a. simple random sampling
b. quota sampling
c. cluster sampling
d. stratified sampling
e. accidental sampling

7. You want to examine the relationship between family size and family cohesion. You use as your sample all the students in your research methods class. What kind of sampling design are you using?

a. simple random sampling
b. quota sampling
c. cluster sampling
d. stratified sampling
e. reliance on available subjects

8. Every kth element in a list is chosen for inclusion in the sample in

10. If a field researcher wanted to learn a political organization's pattern of recruitment over time, the researcher might begin by interviewing a fairly recent recruit and ask who introduced that person to the organization. Then the researcher might interview the person named and ask who introduced that person to the political organization. This would be an example of

a. snowball sampling
b. systematic sampling
c. deviant cases sampling
d. accidental sampling
e. quota sampling

11. A disadvantage of stratified sampling is that it

a. denies you the use of probability theory
b. requires you to have some prior knowledge about the elements in the population prior to drawing the sample
c. usually increases the standard error
d. usually requires samples that are larger in size than those required by simple random sampling
e. none of the above

12. A study population is

a. the hypothetical aggregation of all the elements in a study
b. the theoretically specified aggregation of study elements
c. that aggregation of elements from which the sample is actually selected

16. Sampling error is typically reduced by either increasing sample size or by increasing the homogeneity of the elements being sampled.

17. The general guideline for the cluster design is to minimize the number of clusters selected while increasing the number of elements within each cluster.

18. Nonprobability sampling is particularly useful in quantitative studies.

19. Findings based on a sample can be taken as representing only the aggregation of elements that compose the sampling frame.
