CHAPTER SUMMARY
Sociologists are committed to the use of the scientific method in their research. The basic steps in the scientific method are defining the problem, reviewing the literature, formulating the hypothesis, selecting the research design, and collecting and analyzing the data. Finally, the researcher develops a conclusion based on the findings of the research.
An operational definition is an explanation of an abstract concept that allows a researcher to assess or measure the concept. A review of the relevant literature helps to refine the problem and reduce avoidable mistakes. A hypothesis is a speculative statement about the relationship between two or more variables. Variables are measurable traits or characteristics that are subject to change under certain conditions. The variable hypothesized to cause or influence another variable is called the independent variable. The variable that is changed or dependent on the independent variable is called the dependent variable. A correlation exists when a change in one variable coincides with a change in the other. Correlation should not be confused with causation. Causal logic involves the relationship between a condition or variable and a consequence, with one event leading to the other. Causation cannot be determined simply from correlation alone.
In most studies, social scientists carefully select a sample. A sample is a selection from a larger population that is statistically representative of the population. In a random sample, every member of the population being studied has the same chance of being selected for the study.
The scientific method requires both validity and reliability. Validity refers to the degree to which a measure or scale truly reflects the phenomenon under study. Reliability refers to the extent to which a measure produces consistent results. Sociological studies sometime fail to support the original hypothesis and researchers must reformulate their conclusions. Control variables are those factors that are held constant to test the strength of a relationship between the independent and dependent variables.
A research design is a detailed plan or method for obtaining or collecting data. Surveys are a common method of quantitative research used by researchers to collect data. Surveys may consist of oral interviews or written questionnaires. Ethnography is the study of an entire social setting and way of life through extended systematic observation. Observation is the basic technique of ethnography although the ethnographic approach is often combined with other methods such as interview. Observation is a qualitative research method, which allows researchers to collect data through everyday interaction with a group or community under study. Experiments are artificially created situations in which researchers can manipulate variables. Typically, an experimental group is exposed to the independent variable and the control group is not. Analyzing existing data that has been previously collected is called secondary analysis. Content analysis involves the systematic coding and objective recording of data, such as using newspapers, periodicals, and other common documents or venues to interpret and test the significance of data. All researchers must abide by a code of ethics to ensure that researchers are not causing harm or violating a person’s privacy. Most research seeks to remain value neutral in its judgments when interpreting research results. However, some have suggested neutrality may be impossible to attain. As the feminist perspective gains influence among sociological researchers, feminist methodology is changing both how issues are defined and how data is collected. Computers and the Internet are exciting technologies that are having an impact on research.

LECTURE OUTLINE
I. What Is the Scientific Method?
• A systematic, organized series of steps that ensures maximum objectivity and
consistency in researching a problem.
• Requires precise preparation in developing useful research; otherwise, the research data
collected may not prove accurate.
A. Defining the Problem
• An operational definition is required to assess the concept. Example: using
membership in exclusive social clubs as an operational definition of status.
B. Reviewing the Literature
• Refines the problem under study, clarifies data collection techniques, and
eliminates or reduces avoidable mistakes.
C. Formulating the Hypothesis
• Hypothesis: A speculative statement about the relationship between two or more
variables (a measurable trait or characteristic).
• Independent variables cause or influence change in dependent variables.
• Dependent variables are changed by the independent variables or are dependent
of them.
• Causal logic refers to the relationship between a condition or variable and a
particular consequence, with one event leading to the other. Example: Time
spent studying may result in a higher grade on an exam.
• Correlation is an indication that causality may be present.
D. Collecting and Analyzing Data
• Research designs guide researchers in collecting data.
1. Selecting the Sample
• Sample: a statistically representative selection from a larger population.
• A random sample occurs when every member of an entire population
has the same chance of being selected for the study.
2. Ensuring Validity and Reliability
• Validity refers to the degree to which a measure or scale accurately
reflects the phenomenon under study.
• Reliability refers to the extent to which a measure produces consistent
results.
E. Developing the Conclusion
• Conclusion represents both an end and a beginning in research.
1. Supporting Hypothesis
• Some studies refute a hypothesis, which leads to reformulations about a
conclusion and adjustments in research designs.
2. Controlling for Other Factors
• A control variable is a factor held constant to test the relative impact of
the independent variable. Example: surveying attitudes of smokers and
nonsmokers.
F. In Summary: The Scientific Method
• The data support the hypothesis that education level influences income.
II. Major Research Designs
• A detailed plan or method for obtaining data scientifically.
A. Surveys
• Generally in the form of an interview or questionnaire, providing researchers
with information about how people think or act. Example: Gallup poll.
• The survey is an example of quantitative research, which collects and reports
data primarily in numerical form.
• Skillful interviewers can go beyond written questions and probe a subject’s
underlying feelings; questionnaires have the advantage of being cheaper to
administer.
B. Observation
• Qualitative research offers more depth and detail than quantitative analysis.
This type of research relies on what is seen in field and naturalistic settings,
and often focuses on small groups and communities. Observation is the most
common form. Example: studying gangs, or service organizations.
• William F. Whyte’s work is a classic example of participant observation
research, when he moved into a low-income Italian neighborhood in Boston
(1930s).
• Ethnography: The study of an entire social setting through extended systematic
observation. The Adlers’ study of self-injury, described in the
chapter opening, was an ethnographic study.
C. Experiments
• Artificially created situation. Typically involves the use of an experimental
group exposed to an independent variable, and a control group, which is not
exposed to the independent variable.
• Sociologists do not rely on classic forms of experiment/control groups, due to
the danger they might cause to humans.
• Hawthorne effect refers to subjects of research who deviate from typical
behavior because they are under observation.
D. Use of Existing Sources
• Secondary analysis refers to making use of previously collected or publicly
accessible information and data. Example: Census data.
• Existing data is nonreactive, since it does not influence people’s behavior; thus,
researchers can avoid the Hawthorne effect by using secondary analysis.
Example: Durkheim’s research on suicide.
• Content analysis is the systematic coding and objective recording of data.
Example: Analyzing the content of films to determine if there has been an
increase in the depiction of smoking in movies.
III. Ethics of Research
• Code of Ethics, ASA first published in 1971.
• Objectivity, integrity, privacy, protection from harm, confidentiality, informed consent,
acknowledge collaboration and assistance, and disclose sources of financial support.
A. Confidentiality
• Rik Scarce jailed for refusing to divulge what he knew about a 1991 raid on a
university lab by animal rights activists.
• The Supreme Court has failed to clarify the rights of scholars preserving the
confidentiality of research subjects.
B. Research Funding
• When accepting funding for their research, sociologists must be careful that the
funding source does not taint the objectivity of the research. Example: Exxon
funded research on jury deliberations after the Valdez disaster.
C. Value Neutrality
• Weber and value neutrality in research. Neutrality may be impossible.
IV. Feminist Methodology
• Impact of feminist perspective on current researchers. Example: Research now being
conducted on integration of work and family, rather than viewing the two topics as
unrelated.
• Historically, sociologists researched men’s work, associations, communities, and
generalized this research to all people, resulting in a biased picture of social life.
• Frequently employs a multidisciplinary approach to the research itself and its
application.
V. Technology and Sociological Research
• Impact of computers and Internet on research. Example: Software programs.
• Web-based surveys are promising, but may not be random samples.
