Question 1

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

Accepted Answer

Sequential sampling is used to determine preferences for two competing alternatives by evaluating samples in stages and making decisions at each stage.

Question 2

Discuss the advantages of systematic sampling.

Accepted Answer

The answer of Discuss the advantages of systematic sampling....

Question 3

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.

Accepted Answer

In Mexico, judgmental sampling was used by having experts identify neighborhoods, while in Saudi Arabia, convenience sampling employing the snowball procedure was used due to the lack of sampling frames and social customs.

Question 4

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

Accepted Answer

Probability sampling is not favored when nonsampling errors are likely to be an important factor, as these errors can affect the accuracy of the results regardless of the sampling method used.

Question 5

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

Accepted Answer

The answer of Discuss some of the problems in implementing...

Question 6

In ________ the sample size is not known in advance,but a decision rule is stated before the sampling begins.At each stage,this rule indicates whether sampling should be continued or whether enough information has been obtained.

Accepted Answer

Sequential sampling is a type of sampling where the sample size is not known in advance, but a decision rule is stated before the sampling begins. This rule indicates whether sampling should be continued or whether enough information has been obtained. This type of sampling is useful when the cost of obtaining additional samples is high or when the sample size cannot be determined before the study is conducted. Therefore, the best choice for this question is A) sequential sampling.

Question 7

________ 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.

Accepted Answer

Double sampling involves selecting a smaller sample from within a larger sample, where the larger sample contains all possible elements. It can be useful when a comprehensive sampling frame is not available but some information about the elements is known. The first phase involves selecting a smaller sample from the known information, and the second phase involves using the information from the first phase to select a final sample. This can improve the accuracy of the sample selection process. Stratified sampling involves dividing the population into subgroups based on specific characteristics and then sampling from each subgroup. Systematic sampling involves selecting every nth element from a list or sequence. Sequential sampling involves conducting additional sampling based on the results of previous samples, which may not be relevant in this case.

Question 8

When is it meaningful to sample potential respondents who are surfing the Internet?

Accepted Answer

The answer of When is it meaningful to sample potential...

Question 9

Which situation poses ethical concerns for the researcher in terms of preserving the anonymity of the respondents?

Accepted Answer

Verbatim quotations and sampling details can disclose the identity of the respondents, which compromises their anonymity. Therefore, both options B and C pose ethical concerns for the researcher regarding anonymity preservation.

Question 10

All of the following are examples of nonpanel recruited sampling methods used in Internet research except ________.

Accepted Answer

All of the options listed are examples of nonpanel recruited sampling methods, so none of them are exceptions.

Question 11

Discuss the advantages of convenience samples and when it is appropriate to use them.

Accepted Answer

The answer of Discuss the advantages of convenience samples and...

Question 12

Which sampling technique can increase representativeness,is easier to implement than simple random sampling and does not require a sampling frame (Table 11.4 in the text)?

Accepted Answer

The answer of Which sampling technique can increase representativeness,is easier...

Question 13

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

Accepted Answer

Snowball sampling can help the researcher estimate rare characteristics by targeting a small population that may have the rare characteristics and then using those individuals to refer others who may share the rare characteristic. This method is useful for identifying hard to reach populations with rare characteristics.

Question 14

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

Accepted Answer

The size of the population is not a primary consideration when choosing between nonprobability and probability samples. The focus is more on variability, statistical considerations, and the nature of the research.

Question 15

Discuss the uses of nonprobability and probability sampling.

Accepted Answer

The answer of Discuss the uses of nonprobability and probability...

Question 16

Probability sampling techniques are uncommon in international marketing research because of all of the following reasons except ________.

Accepted Answer

Probability sampling techniques require trained researchers, and the lack of trained researchers is a barrier to using these techniques in international marketing research. However, lack of suitable sampling frames, inaccessibility of certain respondents, and dominance of personal interviewing are all other barriers that make probability sampling techniques uncommon in international marketing research.
