本研究选取人教版和Pearson版的高中数学教材，对于概率统计专题，研究了两版教材在结构安排、内容广度、内容深度、题目难度等方面的差异。研究发现，Pearson版统计部分的章节和篇幅更多；人教版概率与统计的章节安排更集中；Pearson版涵盖的知识面更广；人教版的知识更深，例题和习题也更难。

This study selected the high school mathematics textbooks of the People's Education Press and Pearson Education Press, comparing the differences between the two versions of textbooks in terms of structural arrangement, content breadth, content depth, and difficulty of problems, focusing on the topic of probability and statistics. This study found that the Pearson version had more chapters and content in the statistics section, while the People's Education Press version had a more concentrated arrangement of chapters on probability and statistics. The Pearson version covered a wider range of knowledge, while the People's Education Press version had deeper knowledge and more difficult example problems and exercises.
