Questions: For each stage in the multistage sampling plan of this study, identify the sampling technique that was used: From each region, 5 representative counties are selected. (In total, all the claims originating from 35 counties are examined.) cluster sampling simple random sample stratified sampling

Solution Steps

In the first stage, 5 representative counties are selected from each region. This can be considered as stratified sampling if regions are treated as strata. In stratified sampling, the population is divided into distinct subgroups (strata) and random samples are taken from each subgroup.

In the second stage, all claims originating from the selected counties are examined. This aligns with cluster sampling, where entire clusters (in this case, counties) are selected, and all elements within those clusters are included in the sample.
