b. Judgment sampling
c. Simple random sampling
d. Quota sampling
16. The __________ refers to the entire group of people, events, or things of interest that the researcher wishes to investigate.

d. Sampling unit.
17. _____________ is a single member of the population.
a. A sampling unit.
b. An element.
c. A subject.
d. A participant.
18. Non-probability sampling designs are used when the representativeness of the sample is of importance in the interests of wider generalizability.
a. T
b. F
19. The characteristics of the ___________ such as m (the mean), s (the standard deviation), and s2 (the variance) are referred to as its parameters.
a. Respondents
b. Sample
c. Population

a. T
b. F
27. From a practical, probability sampling is preferred over non-probability sampling.
a. T
b. F
28. Cluster sampling can be considered a form of proportionate stratified sampling, in which a predetermined proportion of people are sampled from different groups, but on a convenience basis.
