Abstract
The defining feature of the big data era is not simply "massive data volume," but a fundamental shift in data dimensions: high volume, variety, velocity, and low value density. Against this background, the foundational value of probability theory and mathematical statistics has become increasingly prominent-the former provides a rigorous mathematical framework for uncertainty, while the latter offers systematic methods for extracting regularities from data. Based on the knowledge foundation of high school students, this paper systematically reviews the core concepts of probability theory and mathematical statistics and their deep connections with big data, analyzes their foundational value in fields such as prediction, decision-making, algorithms, quality control, and causal analysis, and illustrates them through three real-life cases: recommendation systems, epidemic forecasting, and learning analytics. The study shows that the relationship among the three can be aptly compared to "a building, its foundation, and its superstructure": probability theory is the theoretical foundation, mathematical statistics is the methodological bridge, and big data is the frontier of application. On this basis, the paper further discusses the implications for high school mathematics education: dispelling the myth that "mathematics is useless," cultivating statistical thinking and data awareness, and laying the groundwork for data literacy in the age of intelligence.
