Paul M. Kellstedt’s and Guy D. Whitten’s The Fundamentals of Political Science Research provides an introduction to the scientific study of politics, supplying students with the basic tools needed to be both critical consumers and producers of scholarly research in political science. The book begins with a discussion of what it means to take a scientific approach to the study of politics. At the core of such an approach is the development of causal theories. Because there is no magic formula by which theories are developed, the authors present a series of strategies and develop an integrated approach to research design and empirical analyses that allows students to determine the plausibility of their causal theories. The text’s accessible presentation of mathematical concepts and regression models with two or more independent variables is a key component to this process, along with the integration of examples from political science and the real world to help students grasp the fundamental concepts.
