The syllabus is assessed entirely through two written examination papers, with no coursework component. This structure places a premium on mastering both theoretical knowledge and practical problem-solving skills. Throughout Year 10, you will cover roughly half of the content, laying the groundwork for the more advanced topics in Year 11.
该课程大纲完全通过两份书面考试进行评估，不包含课程作业部分。这种结构使得掌握理论知识和实际解题能力变得尤为重要。在整个 Year 10 期间，你将学习大约一半的内容，为 Year 11 更高级的主题奠定基础。
2. Course Aims and Objectives | 课程目标与宗旨
The syllabus aims to foster an understanding of the basic principles of statistics and how they apply to everyday situations. It encourages students to develop a logical approach to problem-solving, to interpret statistical reports, and to communicate findings clearly. By the end of Year 10, you should be able to describe patterns in data, calculate summary statistics, and evaluate the reliability of conclusions.
该课程大纲旨在培养学生对统计学基本原理的理解，以及如何将其应用于日常情境。它鼓励学生形成逻辑性的解题思路，解释统计报告，并清晰地交流发现。在 Year 10 结束时，你应该能够描述数据模式、计算汇总统计量，并评估结论的可靠性。
Key objectives for the first year include becoming familiar with different types of data, understanding sampling techniques, constructing various charts and diagrams, and performing calculations for measures of central tendency and dispersion. These skills are not only examinable but also invaluable for subjects like geography, biology, and economics.
第一年的关键目标包括熟悉不同类型的数据、理解抽样技术、构建各种图表，以及进行集中趋势和离中趋势指标的计算。这些技能不仅具有考试价值，在地理、生物和经济学等学科中也极为宝贵。
3. Overview of the Syllabus Content | 课程大纲内容概览
The CIE IGCSE Statistics syllabus is organised into distinct sections that progressively build statistical competence. The core topics include: data collection and sampling, descriptive statistics, probability, graphical representation, correlation and regression, and index numbers. In Year 10, the focus typically rests on the first four areas, with an introduction to bivariate data later in the year.
CIE IGCSE 统计课程大纲分为不同模块，逐步构建统计能力。核心主题包括：数据收集与抽样、描述统计、概率、图形表示、相关与回归，以及指数。在 Year 10，重点通常放在前四个领域，并在学年后期引入双变量数据。
Understanding the weight of each topic helps you allocate revision time effectively. For example, descriptive statistics and data representation together account for a significant portion of the examination. The table below summarises the approximate topic weighting across the syllabus.
了解每个主题的权重有助于你有效分配复习时间。例如，描述统计和数据表示合在一起在考试中占有很大比重。下表概括了各主题在课程大纲中的大致权重。
| Topic | 主题 | Approximate Weighting | 大致权重 |
|---|---|
| Data Collection and Sampling | 10-15% |
| Descriptive Statistics | 25-30% |
| Graphical Representation | 20-25% |
| Probability | 15-20% |
| Correlation and Regression | 10-15% |
| Index Numbers and Other Topics | 5-10% |
4. Data Collection and Sampling | 数据收集与抽样
This section introduces the fundamentals of gathering data. You will learn to distinguish between primary and secondary data, and between quantitative (discrete and continuous) and qualitative data. Year 10 students must also understand the difference between a population and a sample, and why sampling is necessary in statistical investigations.
本部分介绍数据收集的基础知识。你将学习区分一手数据和二手数据，以及定量数据（离散和连续）与定性数据。Year 10 学生还必须理解总体与样本之间的区别，以及为何在统计调查中需要进行抽样。
Sampling methods form a key part of the syllabus. You need to know the advantages and disadvantages of random, stratified, systematic, and quota sampling. For example, stratified sampling ensures subgroups are proportionally represented, while systematic sampling involves selecting every kth item from a list. These concepts are often tested through scenario-based questions.
抽样方法是课程大纲的关键组成部分。你需要了解随机抽样、分层抽样、系统抽样和配额抽样的优缺点。例如，分层抽样能确保子群体按比例被代表，而系统抽样则涉及从列表中每隔 k 个项目进行选择。这些概念常通过情景题进行测试。
Designing a questionnaire or survey is another practical skill covered. You should be able to critique questions for bias, ambiguity, or leading wording, and suggest improvements. A well-designed data collection sheet ensures that the information gathered is accurate and easy to process.
