Question 1

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 factor in deciding between nonprobability and probability sampling methods. The choice is more influenced by the research's objectives, the variability within the population, and considerations related to statistical validity and operational feasibility.

Question 2

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 3

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

Accepted Answer

Sequential sampling has been used to determine preferences between two competing alternatives by allowing a decision to be made once a certain level of evidence in favor of one alternative over the other has been reached. This method is particularly useful in quality control and decision-making processes where choices between two options must be made efficiently.

Question 7

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 involves making a decision rule before sampling begins, which determines when to continue sampling and when enough information has been obtained. This method is useful when the sample size is not known in advance, as it allows for flexibility in the sampling process. Therefore, C is the best choice for this question.

Question 8

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

Accepted Answer

Nonsampling errors are related to issues other than the sampling process itself, such as data collection errors, and do not favor the use of probability sampling.

Question 9

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 as experts identified specific neighborhoods, indicating a non-random, expert-driven selection process. In Saudi Arabia, convenience sampling was employed through the snowball procedure, which relies on existing study participants to recruit future participants, a method often used when there are challenges in accessing the target population directly.

Question 10

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 to execute them properly. Therefore, lack of trained researchers is not a reason for the uncommon use of probability sampling techniques in international marketing research. On the other hand, international marketing research often faces difficulties in finding suitable sampling frames, inaccessibility of certain target respondents, and dominance of personal interviewing, which make probability sampling techniques more challenging to implement.

Question 11

How can mobile samples be made more representative?

Accepted Answer

The answer of How can mobile samples be made more...

Question 12

Cluster sampling and stratified sampling differ in all of the following ways except ________.

Accepted Answer

Cluster sampling and stratified sampling are both classification of sampling techniques and differ in their approach to subpopulations, homogeneity and heterogeneity, and objectives.

Question 13

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

Accepted Answer

Snowball sampling involves asking participants to refer others who possess the rare characteristic being studied. This technique can help the researcher locate and include more individuals with the rare characteristic, resulting in a better estimation of its frequency in the population.

Question 14

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

Accepted Answer

Sampling details that are too revealing and verbatim quotations in reports to the client can both potentially compromise the anonymity of respondents. Therefore, the researcher must be careful in how they disclose these details or quotes. The large population size does not necessarily pose ethical concerns related to anonymity preservation.

Question 15

Question 18

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 used in Internet research. Option A involves renting e-mail lists from suppliers to recruit participants for the study. Option B involves conducting short telephone screening interviews to recruit participants for the study. Finally, option C involves distributing fliers to customers of a store, directing them to a specific, password-protected site to participate in the study.

Question 19

________ 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 using a preliminary sample to identify the elements to be included in the final sample. This can be useful when a sampling frame is not readily available, but when information is available about a broader frame within which the elements are believed to be contained. The preliminary sample is used to identify a smaller set of elements that can be feasibly sampled or enumerated, which are then used to inform the selection of the final sample. Double sampling can improve the accuracy of the final sample by reducing the potential for bias that may arise from using an incomplete or inaccurate 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) ________.

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) ?
