3. Chapter Preview 1 Chapter Preview · Section 1 Research Methods (pages 38–49) When sociologists do quantitative research, they generally use either surveys or precollected data. Each has its own advantages and disadvantages. Field studies are best used when interaction needs to be observed in a natural setting, and when in- depth analysis is needed. The case study is the most popular approach to field research.

4. Chapter Preview 2 Chapter Preview · Section 2 Causation in Science (pages 50–57) Causation in science is the idea that one event leads to another event. Scientists assume that all events have causes, or determinants. Sociologists work to discover these causes. Three standards must be met before causation can be proved.

5. Chapter Preview 3 Chapter Preview · Section 3 Procedures and Ethics in Research (pages 58–62) The research process is made up of several distinct steps. These steps represent an ideal for scientific research. It is not always necessary or even possible that they always be strictly followed. Researchers have an ethical obligation to protect participants’ privacy and to avoid deceiving or harming them. Preserving the rights of subjects is sometimes weighed against the value of the knowledge to be gained.

7. Section 1-Preview When sociologists do quantitative research, they generally use either surveys or precollected data. Each has its own advantages and disadvantages. Qualitative research uses descriptive rather than numerical data. Field studies are best used when interaction needs to be observed in a natural setting, and when in-depth analysis is needed. The case study is the most popular approach to field research.

10. Section 1 Doing Research in the Social Sciences Sociologists must conduct research in a real- world setting as opposed to a laboratory. Sociologists rely on quantitative and qualitative research. Quantitative research uses numerical data, while qualitative research uses narrative or descriptive data, such as surveys or precollected data.

20. Section 1 Field Research (cont.) Researchers often become a member of the group being studied, either with or without the group’s knowledge (also known as participant observation). participant observation Investigating School Violence and School Funding Summary of Research Methods

22. Section 1-End

23. Section 2-Preview Causation in science is the idea that one event leads to another event. Scientists assume that all events have causes, or determinants. Social events are so complex, however, that many factors may be identified as causes. Three standards must be met before causation can be proved.

25. 1.A 2.B Section-Polling Question Can you think of any newsworthy events, good or bad, that were predictable? A.Yes B.No

26. Section 2 The Nature of Causation Causation is a concept that means that events occur in predictable, nonrandom ways.Causation Sociologists believe that an event occurs as a result of several factors working in combination, or multiple causation.multiple causation

28. Section 2 Variables and Correlations A variable is a characteristic that is subject to change.variable Quantitative variable—one that can be measured and given a numerical value.Quantitative variable Qualitative variable—one that is identified by membership in a category (“either/or” or “yes/no” category).Qualitative variable The Wired World

29. Section 2 Variables and Correlations (cont.) An independent variable causes something to occur.independent variable A dependent variable results from the change in the independent variable.dependent variable An intervening variable influences the relationship between the independent and the dependent variable.intervening variable

30. Section 2 Variables and Correlations (cont.) A correlation is a measure of how things are related to one another.correlation –Positive correlation—if both the independent and dependent variable change in the same direction. –Negative correlation—if the variables change in the opposite direction. Positive and Negative Correlations

31. A.A B.B C.C D.D Section 2 Whether a variable is dependent or independent can change depending on the situation. A.Always B.Sometimes C.Never D.Not sure

32. Section 2 Standards for Showing Causation Standard 1: Two variables must be correlated. Standard 2: All other possible factors must be taken into account; the fact that two events are correlated does not mean that one causes the other.

33. Section 2 Standards for Showing Causation (cont.) Spurious correlation is an apparent relationship between two variables that is actually caused by a third variable affecting both of the other variables.Spurious correlation Standard 3: A change in the independent variable must occur before a change in the dependent variable can occur, or the cause must occur before the effect. A Spurious Correlation

34. A.A B.B C.C D.D Section 2 Which statement best defines a spurious correlation? A.Two variables must be correlated. B.A third variable may affect the other two variables. C.A cause must occur before the effect. D.One variable causes the other to occur.

39. Section 3 Steps for Doing Research The scientific method involves the pursuit of knowledge in a systematic way. Most sociologists follow this method, but not always mechanically.scientific method Secondary Analysis: A Model for Research

40. Section 3 Steps for Doing Research (cont.) The steps are as follows: –Identify the Problem—the researcher chooses an object or topic to study. –Review the Literature—she then conducts a literature search. –Formulate Hypotheses—she forms a hypothesis, or testable statement of relationships among well-defined variables. hypothesis

41. Section 3 Steps for Doing Research (cont.) –Develop a Research Design—the researcher then states the procedures she will follow for collecting and analyzing data. –Collect Data—this involves either asking people questions, observing behavior, or analyzing existing materials and records. –Analyze Data—at this point, the researcher determines if the hypothesis can be supported.
