Title overview
Invigorate learning with the Enhanced Pearson eText
The Enhanced Pearson eText provides a rich, interactive learning environment designed to improve student mastery of content with the following multimedia features:
- Embedded Flashcards. Readers can review key terms. (See page 44 and 82 for examples.)
- Chapter Review. Readers can check their understanding of chapter concepts by completing of chapter reviews. (See page 44 and 83 for examples.)
- Interactive Learning Objectives at the beginning of each chapter. (See page 1 and 65 for examples.)

Additional text features include:
- Incorporates Real-life Examples - Major statistical tests presented throughout the text are accompanied by real-life examples. These examples show students how statistical analysis can be used in social work practice decision-making. New and revised case examples such as ethical considerations of central tendency and dispersion (Chapter 3), illustrate how statistical analysis can be used in day-to-day decision-making, as well as in basic research.
- De-emphasizes Mathematical Computations - Mathematical computations are de-emphasized, helping students to focus on understanding the importance of statistical analysis and apply the results to social work practice.
- Provides Visual Explanations - Numerous boxes, figures and tables summarize key sections and help students to comprehend some of the more abstract ideas presented.
- Addresses Ethical Issues - Potential ethical problems in the use of statistical analyses are identified, and suggestions are offered as to how they can be avoided.
- Connects Statistics and Research Design - The inter-relationship of statistics and research design is emphasized throughout, both in a new “Research Design” section in Chapter 1 and when each statistical test is discussed. The book describe how certain research designs and certain statistical analyses "go together."

Key content changes include:
Correlated with the Council on Social Work Education (CSWE) Competencies.
Chapter 1
- Completely rewritten and reorganized
- A new section on research design
- Additional content on construction of dummy variables
- New content on the relationship between research hypotheses and statistics
- New content on null research findings and their value
- Increased emphasis on the use of statistics in descriptive research.
Chapter 2
- New content on computer generated graphs and the ethical issues they present
Chapter 3
- More content on measures of central tendency and dispersion, with new examples of how (ethically) to decide which to use
Chapter 4
- New content on sampling error and its relationship to research design
Chapter 5
- Increased emphasis on the role of the null hypothesis in statistics, and how the laws of probability are used
Chapter 6
- Content on sampling distributions has been re-organized and re-written for improved clarity.
Chapter 7
- A new section explaining the (often misunderstood) concept of degrees of freedom
- The various t-tests and ANOVA are now presented with a listing of the research designs with which each is most often used
Chapter 8
- New content on the meaning of each of the numbers in a cross-tabulation table
- More content on degrees of freedom and the various research designs where the chi-square test can be used
Chapter 9
- Correlation analysis is described as very versatile; it's use in both research design and hypothesis testing is described
- There are numerous new and previously used examples of how correlation can be misinterpreted if it is confused with causation
Chapter 10
- Examples of how regression analysis can be used for making everyday practice decisions
Chapter 11
- There is new and expanded description of meta-analysis with new examples
- A new box and a new figure support and clarify a new section on logic models and how they provide the focus for the statistical analysis that is used in different types of program evaluations
