Question 1

________ is a method of adjusting for nonresponse in which the researcher tries to discern a trend between early and late respondents.This trend is projected to nonrespondents to estimate their characteristic of interest.

Accepted Answer

The method described is not accurately captured by any of the given options. The method of adjusting for nonresponse by analyzing trends between early and late respondents is typically referred to as "extrapolation" or "trend analysis," which is not listed among the choices.

Question 2

________ is a method to adjust for nonresponse by assigning the characteristic of interest to the nonrespondents based on the similarity of the variables available for both nonrespondents and respondents.

Accepted Answer

Imputation is a method to estimate missing values by assigning values based on the similarity of respondents and nonrespondents. This helps to adjust for nonresponse bias and ensure that the sample is more representative of the population of interest. Alternatively, weighting adjusts the sample to match the population, trend analysis examines changes over time, and subjective estimates rely on expert opinion without statistical methods.

Question 3

Which method of adjusting for nonresponse has the researcher contacting a sub-sample of the nonrespondents;projecting the values obtained from the sub-sample to all respondents;then adjusting the survey results to account for nonresponse?

Accepted Answer

Sub-sampling of nonrespondents involves contacting a sub-sample of the nonrespondents and projecting the values obtained from the sub-sample to all respondents. This method allows for a more accurate adjustment for nonresponse as it takes into account the specific characteristics of the nonrespondents. The other options listed are not as effective in adjusting for nonresponse.

Question 4

Discuss four of the methods of reducing refusals to participate in a survey.

Accepted Answer

The answer of Discuss four of the methods of reducing...

Question 5

Which method of improving response rate involves sending potential respondents a postcard or letter to remind nonrespondents to complete and return the questionnaire?

Accepted Answer

Sending a follow-up postcard or letter is a method of improving response rate by reminding nonrespondents to complete and return the questionnaire. Motivating the respondents refers to giving them a reason to want to participate, incentives involve offering a reward for participation, and prior notification involves informing potential respondents beforehand about the upcoming survey. While these methods can also be effective, sending a follow-up reminder postcard or letter is the best choice for specifically targeting nonrespondents and encouraging them to participate.

Question 6

Discuss sample size determination in the context of mobile marketing research.

Accepted Answer

The answer of Discuss sample size determination in the context...

Question 7

Which method of adjusting for nonresponse involves evaluating the likely effects of nonresponse based on experience and available information?

Accepted Answer

Subjective estimates involve making educated guesses based on past experience and available data to account for nonresponse. It is a practical method to adjust for missing data when other more complex methods are not feasible.

Question 8

________ is a statistical procedure that attempts to account for nonresponse by assigning differential weights to the data depending on the response rates.

Accepted Answer

Weighting is a statistical procedure that accounts for nonresponse by adjusting the weights assigned to respondents in order to reflect the overall population. This technique is useful in correcting sampling bias caused by nonresponse, which can result in biased estimates of population parameters. Trends analysis involves using statistical techniques to identify patterns and trends in data over time. Subjective estimates are based on personal judgment or opinion and may be subject to bias. Imputation is a statistical technique for filling in missing data with estimated values. While imputation can be a useful tool, it may introduce bias if the imputed values are not representative of the true data.

Question 9

Ethical dilemmas associated with sample size determination include all of the following except ________.

Accepted Answer

All of the above pose ethical dilemmas.

Question 10

Which statement is not true about not-at-homes?

Accepted Answer

The statement that consumers are more likely to be at home on weekdays than on weekends is not true. In fact, many people work during the weekdays and may not be at home during the day, while they may have more free time on the weekends and be more likely to be at home.

Question 11

Discuss why there may be ethical concerns when using the standard deviation of a variable in determining sample size.

Accepted Answer

The answer of Discuss why there may be ethical concerns...

Question 12

Discuss what can be done to reduce not-at-homes.

Accepted Answer

The answer of Discuss what can be done to reduce...

Question 13

Which method of improving response rate involves use of the foot-in-the-door or door-in-the-face technique?

Accepted Answer

The foot-in-the-door technique involves getting a person to agree to a large request by first setting them up by having that person agree to a modest request. The door-in-the-face technique, on the other hand, involves making a large request that is expected to be refused so that the person will be more likely to agree to a smaller request later. Both techniques are psychological strategies used to motivate respondents to participate, making choice A correct.

Question 14

Which method of improving response rate involves sending potential respondents a letter notifying them of the imminent mail,telephone,personal,or Internet survey?

Accepted Answer

Prior notification involves sending potential respondents a letter notifying them of the imminent survey, which can increase response rates by giving the respondents a heads up and preparing them mentally for the survey. Motivating the respondents, follow-up, and incentives are also methods to improve response rates, but they are not specifically related to sending a prior notification.

Question 15

Which method of improving response rate involves offering potential respondents monetary and non-monetary gifts?

Accepted Answer

Offering incentives, both monetary and non-monetary, can motivate potential respondents to participate in a survey and increase the response rate. It is a common and effective method used to improve response rates.
