Situation, as one of the four aspects that reflect the core literacy of mathematics, is also the carrier of the study quality level and core literacy. At the same time, probability and statistics is one of the main lines of high school mathematics curriculum content. This paper takes the "probability and statistics" questions in seven sets of 2023 National Mathematics paper A (Science), National Mathematics paper B (Science), new college entrance examination paper I, new college entrance Examination paper II as the research object, and analyzes them from the type of situation and the level of investigation. It is found that the realistic situation is relatively large and the level is rich, the mathematical situation is relatively small and the examination level is single, and the comprehensive level situation is often presented with the solution problem and the proportion is large. Finally, some teaching suggestions are put forward for teachers: teachers should renew the discipline concept and promote the cross-integration of various disciplines; Teach students "mathematical reading", improve the ability to extract effective information quickly; Focus on revealing the essence of probability and statistics knowledge, and guide students to understand the ideas and methods contained in it.
