Learning Objectives: By the end of this chapter, students will be able to
1. Describe the limited but crucial role of statistics in social research
2. Distinguish between three applications of statistics (univariate
descriptive, bivariate descriptive, and inferential) and identify situations
in which each is appropriate
3. Identify and describe three levels of measurement and cite examples of
variables from each.
,Chapter Summary
The text begins by explaining the role of statistics in the research process. The discussion
is guided by the "Wheel of Science" as conceptualized by Walter Wallace (Figure 1.1).
The text always presents statistics in the context of the research enterprise. That is,
statistics are presented as useful tools for answering sociological questions and testing
social science theories, never as ends in themselves.
The chapter also distinguishes between descriptive and inferential statistics and
univariate, bivariate, and multivariate statistics. The concept of level of measurement is
presented in this chapter and is stressed throughout the text as the major criterion for
selecting statistics appropriately. Exercises are provided at the end of the chapter for
reviewing the characteristics of the three levels of measurement used in this text.
