This book is a must read for statistics student or teachers at any level and speaks directly to the "I just don't' get it" thought that so many of have experienced. After reading this book-you will get it. In a casual and easy to read manner, Vickers reviews statistical concepts and ideas that have puzzled students for years and explains them in a way that is easy to grasp.
What is a p-value Anyway? offers a fun introduction to the fundamental principles of statistics, presenting the essential concepts in thirty-four brief, enjoyable stories. Drawing on his experience as a medical researcher, Vickers blends insightful explanations and humor, with minimal math, to help readers understand and interpret the statistics they read every day.
What is a p-value Anyway? is the perfect complement to any introductory statistics textbook and will succeed in demonstrating the everyday importance of statistics to your class. When I started writing this book, I wondered whether I could write something about statistics that was fun, at least in places.
This is how I came up with the idea of stories; you hear a story to help you understand something and you'll remember it for life. Hopefully, after you have read this textbook, you'll have a good understanding of many of the key ideas of statistics. You'll also be able to avoid making some of the most common statistical mistakes and errors.
Describing data; Data distributions; Variation of study results: confidence intervals; Hypothesis testing; Regression and decision making; Some common statistical errors, and what they teach us
For all readers interested in statistics.
