**is a core text for use in introductory and advanced undergraduate statistics courses in Psychology. In contrast with texts that base their approach on null hypotheses significance testing, Rick Gurnsey provides an alternative approach, one that emphasizes estimation (confidence intervals, effect sizes, and practical significance), a general approach that is more intuitively grasped by students. Built on the same statistical foundations as traditional approaches to the content, this text covers both decision making (e.g., are two population means identical or not?), and estimation (e.g., how big is the difference between two population means?). By covering both approaches, instructors are able to easily shift the emphasis from the more tradition null hypothesis significance testing to estimation.**
