The distinguishing feature of cluster samples in comparison to other probability
sampling plans is that cluster samples
a. provide each population element with an equal chance of being included in the
sample.
b. provide each population element with a known chance of being included in the
sample.
c. involve the partitioning of the parent population into mutually exclusive and
exhaustive subsets.
d. involve the partitioning of the parent population into mutually exclusive and
exhaustive subsets and the probabilistic selection of elements from each subset.
e. utilize the probabilistic selection of groups rather than elements.
