Match the List-I with List-II:​

Choose the correct answer from the options given below:

Correct option is A

The correct matching of List-I (Nature of Study) with List-II (Choice of Sampling Method) is:

• A-IV (Size of all strata is equal → Stratified random sampling):
  In stratified random sampling, the population is divided into strata (groups) of equal size, and random sampling is performed within each stratum. This ensures fair representation from all strata.

• B-III (Information can be provided by few respondents → Judgement sampling):
  Judgement sampling involves selecting respondents who are most likely to provide the required information, based on the researcher’s judgment. It is often used when only a few respondents have the necessary expertise.

• C-I (Information is required from particular strata of population → Quota sampling):
  In quota sampling, specific strata or groups are identified, and a fixed quota of respondents is chosen from each group to ensure representation of that stratum.

• D-II (To obtain quick information → Convenience sampling):
  Convenience sampling involves selecting respondents based on their availability and accessibility, making it a fast and cost-effective method for obtaining quick information.

Information Booster

1. Stratified Random Sampling: Ensures fair representation across all strata. It is used when strata sizes are equal or need to be proportionally represented.
2. Judgement Sampling: Relies on expert knowledge to select participants, often used in specialized studies.
3. Quota Sampling: Targets specific groups with fixed quotas, ensuring diversity and representation of key segments.
4. Convenience Sampling: Prioritizes speed and accessibility, often used in exploratory research or when resources are limited.
