80. If we were to ask college students, "To what extent do they value a college degree?", which type of sample plan
would be most appropriate?
a.
Any probability sampling plan would be useful.
b.
A stratified sample because we would expect the answers to vary by strata: freshmen, sophomore, junior,
and senior.
c.
A cluster sample because we would expect the answers to vary by cluster: freshmen, sophomore, junior, and
senior.
d.
An area sample because we would expect the answers to vary by area: freshmen, sophomore, junior, and
senior.
e.
None of these would be appropriate. In fact, it would be best to use a nonprobability sampling technique.

101. Compare and contrast probability and nonprobability sampling.
ANSWER:
In a probability sample, each member of the target population has a known, nonzero
chance of being included in the sample. The chances of each member of the target
population being included in the sample may not be equal, but everyone has a known
probability of inclusion. With nonprobability samples, on the other hand, there is no way
of estimating the probability that any population element will be included in the sample.
Thus, there is no way of ensuring that the sample is representative of the target
population. All nonprobability samples rely on personal judgment at some point in the
sample-selection process.
