Noted for its clear, concise, and statistically accurate discussions, Johnson's Statistics: Principles & Methods, 4th Edition constantly probes beyond the procedures to teach the reader the reasoning behind a method. The authors discuss the assumptions that all statistical models make and motivate discussions using real-life examples. By means of good motivation, sound explanations, and an abundance of illustrations given in a real-world context, this book emphasizes more than just a superficial understanding of the material.
