Research and Application of Probability and Statistics in Practical Teaching

: With the progress of today's society, the policies in the field of education have also been improved, including mathematics education. As the content of probability and statistics has increased significantly in mathematics textbooks, the teaching syllabus has also been constantly adjusted to adapt to the current mathematics teaching reform, and the teaching methods have also been constantly changing. Although the teaching content of probability and statistics has been gradually expanded and distributed in today's mathematics teaching, there is still a lot of room for improvement in terms of textbook content, teachers' teaching and students' learning. This paper expounds the mathematical thinking and characteristics in statistics and probability, roughly summarizes the problems and obstacles in mathematics teaching, and puts forward the teaching principles and strategies that should be paid attention to in mathematics teaching, in order to cultivate students' mathematical thinking through the teaching of probability and statistics, excavate the deeper connotation and significance contained in probability and statistics, and provide practical value for the research and application of mathematics teaching.
