In the context of errors in surveys, identify a true statement about sampling error.

It refers to the difference between the true values for a population and the findings based on the sample.

Which of the following are true of Internet surveys? (Check all that apply.)

Missing data can be reduced substantially as respondents are prompted to answer a question before they can move to the next screen. The effects of question order on responses can be removed by randomizing the order of questions within a group.

Quality requirements Completion Budget

Identify the true statements about data quality requirements that a researcher should consider when selecting a survey method. (Check all that apply.)

Researchers who have complete data can paint a total picture by fully describing the information from each respondent. The generalizability of data collected using any technique will be limited if the sample size is small.

Respondent participation Incidence rate Diversity

Which of the following is a disadvantage of mail surveys as a method of data collection?

Respondents who misunderstand questions tend to record responses that were not expected by the researchers.

______ ______ or faulty error occurs when respondents have impaired memory or do not respond accurately.

Response Error

Identify the task characteristics that researchers should consider when selecting a survey method. (Check all that apply.)

The amount of information required from participants The difficulty of the task given to participants Stimuli required to elicit a response from participants

Identify the disadvantages of using telephone interviews to collect data. (Check all that apply.)

The complexity of some questions increases when they have to be answered over the telephone. This method does not typically allow nonaudio stimuli to be presented to respondents over the telephone.

Identify the advantages of using online surveys to collect data. (Check all that apply.)

The costs of copying surveys, buying postage, or hiring interviewers are eliminated. The expense per respondent is low when compared to other survey methods.

Which of the following are differences between causal research designs and exploratory or descriptive research designs? (Check all that apply.)

The hypotheses of exploratory designs focus on the magnitude and/or direction of an association, while the hypotheses of causal designs focus on causality. Exploratory and descriptive designs usually lack the control mechanism of causal designs.

Which of the following is a drawback of using telephone interviews to collect data?

The public has a poor perception of telephone interviews because of sugging.

Which of the following are true of the task characteristics that researchers should consider when selecting a survey method? (Check all that apply.)

The researchers should attempt to make it as easy as possible for respondents to answer questions. Respondents need to be exposed to some kind of stimulus to elicit a response. Respondent fatigue increases and response rates lower when large amounts of data are collected

In the context of errors in surveys, identify the factors that cause sampling errors. (Check all that apply.)

The sample size used The method of sampling used

Which of the following is a true statement about laboratory (lab) experiments?

The settings can be controlled by a researcher, which leads to the establishment of high internal validity.

Which of the following is a disadvantage of mobile phone surveys?

They are unsuitable for research that involves complex and/or long questions and responses.

Which of the following are advantages of mail surveys? (Check all that apply.)

They can reach hard-to-interview people. The costs associated with these surveys are limited to postage, printing, and the cost of incentives.

Identify the characteristics of nonsampling errors that occur in survey research. (Check all that apply.)

They result from some human error in either the design or the execution of a survey. They have a tendency to create "systematic variation" or bias in the data.

Identify the broad applications of test marketing in marketing research. (Check all that apply.)

To explore different marketing mix elements To examine product weaknesses, strengths, or inconsistencies in marketing strategies To pilot test new product introductions or product modifications

Which of the following are true of nonsampling errors that occur in survey research? (Check all that apply.)

Unlike random sampling error, they cannot be directly measured. They can lead to other nonsampling errors.

One major drawback of mail surveys is that _____.

An advantage of telephone interviews is that they _____.

are more affordable, quicker, and better suited for collecting data from a large sample than face-to-face interviews

Marketing researchers usually avoid making calls to mobile phone users to solicit participation as often as they do over landlines because _____.
