Statistical Methods for Psychology 4th Edition || David C. Howell

Intended for graduate-level courses in statistics for psychology majors, this best-seller has earned high marks among students and instructors for its clear, conceptual approach and strong emphasis on experimental psychology. The author presents statistics at an intuitive level to give students a sense of how tests work and how they interrelate. Stressing the value of data analysis before jumping in with a hypothesis test, Howell examines the connection between statistical tests and the theoretical questions posed by such experiments to develop students' conceptual skills.
