified sampling, researchers divide subjects into subgroups called strata based on characteristics that they share Once divided, each subgroup is randomly sampled using another probability sampling method.
* random sample is a subset of individuals chosen from a larger set in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way
* Cluster sampling is a probability sampling technique where researchers divide the population into multiple groups (clusters) for research. So researchers then select random groups with a simple random or systematic random sampling technique for data collection and analysis.
* systematic sampling is a statistical method involving the selection of elements from an ordered sampling frame. The most common form of systematic sampling is an equiprobability method.
