CHAPTER 1
INTRODUCTION
SUMMARY
Statistics: A Tool for Social Research, Fifth Canadian Edition, 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 consistently presents statistics in the
context of the research enterprise; that is, statistics are always presented not as ends in
themselves, but as useful devices or tools for answering questions and testing theories.
The chapter also distinguishes between descriptive and inferential statistics, and between
univariate, bivariate, and multivariate statistics. The distinction between discrete and continuous
variables and the concept of level of measurement are presented as well. The latter is stressed
throughout the text as an organizational device and as a 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.
NEW TO THE FIFTH CANADIAN EDITION
The “You are the Researcher” section has been updated with new survey data, the 2018 GSS and
CCHS.
WHAT CAN I DO IN CLASS?
1. Provide students with a table consisting of a variable (Column 1), the variable’s response
categories (Column 2), whether it is independent or dependent (Column 3), and the level
of measurement (Column 4). Ask students to identify the variables as independent or
dependent, as well as the level of measurement for each given variable. Go over the
answers in class. For example, gender is an independent nominal-level variable and
health is a dependent variable measured at either the interval-ratio (body weight in
kilograms), ordinal (poor, good, or excellent self-rated health), or nominal (have a family
doctor, yes or no) level.
2. Show a list of examples of populations and samples, and have students identify each as
such. For example, we want to know if more male students or more female students visit
the local pub on campus in a given week.
a. Sample: The number of male and female visitors you observe visiting during a
one-hour period
b. Population: Everyone who visits the local pub on campus in a given week
