For the first course in Statistics, the Second Edition of Statistics for Psychology capitalizes on a successful approach which presents statistics through definitional formulas to emphasize conceptual understanding, not rote memorization. Presenting statistical methods as a living, growing field of research, the book highlights recent controversies and developments. Thoroughly revised with new content and many new examples, the text takes the student from basic procedures through analysis of variance (ANOVA), and in a unique concluding chapter introduces the general linear model to integrate all of the statistical procedures presented. Better than any other text, Statistics for Psychology not only teaches statistics, but prepares students to read and understand research articles.
