Understanding Cluster Sampling in the Anganwadi Study
The study involves a two-stage sampling process. First, the researcher randomly selects a group of primary units (districts) from the total population of districts. Second, the researcher collects data from all individuals (Anganwadi workers) within the selected primary units.
This method, where the population is divided into clusters (districts in this case), and then a random sample of these clusters is selected, with all individuals within the sampled clusters being studied, is known as Cluster sampling.
Why Other Sampling Methods Don't Fit
- Stratified sampling would involve dividing the districts into subgroups (strata) based on certain characteristics and then randomly sampling from *each* subgroup.
- Quota sampling is a non-probability method where researchers fill quotas for specific subgroups, not based on random selection of groups.
- Convenient sampling relies on easily accessible participants, not a random selection of geographical units like districts.
Therefore, the researcher's approach of randomly selecting five districts and then surveying all Anganwadi workers within those districts is a clear example of Cluster sampling.
