What are the four basic sampling methods?

The samples are taken from the population in four basic methods. They are mentioned below:

a:)Simple Random Sampling

Explanation:

In a simple random sampling technique, each chosen member/element of the sample has the same probability of getting selected as a sample element. This sampling method's main feature is that the selection probability is the same for all the elements in the sampling.

b:)Stratified Random Sampling.

Explanation:

In stratified random sampling, some groups are formed from the population, and then samples are taken from each stratum. The groups have the property of homogeneity within groups, and between groups, there is heterogeneity.

c:)Cluster Sampling.

Explanation:

In cluster sampling, some clusters or groups of elements are created. Then some selected clusters are called samples with heterogeneity within groups, and between-group, there is homogeneity.

d:)Systematic Sampling.

Explanation:)

A sampling interval is specified in systematic sampling, and sample elements are taken according to that specified order.
