Liu Dingxiang is an author about whom limited public information is available; the works that can currently be verified are mainly study materials in the field of statistics. Judging from the two titles included in the library, Applied Statistics and Applied Statistics: Study Guide and Practice, his writing centers on the teaching and practice of applied statistics. The former focuses on explaining the application of statistical methods, while the latter provides guidance and exercises to accompany the course, helping readers consolidate their knowledge and become familiar with problem-solving approaches. Both books are classified under exam preparation, indicating that they are oriented toward course study and exam support, with an emphasis on practicality and usability. Since no clear records of the author's biography, education, or professional positions are available, no speculation is made here. In terms of subject matter alone, Liu Dingxiang's editorial work is characterized by a learner-oriented approach that stresses practice and mastery, making it suitable reference material for introductory and review stages of statistics study.
