"Statistics and Probability" is compiled in coordination with the implementation of "Mathematics Curriculum Standard for Ordinary Senior High Schools (Experiment)". The key point is to provide teachers with mathematics teaching resources that match the concepts and methods of the curriculum standard, and then provide teachers with supplementary resources of professional knowledge and methods. The purpose is to help teachers master the relevant contents of the curriculum standard and better understand and handle the teaching of the new curriculum.

Statistics and Probability can not only be used as a reference book for teachers' training and daily teaching in implementing the new mathematics curriculum in senior high schools, but also become a reference book for teachers to develop their own teaching resources and improve the professional level of mathematics.
