Asbury Psychology Professor Publishes Statistics Textbook for Undergraduate Students

January 14, 2025

In October 2024, Dr. Paul Nesselroade ’89, professor of psychology at Asbury University, published the third edition of his textbook, now titled Essentials of Behavioral and Social Science Statistics. This streamlined, thoughtfully reimagined version helps undergraduate students understand statistical principles while critically reflecting on the history and ethics of scientific research.

“The new edition focuses on the essentials — everything a student needs to grasp statistical applications in a single 16-week semester,” Nesselroade said. “It’s leaner but also richer in key ways.”

This edition stands out with its emphasis on philosophical context. The first chapter opens with questions about the purpose and ethical dimensions of statistical analysis. By blending reflection and practical applications, the textbook offers undergraduates a distinctive learning experience.

“Statistics textbooks often focus solely on formulas and techniques,” Nesselroade said. “I wanted to address the ‘why’ of what we do, not just the ‘how.’” 

The book also introduces a series of sidebar features addressing the replication crisis in the sciences. These sections examine how pressure to publish groundbreaking findings often compromises scientific rigor. 

“In fields like psychology, medicine, and pharmacology, up to one in three studies fail to replicate,” Nesselroade noted. “This is a serious blemish on the scientific enterprise, and students must understand the broader implications of these shortcomings.”

The sidebars also profile prominent statisticians like Karl Pearson, who developed the chi-squared test but also advocated for eugenics. By presenting these figures in their historical contexts, Nesselroade encourages students to think critically about the moral responsibilities of scientists.

Nesselroade’s passion for statistics intertwines with his broader academic focus. “The history of measuring human differences remains linked with humanity’s darkest chapters. Beginning in the late 1800s, scientists began to advocate for the management of human affairs for economic and community health reasons; a eugenics crusade, led by scientists and statisticians, worked hard to exert control over human mating. Students need to understand not just how to conduct research but why they are doing it and for what purpose.”

Nesselroade wants the textbook to inspire students to think critically and contextually about data collection and analysis. “This book isn’t just about passing a stats course,” he emphasized. “It equips students to engage with the world as thoughtful, ethical contributors to science and society.”

Classrooms will adopt the book this spring, offering students a fresh approach to statistics. As Nesselroade prepares for his 11th student trip to Germany and Poland this May — exploring the psychological dimensions of the Holocaust — he also works on a companion project: a collection of essays inspired by these trips that connect historical locations with psychological insights and reflections.

“Ultimately, both projects address the same goal: understanding human behavior, with all its beauty and all its brokenness,” he said. 

The Asbury University Psychology Department offers a major and minor in Psychology, with major emphases in Business Psychology, Biological Psychology, Child Psychology, Christian Counseling/Psychology, Clinical/Counseling Psychology, Equine Facilitated Mental Health, Forensic Psychology, Social Psychology, and Student Development Psychology.
