research still shares a number of common characteristics. Regardless of field, most
research involves an investigator gathering data and performing analyses to determine
what the data mean. In addition, most social scientists use a common language in
conducting and reporting their research: researchers in psychology and management
speak of “testing null hypotheses” and “obtaining significant p values.”
The purpose of this chapter is to review some of the fundamental concepts and terms that
are shared across the social sciences. You should familiarize (or refamiliarize) yourself
with this material before proceeding to the subsequent chapters, as most of the terms
introduced here will be referred to again and again throughout the text. If you are
currently taking your first course in statistics, this chapter provides an elementary
introduction. If you have already completed a course in statistics, it provides a quick
