Welcome to your summer preparation guide for Year 8 CCEA Statistics. Whether you are excited about diving into data or feeling a little unsure about what lies ahead, this bridging course will help you build confidence before the new school year begins. We will walk through the key topics you will encounter, suggest simple revision activities, and show you how statistics connects to the real world.

欢迎来到 Year 8 CCEA 统计的暑期预习指南。无论你对探索数据感到兴奋，还是对即将学习的内容有些不确定，这个衔接课程都能帮助你在新学年开始前建立信心。我们将带你浏览 Year 8 涉及的主要课题，给出简单的复习活动建议，并展示统计学如何与现实世界紧密相连。

1. Welcome to Year 8 Statistics | 欢迎学习 Year 8 统计

Year 8 statistics in the CCEA curriculum builds on what you learned in primary and Year 7. You will move from simple graphs to more detailed data analysis, and you will start to think critically about how data is collected and presented.

在 CCEA 课程中，Year 8 统计建立在小学和 Year 7 所学的基础上。你将从不简单的图表走向更详细的数据分析，并开始批判性地思考数据是如何收集和呈现的。

This year, you will be expected to design your own small surveys, choose appropriate charts, and explain what averages and spread reveal about a dataset. It is more than just drawing graphs — it is about telling the story behind the numbers.

这一年，你需要设计自己的小调查，选择合适的图表，并解释平均数和离散程度揭示了数据集的哪些信息。统计不仅仅是画图——关键在于讲述数字背后的故事。

2. Why Study Statistics? | 为什么学习统计？

Statistics is about collecting, organising, analysing and interpreting data. We use it to answer questions, spot trends and make informed decisions. From medical research to the scores on your favourite video game, statistics helps us understand what the information really means.

统计是关于收集、整理、分析和解读数据。我们用它来回答问题、发现趋势并做出明智的决定。从医学研究到你最喜欢的电子游戏得分，统计帮助我们理解信息的真正含义。

Developing a statistical mindset will also sharpen your critical thinking skills. You will learn to ask, ‘Is this graph misleading?’, ‘Was the sample large enough?’ and ‘What does the average actually hide?’

培养统计思维还能提高你的批判性思维能力。你将学会问：“这个图表有误导性吗？” “样本量足够大吗？” 以及 “平均值实际隐藏了什么信息？”

3. Bridging from Year 7: What to Recap | 衔接 Year 7 知识回顾

Before you move on, it is helpful to review the statistics you already know. In Year 7, you likely worked with frequency tables, tally charts, bar charts and pictograms. Make sure you can read data from these representations with ease.

在继续学习之前，复习已经掌握的统计知识很有帮助。Year 7 时你可能接触过频数表、计数表、条形图和象形图。确保你能轻松地从这些呈现方式中读取数据。

You should also feel comfortable with the terms ‘mean’, ‘mode’ and ‘range’, even if only at an introductory level. Understanding what each one tells you about a small set of numbers is a key stepping stone.

你还应该对“平均数”、“众数”和“极差”这些术语感到不陌生，哪怕只是入门水平。理解它们各自揭示了关于一小群数字的什么信息，是重要的进阶基石。

Have a go at this quick check: if a group of students scored 4, 6, 7, 7 and 9 on a quiz, can you find the mode? (It is 7.) Can you find the range? (9 – 4 = 5.)

来做个快速自测：如果一组学生在测验中得了 4、6、7、7 和 9 分，你能找到众数吗？（是 7。）你能找到极差吗？（9 – 4 = 5。）

4. Understanding Data Types | 理解数据类型

In Year 8, you will learn to classify data into two main types: categorical (qualitative) and numerical (quantitative). Categorical data describes qualities, like favourite
