is to collect primary data—data gathered from the
respondents and assembled specifically for the project at hand.
SURVEY RESEARCH
- People who verbally answer an interviewer’s questions or provide answers to
written questions.
Respondents
– a more formal term, which emphasizes that the purpose of contacting
respondents is to obtain a representative sample, or subset, of the target population.
Sample Survey
- A statistical fluctuation that occurs because of chance variation in
the elements selected for a sample.
Random Sampling Error
- A persistent tendency for the results of a sample to deviate in one direction
from the true value of the population parameter.
Sample Bias
The many sources of error that in some way systematically influence answers can be divided
into two general categories:
respondent error and administrative error.
- A category of sample bias resulting from some respondent action or
inaction such as nonresponse or response bias.
Respondent Error
- The statistical differences between a survey that includes only
those who responded and a perfect survey that would also include those who failed to
respond.
Nonresponse Error
- People who are not contacted or who refuse to cooperate in the
research.
Non Respondents
- People who are not at home or who are otherwise inaccessible on the
first and second contact.
No Contacts
- People who are unwilling to participate in a research project.
Refusals
- A bias that occurs because people who feel strongly about a
subject are more likely to respond to survey questions than people who feel indifferent about
it.
Self-Selection Bias
- A bias that occurs when respondents either consciously or unconsciously
tend to answer questions with a certain slant that misrepresents the truth.
Response Bias
A response bias may occur when people misrepresent answers to appear
intelligent, conceal personal information, avoid embarrassment, and so on.
Deliberate
Falsification -
- Even when a respondent is consciously trying to be
truthful and cooperative, response bias can arise from the question format, the question
content, or some other stimulus.
Unconscious Misrepresentation
Type of Response Bias (4)
Acquiescence Bias -
Extremity Bias
Interviewer Bias
Social Desirability Bias
A tendency for respondents to agree with all or
most questions asked of them in a survey.
Acquiescence Bias -
A category of response bias that results because
some individuals tend to use extremes when responding to questions.
Extremity Bias -
A response bias that occurs because the
presence of the interviewer influences respondents’ answers.
Interviewer Bias -
- Bias in responses caused by respondents’
desire, either conscious or unconscious, to gain prestige or appear in a
different social role.
Social Desirability Bias
- An error caused by the improper administration or execution of the
research task.
Administrative Error
- A category of administrative error that occurs because of
incorrect data entry, incorrect computer programming, or other procedural errors during
data analysis.
Data-Processing Error
- An administrative error caused by improper sample design
or sampling procedure execution.
Sample Selection Error
Mistakes made by interviewers failing to record survey responses correctly.
interviewer error -
- The practice of filling in fake answers or falsifying questionnaires
while working as an interviewer.
interviewer cheating
- A question that imposes a limit on the number of allowable
responses.
Structured Question
- A question that does not restrict the respondents’ answers.
Unstructured Question
- Straightforward questions that assume the respondent is willing to
answer.
Undisguised Questions
- Indirect questions that assume the purpose of the study must be
hidden from the respondent. Temporal Classification
Disguised Questions
- A study in which various segments of a population are sampled and
data are collected at a single moment in time.
Cross-Sectional Study
- A survey of respondents at different times, thus allowing analysis of
response continuity and changes over time.
Longitudinal Study
- A type of longitudinal study that uses successive samples to
compare trends and identify changes in variables such as consumer satisfaction, brand
image, or advertising awareness.
Tracking Study
- A longitudinal survey of the same sample of individuals or
households to record their attitudes, behavior, or purchasing habits over time.
Consumer Panel
Face-to-face communication in which an interviewer asks a respondent to answer questions.
Personal Interviews
Advantages of Personal Interviews ✓ Opportunity for Feedback (5)
✓ Probing Complex Answers
✓ Length of Interview
✓ Completeness of Questionnaire
✓ Props and Visual Aids
✓ High Participation
Disadvantages of Personal Interviews (3)
✓ Interviewer Influence
✓ Lack of Anonymity of Respondent
✓ Cost
- Personal interviews conducted at respondents’ doorsteps in an
effort to increase the participation rate in the survey.
Door-to-Door Interviews
Personal interviews conducted in a shopping mall.
Mall Intercept Interviews -
- Attempts to recontact individuals selected for a sample who were not available
initially.
Callbacks
- Personal interviews conducted by telephone, the mainstay of
commercial survey research.
Telephone Interviews
Mobile phone interviews differ from landline phones most
obviously because they are directed toward a mobile (i.e., cell) phone number. However,
there are other less obvious distinctions
Mobile Phone Interviews -
Phone Interview Characteristics (9)
✓ Speed
✓ Cost
✓ Absence of Face-to-Face Contact
✓ Cooperation
✓ Incentives to Respond
✓ Representative Samples
✓ Callbacks
✓ Limited Duration
✓ Lack of Visual Medium
- Telephone interviews conducted from a central location
allowing firms to hire a staff of professional interviewers and to supervise and control the
quality of interviewing more effectively.
