Quizplus · Accepted Answer

The sampling technique that is being used in this survey is cluster sampling, as the city blocks from the map represent clusters of the city population. Each block is a group of people that share a common characteristic (living in that block), so choosing a random sample of blocks would help ensure a representative sample of the city population as a whole. The other options, such as convenience and quota sampling, do not involve randomly selecting groups of people or clusters. Stratified sampling involves dividing the population into subgroups based on certain characteristics and then randomly selecting from each subgroup, while systematic sampling involves selecting every nth person from a list or population.
