Perhaps youre taking a statistics class, or youre about to take one. You may understand some of the basic ideas, but you have questions and want a place to go for a little extra help to give you an edge. And you also want a heads-up as to what instructors really think about when they write their exams. Well, look no further; help has arrived in the form of Statistics Workbook For Dummies, 2nd Edition.

This workbook helps you become more comfortable with and confident about statistics. Through plenty of practical problems that take you from step one all the way to your final exam, you review the concepts you know, identify areas where you need to focus more work, and address the little things that can make the difference between a B and an A.

As a statistics professor who has taught tens of thousands of students over the years, I have noticed that certain problems keep cropping up and causing my pen to take points off exams over and over again. And believe me: I want nothing more than to put my red pen away. So I give you all my secrets about what professors really want you to know, the kinds of questions they ask, and the types of answers they love and hate to see (so you can avoid the latter). And I focus only on the topics that you absolutely need to know, with minimal background information.

The major objectives of this workbook are for you to understand, calculate, and interpret the most common statistical formulas and techniques; get a handle on basic probability; gain confidence with difficult statistical topics such as the central limit theorem and p-values; know which statistical technique to use in different situations (for example, when to employ what kind of confidence interval); and evaluate and pinpoint problems with studies, polls, and experiments.

Although I wrote this workbook to serve as a companion to Statistics for Dummies, 2nd Edition (also published by Wiley and written by yours truly), this workbook works quite well with any introductory statistics textbook.

You may be asking how this workbook is different from other workbooks on the shelf. Well, here are a few ways, listed in order of importance:

• Plenty of excellent practice problems to lead you down the path of examination success, chosen by me, a card-carrying member of the million statistics exam question writing and grading club. I provide all answers at the end of each chapter.
• Workspace for you to work through the problems directly in the section youre working on, so you can easily refer to your notes later when you need them.
• Not only answers, but also clear, complete explanations to go with them. Explanations help you know exactly how to approach a problem, what information you need to solve it, and common problems you need to avoid.
• A view inside a professors mind to help you determine the most popular questions, the answers we look for, and the answers that make us pull our hair out.
• Tips, strategies, and warnings based on my vast experience with students of all backgrounds and learning styles (and my grading experience).
• An example accompanying each section, directly followed by the solution. Use the example as a reference when you work the other problems.
• A focus on problem-solving skills to help you develop a problem-solving strategy when you take exams. I dont show you how I would do the problems; I help you see how you can do the problems. And believe me, theres a big difference!
