Wang Shufen: publicly available information is limited, and at present only one work by this author, Applied Statistics (3rd Edition), is known to be included. The book is classified under exams, indicating that its compilation is closely tied to exam preparation, course study, or review for related assessments. Judging from the title, the work should cover the basic concepts, methods, and practical applications of applied statistics; the fact that it is a third edition also suggests that the book has been revised and improved, giving it a degree of continuity among similar study materials. Such textbooks generally emphasize clear organization of knowledge points and practicality, making it easy for readers to study chapter by chapter and consolidate what they have learned through exercises and review. Because explicit information about the author's life, positions, and research direction is lacking, it is not appropriate to infer their educational background or academic experience; readers may instead rely on the book's chapter arrangement and exercise design to understand the author's approach to popularizing statistical knowledge and supporting exam preparation.
