**Acclaimed for helping novice behavioral scientists hit the ground running as producers of meaningful research, this text now has been extensively revised with more than 50% new material, including current guidance on open science; transparency; replication; and quantitative, qualitative, and mixed methods reporting standards.** The book provides the conceptual knowledge and practical skills needed to bridge the gap between introductory research design and analysis courses and execution of an independent study. In a candid, conversational style, Rex B. Kline guides the reader to choose appropriate research designs and analysis options; avoid common fallacies in interpreting the outcomes of statistical tests; make informed measurement choices; screen data for problems that could yield inaccurate results; and craft effective theses, journal articles, and presentations. Revised pedagogical features include engaging examples from published studies and student theses, as well as end-of-chapter exercises with answers.
