Simple sampling - A method where individuals are chosen randomly from a larger set.

Convenience sampling - The sample is being chosen as per ease of access thus it is not a random sampling.

Systematic sampling - Probability method where elements are chosen from a target population.

Stratified sampling - Method where population were divided into different groups called strata and the sample is then drawn from each group.

Cluster sampling - Population is where population were divided into different groups known as clusters. The clusters were then chosen randomly as the samples.
