CHAPTER 6
Research Methods
    IN THIS CHAPTER
    Summary : In their scientific study of behavior and mental processes, psychologists aim to describe, understand, predict, and explain psychological phenomena. Theories are organized sets of concepts that explain phenomena. Psychologists conduct research to answer behavioral questions. They systematically collect accurate data through a variety of carefully made observations and measurements. Scientific experiments, naturalistic observations, interviews, questionnaires, case studies, and psychological tests are some methods psychologists use to explore our personalities, values, intelligence, talents, and the effects of heredity and environment on our development. The scientific method is a set of general procedures psychologists use for gathering and interpreting data. Other researchers working independently must be able to obtain similar results using the same methods; this is called replication .
    This chapter examines research methods and statistics used to make sense of research data.
