The material in this user-friendly text is presented as simply as possible to ensure that students will gain a solid understanding of statistical procedures and analysis.
The goal of this book is to demystify and present statistics in a clear, cohesive manner. The student is presented with rules of evidence and the logic behind those rules. The book is divided into three major units: Descriptive Statistics, Inferential Statistics, and Advanced Topics in Inferential Statistics.
Every effort has been made to keep the writing as clear as possible and always aimed at the student's life space. Computational procedures are laid out in a step-by-step, programmed format. This is a straightforward presentation of the essentials of statistical analysis emphasizing the constant interaction between statistical techniques and the resarch methodology.
Written in an easy-to-read, engaging literary style with many new and interesting examples to hold student interest.
- Includes definitions of key concepts in the glossary to prevent student confusion over terminology.
- Provides a convenient summary at the end of each chapter to reinforce learning.
- Numerous problems and test questions throughout the text allow students to apply what they have learned.
- Introduces students to the language of research methodology and the basics of research reasoning (Ch. 9) prior to commencing work on any inferential techniques, such as the independent t or Pearson r.
- Provides methods for finding percentiles in Chapter 5.
- Can be packaged with SPSS Student Version CD-ROM for an additional cost.
There are some major additions and deletions for this edition.
- A new unit which covers the issue of the lack of homogeneity of variance.
- New sections covering research issues and strategies in the area of criminal justice.
- Inclusion of smaller data sets for students to practice.
- Research examples have been updated and carefully chosen for student interest as well as pedagogical purposes.
- A new section, the statistical Rosetta Stone, illustrates all of the statistical symbols in the book for a quick reference for students.
