This manual introduces undergraduates to resources and data analysis methods for studying judicial behavior and constitutional law. It contains 12 exercises, most of which are based on outside reading and analysis of data provided in appendices. Exercise one introduces the basic tools and methods for research in a law library, emphasizing use of the "Corpus Jures Secundum,""Shepard's Citations," and the "Index to Legal Periodicals." Exercise two discusses fundamentals for reading and briefing a case, and for understanding and organizing a court opinion. Exercise three explores the relation of established rules of law to the values and attitudes of the community or culture in which they have developed. Exercises four through six examine the relationship between judges' background characteristics, such as religion or party affiliation, and their judicial decisions. Data from voting records provide the basis for these exercises. Various data analysis methods are explained in exercises seven through 12. These include construction and use of Guttman scales, bloc analysis matrices, and a voting power index. These methods are useful in determining how a specific judicial decision compares to others, and how much influence one member of a voting body has in comparison to other members of the same body.
