Cluster sampling is desirable when similar clusters can be easily identified. This allows for a more efficient and effective sampling process, as it reduces the amount of variation within clusters and increases the representativeness of the sample. Dissimilar clusters may lead to greater variability and may not be as representative of the population of interest. A non-group is not a relevant criterion for cluster sampling, and non-contiguous clusters can be addressed through stratified sampling or other techniques.
