Explain two methods of choosing sampling.

Explanation

  • Stratified sampling: It divides the population by certain characteristics into different homogeneous strata (like, PhD students, masters, bachelors) . Elements in each stratum is homogeneous but are heterogeneous across. After selecting the strata, a simple random sampling or systematic random sampling is done on each stratum to the proportion of each strata.
  • Quota Sampling: In quota sampling the population is first segmented into mutually exclusive sub-groups, as in stratified sampling. Then the judgement of the investigator is used in selecting the subjects or units from each segment in a proportion. E. g. Interview took sample of 200 females and 400 males between the age group 35 - 55.
