Cluster sampling is being used because the blocks are being grouped together as a cluster and then randomly selected for the sample. This is different from stratified sampling where the blocks would be divided into strata based on a particular characteristic and then randomly selected from each stratum. It is also different from systematic sampling where a sampling interval is set and every nth block is selected, and multistage sampling where multiple sampling techniques are used.
