The goal of this book is to introduce you to the many ways that statistics can be used to solve practical, real world problems. Examples deal with topics as varied as valuating mental health treatment facilities, testing new drugs, valuating the likelihood of a convicted criminal’s reoffending after parole, hiring the best personnel, evaluating trends in waste (trash) production and more. This book will show you how to: Identify applicants who would make the best employees. Develop and test marketing campaigns to find out which ones work best. Help political candidates and others know how the public is feeling about something (you may be surprised that this is more involved than simply asking a bunch of people what they think!) Design control panels, dash boards and work spaces that help people perform at their maximum efficiency. Identify and predict who will make the best athletes. Confirm that all products produced in a factory conform to the same high standards (how would you like that job…beer tester?). Decide which new flavor of ice cream would be most accepted by the public (I want that job!) Determine whether a new medication is effective and what the appropriate dosage should be. And the list goes on and on and on! Statistics are the life blood of modern business management. Virtually everything in science is based on statistical analysis. But, to many people, statistics are as scary as a Halloween Ghost. Are you and math not the best of friends? Have you tried to take a statistics class but found it so confusing you dropped it? Has it been so long since you have taken a statistics class that you don't know a t-test from a Phi Coefficient? Do you need to develop a better understanding of analytical and statistical tools to advance in your career? If any of these questions sound like you, The Radical Statistician may be just what you are looking for. The Radical Statistician was written as a textbook for an introductory course in applied statistics for the behavioral sciences. The goal was to develop a book that captured the fun, power and financial benefit that comes with the knowledge of how to use statistics to solve real world problems.
