Question

question 7 (2 points) if you were told that a class of twenty was questioned for a poll about study habits on campus, this would be an example of ___. stratified sampling cluster sampling random sampling systematic sampling

Explanation:

Stratified sampling divides the population into subgroups (strata). Cluster sampling divides the population into clusters and samples entire clusters. Random sampling selects individuals randomly from the whole population. Systematic sampling selects individuals at regular intervals. Here, a whole class (a cluster) is sampled, so it's cluster sampling.

Answer:

cluster sampling
