# 1,001 Statistics Practice Problems For Dummies

This book contains 1,001 statistics problems divided into 17 chapters, organized by the major statistical topics in a first-semester introductory course. The problems basically take on three levels:

• Statistical literacy: Understanding the basic concepts of the topic, including terms and notation
• Reasoning: Applying the ideas within a context
• Thinking: Putting ideas and concepts together to solve more difficult problems

In addition to providing plenty of problems to work on in each chapter, this book also provides worked out solutions with detailed explanations, so you aren’t left high and dry if you get a wrong answer.

So you can rest assured that when you work for 30 minutes on a problem, get an answer of 1.25, and go to the back of the book to see that the correct answer is actually 1,218.31, you’ll find a detailed explanation to help you figure out what went wrong with your calculations.
