Question 1

Blame for response errors usually falls on the

Accepted Answer

Response errors can be caused by both the researcher (for example, by wording questions poorly or selecting a biased sample) and the respondent (for example, by misinterpreting questions or providing inaccurate information). Therefore, blame for these errors can fall on both parties.

Question 2

The refusal problem is the main source of nonresponse bias for a(n)

Accepted Answer

The refusal problem (when individuals refuse to participate or respond to a survey) is most common in mail surveys, making option C the best choice. This is because mail surveys typically have lower response rates compared to other survey methods, such as phone or in-person interviews or panel surveys. The nonresponse bias resulting from refusals can affect the validity of the results in a mail survey, as nonrespondents may differ from respondents in important ways.

Question 3

Effective strategy(ies)to increase initial response rates is(are)

Accepted Answer

Offering a simple task initially and providing monetary incentives are effective strategies to increase initial response rates. Quota sampling is more about ensuring sample representation rather than increasing response rates.

...

Question 5

During a recent telephone survey,the data collection effort produced the following results: completed interviews = 400;refusals = 200;not-at-home = 400 What is the response rate in this particular situation?

Accepted Answer

The answer of During a recent telephone survey,the data collection...

Question 6

The not-at-home problem is handled LEAST effectively by

Accepted Answer

Substituting a neighboring dwelling may not always be practical or ethical as it involves entering someone else's property without their consent. It also does not guarantee that the person being substituted will have similar characteristics as the original sample member. Therefore, it is the least effective method of handling the not-at-home problem.

Question 7

The number provided by the calculation,"number of sample units contacted divided by the total number of sample units approached" is commonly called the

Accepted Answer

The answer of The number provided by the calculation,"number of...

Question 8

Not-at-home nonresponse bias is most affected by

Accepted Answer

Not-at-home nonresponse bias occurs when selected individuals are not available or refuse to participate, often due to scheduling conflicts or lack of interest. This type of bias can be minimized through effective interviewer training, which includes techniques for engaging participants and overcoming objections. Therefore, choice A, interviewer training, is the best option for minimizing not-at-home nonresponse bias. The other choices, such as sample size, subject of research, and sample design, may also have an impact on nonresponse bias, but are not as directly related to addressing not-at-home nonresponse bias as interviewer training.

Question 9

An interviewer is assigned to visit 123 eligible households.After the first approach to each household,52 contacts have been made.At this stage,what is the interviewer's contact rate?

Accepted Answer

The contact rate is calculated by dividing the number of contacts made (52) by the total number of eligible households (123) and then multiplying by 100 to get a percentage: (52/123) * 100 = 42.3%.

Question 10

...

Question 11

Which of the following statements concerning response errors is FALSE?

Accepted Answer

Pre-testing the questionnaire with members of the relevant population is generally effective at identifying problems due to respondents misunderstanding questionnaire items, not eliminating them entirely. Therefore, statement D is false.

Question 12

The contact rate can be used to

The answer of The contact rate can be used to

Question 14

An interviewer finds that a subject is not at home;to complete his sample,he substitutes the nearest available subject for the missing subject.This practice is

Accepted Answer

Substituting the nearest available subject for the missing subject is not recommended as it can complicate the problems by increasing the proportion of at-homes in the sample. This can bias the results and make them less accurate. It is better to try to reach the missing subject at a later time or to replace them with a randomly selected subject from the same population.

Question 15

Refusals are a more important source of nonresponse bias than the not-at-home problem in

Accepted Answer

The answer of Refusals are a more important source of...

Question 16

Which of the following has NOT been shown to be effective in decreasing the number of refusals?

Accepted Answer

All of the given options have been shown to be effective in decreasing the number of refusals. Therefore, none of them can be considered as the option that has NOT been shown to be effective.

Question 17

The rate of refusals depends on the

Accepted Answer

The answer of The rate of refusals depends on the
...

Question 18

The respondent's cooperation will NOT be encouraged by

Accepted Answer

Asking sensitive questions can potentially make the respondent uncomfortable and less likely to cooperate. Therefore, it does not encourage their cooperation. The other options are factors that can contribute to encouraging cooperation.

Question 19

Sherry Smith is an interviewer for a marketing research company.During a recent telephone study she successfully contacted 400 of the 600 households that she had attempted to contact.Of those successfully contacted,300 households completed the survey.What is Sherry's contact rate?

Accepted Answer

The contact rate is the percentage of households that Sherry successfully contacted out of the total attempted, which is calculated as follows:

Contact Rate = (Number of Successful Contacts / Number of Attempted Contacts) x 100%

Plugging in the given values, we get:

Contact Rate = (400 / 600) x 100% = 67%

Therefore, the correct answer is B)67%.

Question 20

The empirical evidence suggests which of the following does NOT affect the refusal rate?

Accepted Answer

All the listed factors can influence the refusal rate in research studies.
