After studying this chapter, you should be able to
Interviews as Interactive Communication
• Interactive Survey Approaches– Those that allow spontaneous two-way interaction
between the interviewer and the respondent.– Can be either personal or electronic.
• Noninteractive Media– Those that do not facilitate two-way
communication and are largely a vehicle by which respondents give answers to static questions.
• Tradition forms with less flexibility• Self-administered mail and Internet surveys
10–3
Personal Interviews
• A personal interview is a form of direct communication in which an interviewer asks respondents questions face-to-face.– Versatile and flexible– Truly interactive

Door-to-Door Interviews
• Personal interviews conducted at respondents’ doorsteps in an effort to increase the participation rate in the survey.
• Callbacks– Attempts to recontact individuals selected for a
sample who were not available initially.
10–7
Door-to-Door Interview Characteristics
• Speed of data collection: moderate to fast
• Geographical flexibility: limited to moderate
• Respondent cooperation: excellent
• Versatility of questioning: quite versatile
• Questionnaire length: long• Item nonresponse: low• Possibility of respondent
misunderstanding: lowest
• Degree of interviewer influence of answer: high
• Supervision of interviewers: moderate
• Anonymity of respondent: low• Ease of call back or follow-up:
difficult• Cost: highest due to travel costs• Special features: visual materials
may be shown or demonstrated; extended probing possible
10–8
Mall Intercept Personal Interview
• Personal interviews conducted in a shopping mall.
• Interviewers typically intercept shoppers at a central point within the shopping center or at the main entrance.
10–9
Mall Intercept Interview Characteristics
• Speed of data collection: fast• Geographical flexibility: confined,
urban bias• Respondent cooperation:
moderate to low• Versatility of questioning:
extremely versatile• Questionnaire length: moderate
to long• Item nonresponse: medium• Possibility of respondent
misunderstanding: lowest
• Degree of interviewer influence of answers: highest
• Supervision of interviewers: moderate to high
• Anonymity of respondent: low
• Ease of call back or follow-up: difficult
• Cost: Lower than door-to-door
• Special features: taste tests, viewing of TV commercials possible
10–10
Personal Interviews
• Global Considerations– Variations in willingness to participate
• Sensitivity to interview subject matter
• Beliefs about appropriate business conduct
10–11
Telephone Interviews
• Telephone Interviews– Personal interviews conducted by telephone.– The mainstay of commercial survey research.– “No-call” legislation has limited this capacity.
• Mobile Phone Interviews– In U.S., no telemarketing can be directed toward mobile
phone numbers.– Recipient of call is even more likely to be distracted.– Area codes not necessarily tied to geography.– Phones have varying abilities.
10–12
Phone Interview Characteristics• Speed
• Cost
• Absence of face-to-face contact
• Cooperation
• Incentives to respond
• Representative samples
• Callbacks
• Limited duration
• Lack of visual medium
10–13
Types of Telephone Interviews
• Central Location Interviewing– Conducting interviews from a central location allowing firms to hire a
staff of professional interviewers and to supervise and control the quality of interviewing more effectively.
• Computer-Assisted Telephone Interviewing (CATI)– Allows answers to telephone interviews to be entered directly into a
computer for processing.
• Computerized Voice-Activated Telephone Interview– Combining computerized telephone dialing and voice-activated
computer messages to allow researchers to conduct telephone interviews without human interviewers.
10–14
Telephone Interview Recap• Speed of data collection: very fast• Geographical flexibility: high• Respondent cooperation: good• Versatility of questioning:
moderate• Questionnaire length: moderate• Item nonresponse: medium• Possibility of respondent
misunderstanding: average• Degree of interviewer influence
of answer: moderate
• Supervision of interviewers: high, especially with central location interviewing
• Anonymity of respondent: moderate
• Ease of call back or follow-up: easy
• Cost: low to moderate
• Special features: fieldwork and supervision of data collection are simplified; quite adaptable to computer technology

EXHIBIT 10.1 Self-Administered Questionnaires Can Be Either Printed or Electronic
10–16
Mail Questionnaires
• Characteristics of Mail Questionnaires– Geographical flexibility– Cost– Respondent convenience
– Anonymity of respondent
– Absence of interviewer
– Standardized questions
– Time is money
– Length of mail questionnaire10–17
Self-Administered Questionnaires
• Response Rate– The number of questionnaires returned or
completed divided by the number of eligible people who were asked to participate in the survey.
• Factors that Bias the Response Rate– Persons who will complete questionnaires versus
those persons who will not.– Person filling out survey is not the intended subject.
10–18
Increasing Response Rates for Mail Surveys• Cover letter• Money helps• Interesting questions• Follow-ups• Advance notification• Survey sponsorship• Other techniques• Keying mail questionnaires
with codes

Fax Surveys
• A survey that uses fax machines as a way for respondents to receive and return questionnaires.
• Advantages– Reduce sender’s printing and postage costs– Is quicker than traditional mail surveys
• Disadvantage– Only respondents with fax machines who are willing
to exert the extra effort will return questionnaires.
10–22
E-Mail Surveys • Surveys distributed through electronic mail.• Ways to contact respondents:
– Include a questionnaire in the body of an e-mail.– Distribute questionnaire as an attachment.– Include a hyperlink within the body of an e-mail.
• Advantages– Speed of distribution– Lower distribution and processing costs– Faster turnaround time– More flexibility– Less handling of paper questionnaires
• Disadvantage– Not all e-mail systems have the same capacity
10–23
Internet Surveys• A self-administered questionnaire posted on
a Web site. – Respondents provide answers to questions
displayed online by highlighting a phrase, clicking an icon, or keying in an answer.
10–24
Internet Survey Characteristics
• Speed and cost effectiveness
• Visual appeal and interactivity
• Respondent participation and cooperation
• Representative samples• Accurate real-time data
capture
• Callbacks• Personalized and flexible
questioning• Respondent anonymity• Response rates• Security concerns
10–25
Other Approaches• Kiosk Surveys
– Placed in high-traffic locations (e.g., airports).
• Mixed-Mode Survey Research– Employs any combination of survey methods.
• Text-Message Surveys– May use SMS (short-message service) or MMS
(Multi-Media Service).
10–26
Selecting the Appropriate Survey Approach
• Questions to be answered:– Is the assistance of an interviewer necessary?– Are respondents interested in the issues being
investigated?– Will cooperation be easily attained?– How quickly is the information needed?– Will the study require a long and complex
questionnaire?– How large is the budget?
10–27
Pretesting Survey Instruments• Pretesting
– Screening procedure that involves a trial run with a group of respondents to iron out fundamental problems in the survey design.
• Basic Ways to Pretest:– Screen the questionnaire with other research
professionals.– Have the client or the research manager review the
finalized questionnaire.– Collect data from a small number of respondents.
10–28
Ethical Issues in Survey Research
• Many ethical issues apply to survey research:– Respondents’ right to privacy– Use of deception– Respondents’ right to be informed– Need for confidentiality– Need for honesty in collecting data– Need for objectivity in reporting data
