Question 1

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

Accepted Answer

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

Question 2

Which statement is not true about not-at-homes?
A) Consumers are more likely to be at home on weekdays than on weekends.
B) Consumers are more likely to be at home in the evening as opposed to during the afternoon.
C) People with small children are more likely to be at home than single or divorced people.
D) Pre-notification and appointments increase the likelihood that the respondent will be at home when contact is attempted.

Accepted Answer

The statement that consumers are more likely to be at home on weekdays than on weekends is not true. In fact, the opposite is often true, as many people work or have other obligations during the week and are more likely to be at home on weekends.

Question 3

________ 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.
A) Trend analysis
B) Weighting
C) Subjective estimates
D) Imputation

Accepted Answer

Imputation is a method of adjusting for nonresponse by filling in missing values with estimates based on available data. It is often used when there is a large amount of missing data and can be done using various statistical techniques, including predictive modeling and hot-deck imputation.

Question 4

Which method of adjusting for nonresponse involves evaluating the likely effects of nonresponse based on experience and available information?
A) replacement
B) subjective estimates
C) sub-sampling of nonrespondents
D) substitution

Accepted Answer

Subjective estimates involve using expert judgment and available information to make educated guesses about the likely effects of nonresponse on the study results. This method is commonly used when there is no information available about the nonrespondents, such as in a survey of the general population where contact information is limited. While sub-sampling of nonrespondents and substitution are other methods for adjusting for nonresponse, they are not based on subjective estimates and may not be appropriate in all situations. Replacement involves imputing missing data with values from other sources, which may not be accurate if the missing values are significantly different from the available data.

Question 5

________ 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.
A) Imputation
B) Subjective estimates
C) Subsampling of nonrespondents
D) None of the above are correct.

Accepted Answer

The method described is not accurately represented by any of the given options. The method is often referred to as "trend analysis" or "extrapolation" based on response timing, which is not listed among the choices.

Question 8

________ is a statistical procedure that attempts to account for nonresponse by assigning differential weights to the data depending on the response rates.
A) Trend analysis
B) Imputation
C) Weighting
D) Subjective estimates

Accepted Answer

Weighting is a statistical procedure often used to account for nonresponse bias in survey research. This involves assigning differential weights to the data depending on the response rates. This allows for the data to be more representative of the population being studied. Trend analysis refers to the study of how a variable changes over time, while imputation involves estimating missing data based on other available data. Subjective estimates involve using personal judgments or opinions to make predictions or estimates.

Question 9

Ethical dilemmas associated with sample size determination include all of the following except ________.
A) what should be done when a difference in the actual standard deviation and the estimated standard deviation results in a larger confidence interval than desired
B) inflating the standard deviation to increase sample size and project revenue
C) investigating the possibility of non-response bias and making a reasonable effort to adjust for it
D) All of the above pose ethical dilemmas.

Accepted Answer

The answer of Ethical dilemmas associated with sample size determination...

Question 10

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?
A) substitution
B) replacement
C) sub-sampling of nonrespondents
D) subjective estimates

Accepted Answer

Sub-sampling of nonrespondents involves contacting a sub-sample of the nonrespondents, projecting the values obtained from the sub-sample to all respondents, and then adjusting the survey results to account for nonresponse. This method is considered one of the best and most effective ways to adjust for nonresponse bias.

Question 11

Which method of improving response rate involves sending potential respondents a postcard or letter to remind nonrespondents to complete and return the questionnaire?
A) motivating the respondents
B) incentives
C) prior notification
D) follow-up

Accepted Answer

Follow-up involves sending reminders or follow-up emails, postcards, or letters to non-respondents to encourage them to complete and return the questionnaire. This method has been proven to significantly increase response rates.
