Answer

Brief Explanations:

  1. In cluster sampling, the population is divided into groups (clusters). Here, the blocks are clusters. First, 10 blocks are chosen, and then all residents within the selected houses in those blocks are interviewed.
  2. In simple - random sampling, each individual in the population has an equal chance of being selected directly without first dividing into groups.
  3. Stratified sampling divides the population into strata based on some characteristic and samples from each stratum.
  4. Systematic random sampling selects elements at regular intervals from an ordered list.

Answer:

cluster sampling.
