The given statement is false.

Systematic, stratified, and cluster sampling techniques are quite different, and in no way do they approximate simple random sampling.

Systematic random sampling makes use of a computer algorithm by defining the root of the algorithm as any one from the observations.

Stratified sampling makes use of the formation of blocks that are as homogeneous as possible within the block and heterogeneous with respect to the other blocks.

Cluster sampling is the sampling technique wherein clusters are formed on the basis of section units that are homogeneous when considered as a whole but are quite heterogeneous within.
