The most appropriate sampling Technique to represent the heterogenous population of a region is :

  • A.Cluster
  • B.Random stratified
  • C.Systematic
  • D.Purposive

Answer: B

The most appropriate sampling technique for representing the heterogeneous population of a region is stratified random sampling, where the population is divided into homogeneous strata and a random sample is taken from each.

Cluster sampling suits groups that are similar to each other, systematic sampling spreads units at a fixed interval and purposive sampling relies on judgement, so they do not secure the representation of every different group.
