Discovering Statistics, 3e Features
The Big Picture
A brief, bulleted list at the beginning of each chapter reminds students what they learned in the previous chapter, introduces them to the major concepts explored in the current chapter, and offers a glimpse into the next chapter. This feature helps students connect key themes across chapters and outlines the logical progression of the text.
Each section begins with a list of numbered
headed "By the end of this section, I will be able to . . .". The objective numbers are matched with the numbered topics within each section as well as the end-of-section summary.
Now You Can Do
Found in the margin next to most examples,
Now You Can Do
cues students to try related "Practicing the Techniques" exercises, prompting them to try the techniques shown in the example. When working a particular exercise, students can easily look back through the section to find the callout to a related example.
exercises follow about half of the examples. Students can use these exercises to self-test or instructors can use them in class to further reinforce concepts. Answers to all "Your Turn" exercises are included in Appendix A.
Bringing It All Together
Exercises within each section offer a culmination of everything you have learned in a particular section, using a related set of “Applying the Concepts” exercises to tie together the main concepts and techniques learned.
Available in a variety of software formats, each
is named and marked with an icon in the text, which can be found online at
What Does This Mean?
This feature box fosters an intuitive approach and interpretation of results. Whenever a new formula or statistic is being introduced, developing an understanding of, “What does this really mean?” is just as important as getting the right answer. This feature helps to implement the GAISE guideline “Stress conceptual understanding.”
What Results Might We Expect?
This feature, located in example solutions, challenges students to predict what the result of a particular problem will be. Students are presented with a graphical view of the situation and, before performing any calculations, are asked to bring their intuition and common sense to bear on the problem and to state, “what results we might expect” once the numbers are crunched.
