Xiong Jian: public information is limited, and the available details come mainly from works published under this name. Two titles are held in the collection, both centered on principles of statistics: Principles of Statistics (Eighth Edition) and Principles of Statistics. The common category is exam preparation. Judging from these works, the writing is aimed at basic teaching and exam review in statistics, with content organized around fundamental concepts, methods, and principles. The existence of a revised edition suggests the material has been updated over time to meet teaching and test-preparation needs. The target readers are students studying statistics and candidates preparing for examinations, who may use the books for coursework and revision. Beyond the signed works and category information, reliable records of the author's personal background, nationality, dates of birth and death, and academic experience are lacking, so this profile makes no speculation; readers may consult the textbooks themselves to understand the author's approach and knowledge framework.
