Exam 11: Sampling: Design and

Quota sampling ensures that the composition of the sample is the same as the composition of the population with respect to the characteristics of interest.

The researcher has the ethical obligation to protect the identities of the respondents, even if it means limiting the level of sampling detail that is reported to the client and other parties.

Nonprobability samples do not allow for objective evaluation of the precision of the sample results.

requires a detailed specification of how the sampling design decisions with respect to the population, sampling frame, sampling unit, sampling techniques, and sample size are to be implemented.

attempts to obtain a sample of convenient elements. The selection of sampling units is left primarily to the interviewer.

is a sampling technique in which an element cannot be included in the sample more than once.

A major issue related to Internet sampling is representativeness because of lack of computer ownership and Internet access in many households.

Systematic sampling is different from simple random sampling in that only the permissible samples of size n that can be drawn have a known and equal probability of selection. The remaining samples of size n have zero probability of being selected.

A census can greatly decrease nonsampling error.

For simple random sampling, the researcher assumes that the population elements are ordered in some respect.

Discuss some of the problems in implementing the sampling design process when conducting international marketing research.

The target population should be defined in terms of all of the following except .

is a probability sampling technique in which each element in the population has a known and equal probability of selection. Every element is selected independently of every other element and the sample is drawn by a random procedure from a sampling frame.

Which sampling technique can help the researcher estimate rare characteristics (Table 11.4 in the text)?

All of the factors listed below favor the use of probability sampling except (Table 11.5 in the text).

Sample size is influenced by the average size of samples in similar studies.

is a sampling procedure in which each element of the population has a fixed probabilistic chance of being selected for the sample.

Sampling techniques and procedures vary in accuracy, reliability, and cost from country to country.

_ can be useful when no sampling frame is readily available for selecting final sampling units but when the elements of the frame are known to be contained within a broader sampling frame.

The choice between nonprobability and probability samples should be based on all of the following considerations except (Table 11.5 in the text).
