## Description

Emphasizing meaning and concepts, not just symbols and numbers Statistics for Psychology, 6th edition places definitional formulas center stage to emphasize the logic behind statistics and discourage rote memorization. Each procedure is explained in a direct, concise language and both verbally and numerically. Learning Goals Upon completing this book, readers should be able to: * Know both definitional and numerical formulas and how to apply them * Understand the logic behind each formula * Expose students to the latest thinking in statistical theory and application * Prepare students to read research articles * Learn how to use SPSSshow more

## Review quote

"I like the order in which the topics are presented. The order is the same way that I would choose if I were writing a text myself." - Kathleen Denson, Texas A&M Commerce "Aron et al. strives to make statistical concepts accessible to students who may not have a background or interests in math." - Brock Kirwan, Brigham Young University "This text is at a level that I would feel comfortable assigning to my intro stats students." - Osvaldo Morera, University of Texas at El Paso "I like that [the text] introduced students to more complex techniques in an effort to help them to understand the articles that they are reading with more complex statistics in them" -Stacey Williams, East Tennessee State University ".The Level of writing is it's strongest assets. Very clear step by step instructions. The level of writing is very appropriate to my students" -Stephen Armeli, Farleigh Dickinson "High-level, clear, comprehensive. The book is effective at helping students understand the material" - Kristin Lane, Bard Collegeshow more
