1. Establish a good mathematical foundation: Mathematical statistics is a subject based on mathematics, so beginners need to master basic mathematical concepts such as algebra, geometry and calculus.

2. Learn the basic concepts of statistics: understand the basic concepts of statistics, such as population, sample, parameters and variables. , as well as common statistical indicators and distribution.

3. Learn to use statistical software: master one or more statistical software, such as Excel, SPSS, R, etc. , which can help you analyze and visualize data.

4. Read related textbooks and reference books: Choose a statistics textbook suitable for beginners and systematically learn the theory and methods of statistics. At the same time, we can refer to some classic statistical works to deepen our understanding of statistics.

5. Practical application: apply the learned statistical knowledge by solving practical problems, such as analyzing survey data and researching experimental results. This can help you better understand and master the application methods of statistics.

6. Attend relevant courses or training courses: Attend statistics-related courses or training courses to systematically learn and master statistical knowledge and methods, and communicate and discuss with other learners.

7. Do more exercises and problem sets: By doing a lot of exercises and problem sets, you can consolidate your statistical knowledge and improve your problem-solving ability and application ability.

In short, beginners need to establish a good mathematical foundation, learn the basic concepts and theories of statistics, master the use of statistical software, read relevant textbooks and reference books, practice and apply statistical knowledge, participate in relevant courses or training, and do more exercises and problem sets. Beginners can gradually improve their mathematical statistics ability through continuous study and practice.
