📚 Year 8 SQA Statistics: Progression Bridging Guide | Year 8 SQA 统计：升学衔接指南

Welcome to the Year 8 SQA Statistics Bridging Guide. Whether you are preparing for the transition from the Broad General Education to the Senior Phase or building a solid foundation for National 5 Applications of Mathematics, this guide will help you connect the dots between primary data handling and the statistical reasoning required for the SQA qualifications. By understanding key concepts now, you will be better equipped to tackle more advanced topics such as sampling, probability distributions, and hypothesis testing in later years.

欢迎阅读Year 8 SQA 统计衔接指南。无论你是在为从广泛通识教育向高阶阶段过渡做准备，还是希望为 National 5 应用数学打下坚实基础，本指南都将帮助你串联起基础数据处理与 SQA 资格所要求的统计推理。现在掌握了关键概念，将来就能更从容地应对抽样、概率分布和假设检验等更高阶的主题。

1. The SQA Statistics Framework | SQA 统计框架

In Scotland, statistics is embedded within the Mathematics curriculum from early years. Year 8 (typically S2) is part of the Broad General Education (BGE), where you explore data handling, chance, and uncertainty. The experiences and outcomes are designed to develop your statistical literacy so that you can move seamlessly into the Senior Phase, where National 4, National 5, and Higher courses demand a more formal approach to statistics.

在苏格兰，统计从早期开始就融入数学课程。Year 8（通常为 S2）属于广泛通识教育（BGE）阶段，你会在其中探索数据处理、机遇与不确定性。相关的体验与成果旨在培养你的统计素养，让你能够平稳过渡到高阶阶段，那时 National 4、National 5 和 Higher 课程会对统计方法提出更正式的要求。

By the end of S2, you should be able to interpret statistical information, choose appropriate graphs, calculate averages, and understand simple probability. These are all building blocks for the statistical content in National 5, such as comparing data sets using mean and standard deviation, or using probability to assess risk.

在 S2 结束时，你应该能够解读统计信息、选择合适的图表、计算平均数并理解简单概率。这些都是 National 5 中统计内容的基石，例如用均值与标准差比较数据集，或用概率评估风险。

2. Types of Data: Qualitative and Quantitative | 数据类型：定性与定量

All statistical analysis starts with understanding what type of data you are dealing with. Data can be qualitative (categorical) or quantitative (numerical). Qualitative data describes qualities, like eye colour or favourite subject. Quantitative data is numerical and can be discrete or continuous. Discrete data can only take certain values, for example, number of students in a class. Continuous data can take any value within a range, such as height or time.

一切统计分析都从理解你处理的是何种类型的数据开始。数据可以是定性的（分类）或定量的（数值）。定性数据描述特征，如眼睛颜色或最喜欢的科目。定量数据是数值型的，可以是离散的或连续的。离散数据只能取某些特定的值，例如班级里的学生人数。连续数据则可以在某个范围内取任意值，如身高或时间。
