Discussion

Researcher studied the impact of literacy on women's decision-making in Gramsabhas in Maharashtra. In order to select women respondents from the Gramsabhas sampling was done at three levels, namely, district, talukas and villages.

Which of the following techniques of sampling was used by the researcher ?

  • A.Stratified sampling
  • B.Multistage sampling
  • C.Quota sampling
  • D.Sequential sampling

Answer: B

The researcher used Multistage sampling.

In multistage sampling the sample is drawn in successive stages, each from within the units chosen at the stage before. Here districts were chosen first, then talukas within those districts, then villages within those talukas, and finally women respondents from the Gramsabhas of those villages. That chain of levels is the defining feature.

Stratified sampling divides the population into strata, such as caste or income groups, and samples from every stratum, rather than narrowing down through levels. Quota sampling fills fixed numbers non-randomly. Sequential sampling keeps adding cases until a decision can be reached, with no fixed sample size.
