Introduction You May Ask Yourself Copyright © 2008 W.W. Norton & Company, Inc. 2  Research methods — standard rules that social scientists follow when trying to establish a causal relationship between social elements Quantitative methods seek to obtain information about the social world that is in, or can be converted to, numeric form. Qualitative methods attempt to collect information about the social world that cannot be readily converted to numeric form.

Introduction  Causality is the idea that a change in one factor results in a corresponding change in another factor. You May Ask Yourself Copyright © 2008 W.W. Norton & Company, Inc. 3

The Basics You May Ask Yourself Copyright © 2008 W.W. Norton & Company, Inc. 6  Causation exists when a change in one factor causes the change in the other factor. Sociologists conduct research to try to prove causation. To prove causation, correlation and time order is established and alternative explanations are ruled out.

Outcomes of a particular research study must be able to be generalized to a larger population. Researchers must be aware of the effects they have on the people, relationships, and processes they are studying.

Ethics of Social Research You May Ask Yourself Copyright © 2008 W.W. Norton & Company, Inc. 13  Researchers must meet codified standards. These are often set by professional associations, academic institutions, or research centers when conducting studies. Researchers must guard against causing physical, emotional, or psychological harm to their subjects.
