Mathematical Statistics is a fundamental and widely applied discipline that focuses on scientific methods for analyzing and processing random samples. It covers topics such as how to effectively collect data, estimate parameters, conduct hypothesis testing, study relationships among variables, and make statistical decisions. As one of the core foundational courses in statistics, its primary goal is to help students master the basic concepts and fundamental ideas of the discipline, develop the ability to apply common statistical methods in conjunction with prior knowledge from mathematics and probability theory to solve practical problems, gain an initial understanding of recent developments in mathematical statistics, and further cultivate statistical thinking.
