Simple random sampling ensures that every member of the group has an equal chance of being included in the sample, thus providing a representative sample of the population. Cluster sampling involves dividing the population into clusters, and only sampling from selected clusters, thus potentially introducing bias. Systematic sampling involves selecting every nth individual, which can also introduce bias if the sampling interval happens to coincide with any patterns in the population. Convenience sampling involves choosing individuals who are readily available, which does not provide a representative sample of the population. Purposeful sampling involves selecting individuals who meet certain criteria, which can be useful in certain research scenarios but may not provide a representative sample of the population.
