Which of the following is true about sampling errors?

• They are caused by the size of the sample.

• They cannot be measured statistically.

• They cannot be measured directly.

• They occur when the findings based on the sample and the true values for a population overlap.

Which of the following is true about nonsampling errors?

• They are not controllable.

• They can be directly measured.

• They can be minimized by increasing the sample size.

• They cannot be statistically measured.

Which of the following is an advantage of person-administered survey methods?

• They eliminate the possibility of an interviewer–respondent interaction error.

• The overall cost of data collection using an interviewer is lower than other data collection methods.

• Interviewers can help ensure respondents are screened to represent the target population.

• In-home and in-office interviews are less time consuming.

Which of the following is a disadvantage of telephone interviews when compared with face-to-face survey methods?

• They make the supervision of interviewers more difficult.

• They tend to be longer than face-to-face survey methods.

• They have high interview refusal rates.

• They can only be conducted in a central location.

Which of the following is an advantage of conducting a mobile phone survey?

• It ensures that there is no time delay between the questions and the receipt of responses.

• It provides relatively large sample sizes.

• It is most suitable for research involving long and/or complex questions and responses.

• It enables consumers to fill out surveys close to the moments of shopping, decision making, and consuming.

Which of the following is an advantage of self-administered surveys?

• They allow researchers to obtain additional in-depth data.

• They eliminate interviewer–respondent bias.

• They eliminate potential response errors.

• They result in high survey response rates.

Data generalizability is the

• extent to which the data are an accurate portrait of a defined target population.

• degree to which a specific question or an investigated issue leads a respondent to give a socially expected response.

• level of preparation required to create an appropriate environment for a respondent.

• degree to which respondents share certain similarities.
