Exam 11: Sampling: Design and Procedures

________ has been used to determine preferences for two competing alternatives.

In ________, the target population is first divided into mutually exclusive and collectively exhaustive subpopulations, or clusters.

________ is a form of convenience sampling in which the population elements are selected based on the judgment of the researcher.

The logic behind proportionate sampling is simple. Strata with larger relative sizes are more influential in determining the population mean, and these strata should also exert a greater influence in deriving the sample estimates.

The inferences that link sample characteristics and population parameters are estimation procedures and tests of hypotheses.

A complete enumeration of the elements of a population or study objects is a ________.

The aggregate of all the elements, sharing some common set of characteristics, that comprises the universe for the purpose of the marketing problem is the ________.

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

To avoid sampling errors, the Internet researcher must be able to control the pool from which respondents are selected.

The sample size decision should be guided by certain qualitative considerations. Which of the following is not one of those considerations?

A subgroup of the elements of the population selected for participation in the study is a ________.

The criteria for the selection of stratification variables consist of all of the following except ________.

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

The elements within a stratum should be as heterogeneous as possible, but the elements in different strata should be as homogeneous as possible.

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

A representation of the elements of the target population consisting of a list or set of directions for identifying the target population is a ________.

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.

________ is a probability sampling technique in which the sample is chosen by selecting a random starting point and then picking every ith element in succession from the sampling frame.

In simple random sampling, each element in the population has a known and equal probability of selection.

Consumer research conducted in Mexico and Saudi Arabia used different sampling techniques for the same study. In Mexico, ________ was used by having experts identify neighborhoods where the target respondents lived; homes were then randomly selected for interviews. In Saudi Arabia, ________ employing the snowball procedure was used because there were no lists from which sampling frames could be drawn and social customs prohibited spontaneous personal interviews.
