Chapter 9 Summary
Explain
the advantages and disadvantages of using quantitative,
descriptive survey research designs to collect primary raw
data.
Some of the main advantages of using survey designs to collect
primary raw data from respondents are ability to accommodate
large sample sizes' generalizability of results; ability
to distinguish small differences between diverse samples
groups; ease of administering and recording questions and
answers; increased capabilities of using advanced statistical
analysis; and abilities of tapping into latent factors and
relationships. In contrast, the main disadvantages of survey
research designs tends to focus on potential difficulties
of developing accurate survey instruments; inaccuracies
in construct and scale measurements of factors; and limits
to the depth of the data structures. In addition, researchers
can lack control over long time frames and potentially low
response rates, among other problems.
Discuss
the many types of survey methods available to researchers.
Identify and discuss the factors that drive the choice of
survey methods.
Survey methods are generally divided into three generic
types. One is the person-administered survey, in which there
is significant face-to-face interaction between the interviewer
and the respondent. Second is the telephone-administered
survey. In these surveys the telephone is used to conduct
the question-and-answer exchanges. Computers are now used
in many ways in telephone interviews, especially in management
functions, data recording, and telephone-number selection.
Third is the self-administered survey. In these surveys,
there is little, if any, actual face-to-face contact between
the researcher and prospective respondent. The respondent
reads the questions and records his or her answers. Most
of the emerging technology survey methods are self-administrated,
although some, such as virtual reality, will require human
intervention.
There are three major factors affecting the choice of survey
method: situational characteristics, task characteristics,
and respondent characteristics. With situational factors,
consideration must be given to such elements as available
resources, completion time frame, and data quality requirements.
Also, the researcher must consider the overall task requirements
and ask questions like, "How difficult are the tasks?,"
"What stimuli will be needed to evoke responses?,"
"How much information is needed from the respondent?,"
and "To what extent do the questions deal with sensitive
topics?" Finally, the researchers must be concerned
about the diversity of the prospective respondents, the
likely incidence rate, and the degree of survey participation.
Maximizing the quantity and quality of data collected while
minimizing the cost and time of the survey generally requires
the researcher to make trade-offs.
Explain
how the electronic revolution is affecting the administration
of survey research designs.
With the increasing advances in telecommunication and computer
technologies, numerous new, fast techniques are available
to researchers for collecting primary raw data from people.
The range of new techniques continues to grow and includes
such methods as computer-assisted telephone interviewing
methods; fully automated self-administered techniques; and
electronic mail, fax, and Internet surveys. There is little
doubt that the time requirements of collecting data will
significantly decrease with these new methods.
Identify
and describe the strengths and weaknesses of each type of
survey method.
It is important to remember that all methods have strengths
as well as weaknesses. No single method is the best choice
under all circumstances. Nor is the information researcher
limited to a single method. Innovative combinations of survey
methods can produce excellent results, as the strengths
of one method can be used to overcome the weakness of another.
Identify
and explain the types of errors that occur in survey research.
The researcher needs to evaluate the errors in the research
results. All errors are either random sampling errors or
nonsampling errors. By far the greatest amount of error
that can reduce data quality comes from nonsampling (or
systematic) error sources. Three major sources of error
are respondent error (i.e. nonresponse errors and response
biases); measurement and design error (i.e., construct development,
scale measurement, and survey instrument design errors);
and administrative errors (i.e., data processing, interviewer
and sample design errors). In survey research, systematic
errors decrease the quality level of the data being collected.
