4. Integration of Technology and Statistical Software | 技术与统计软件的整合
A major trend in the 2026 exam is the integration of technology. While the exam remains paper-based for the written component, the specification strongly encourages the use of statistical software during coursework or non-examined assessment, if applicable. Understanding software outputs (such as those from Excel, R, or Python) is now part of the exam questions.
2026年考试的一大趋势是技术的整合。尽管书面考试仍为纸笔形式，但考纲强烈鼓励在课程作业或非考试评估（如适用）中使用统计软件。理解软件输出（如Excel、R或Python的结果）如今已成为考试问题的一部分。
Sample assessment materials include questions where students are given a screenshot of a regression analysis table and must interpret coefficients, p-values, and R² values. This reflects the workplace demand for data interpretation skills.
样题中包含给出回归分析表格截图的问题，要求学生解释系数、p值和R²值。这反映了职场对数据解释技能的需求。
However, students will not be required to write code; they only need to read and interpret output. Teachers are advised to integrate spreadsheet exercises into lessons to build familiarity.
不过，学生不必编写代码；只需阅读并解释输出结果。建议教师在课堂上融入电子表格练习，以培养学生的熟练度。
5. Emphasis on Real-World Data Analysis | 对实际数据分析的重视
The 2026 specification moves away from contrived datasets towards authentic data sourced from government databases, scientific studies, and business reports. Students must learn to handle messy data, identify outliers, and decide on appropriate transformations.
2026版考纲摒弃了人为编造的数据集，转而采用来自政府数据库、科学研究和商业报告的真实数据。学生必须学会处理杂乱数据、识别异常值并决定合适的变换方法。
Contextual understanding is key: a question might provide COVID-19 case rates and ask students to compare mortality indices across regions, using standardisation techniques. This tests both statistical knowledge and global awareness.
情境理解至关重要：题目可能提供新冠病例率，要求学生运用标准化技术比较不同地区的死亡指数。这既考查统计知识，也考查全球意识。