设计问卷或调查是另一项需要掌握的实践技能。你应当能够就偏向性、模糊性或诱导性措辞对问题进行评析，并提出改进建议。设计良好的数据收集表能确保所收集的信息准确且易于处理。
5. Descriptive Statistics: Measures of Central Tendency | 描述统计：集中趋势指标
Measures of central tendency are among the first calculations Year 10 students master. The mean, median, and mode each provide a different way to summarise a data set with a single value. The mean is calculated as the sum of all observations divided by the number of observations, and is highly sensitive to extreme values.
集中趋势指标是 Year 10 学生最先掌握的计算之一。均值、中位数和众数各自提供了用单一数值概括数据集的不同方式。均值计算为所有观察值的总和除以观察值的个数，并对异常值高度敏感。
The median is the middle value when data are ordered; for an even number of observations, it is the average of the two central values. The median is often preferred when data are skewed, as it is not affected by outliers. The mode is the most frequently occurring value and is particularly useful for categorical data.
中位数是将数据排序后位于中间的值；当观察值个数为偶数时，它是中间两个值的平均数。在数据偏斜时，中位数往往更受青睐，因为它不受异常值影响。众数是出现频率最高的值，对于分类数据尤为有用。
For grouped data, you will learn to estimate the mean using midpoints of class intervals and to identify the modal class. The formula for the estimated mean of grouped data is commonly written as:
对于分组数据，你将学会利用组中值来估算均值，并确定众数组。分组数据估算均值的公式通常写作：
x̄ = Σfx / Σf
where f is the frequency of each class and x is the class midpoint. Understanding how to apply this formula correctly is essential for exam success.
其中 f 为每个组的频数，x 为组中值。正确理解如何应用此公式对于考试成功至关重要。
6. Descriptive Statistics: Measures of Spread | 描述统计：离散程度指标
While measures of central tendency describe the centre of a data set, measures of spread describe how data are dispersed. The range, interquartile range (IQR), variance, and standard deviation are all covered in the syllabus. In Year 10, you will focus on the range, quartiles, and IQR before moving on to more complex measures.
集中趋势指标描述数据集的中心，而离散程度指标则描述数据的分散情况。课程大纲涵盖了极差、四分位距（IQR）、方差和标准差。在 Year 10，你将重点学习极差、四分位数和 IQR，之后再过渡到更复杂的指标。
The range is simply the difference between the maximum and minimum values. The lower quartile (Q₁) and upper quartile (Q₃) are found by splitting the ordered data into four equal parts. The IQR, defined as Q₃ - Q₁, measures the spread of the middle 50% of the data and is resistant to outliers.
极差就是最大值与最小值之差。下四分位数（Q₁）和上四分位数（Q₃）通过将排序后的数据等分为四部分得到。IQR 定义为 Q₃ - Q₁，衡量中间 50% 数据的离散程度，且不受异常值影响。
Later in the course, you will encounter variance and standard deviation, which give a more precise measure of dispersion around the mean. The population standard deviation formula is:
在课程后期，你将接触到方差和标准差，它们能更精确地衡量围绕均值的离散程度。总体标准差公式为：
σ = √[ Σ(x - μ)² / N ]
For a sample, the denominator changes to n - 1. Year 10 students should begin to grasp the conceptual difference between these two versions.
对于样本，分母变为 n - 1。Year 10 学生应开始理解这两个版本之间的概念差异。
7. Representing Data Graphically | 数据的图形表示
Graphical representation is a major component of the syllabus, requiring students to construct, interpret, and compare a wide range of diagrams. In Year 10, you will work with bar charts, pie charts, histograms, frequency polygons, stem-and-leaf diagrams, and box-and-whisker plots. Each type of diagram is suited to specific data types and purposes.
图形表示是课程大纲的主要组成部分，要求学生构建、解释并比较多种图表。在 Year 10，你将学习条形图、饼图、直方图、频数多边形、茎叶图和箱线图。每种图表类型都适用于特定的数据类型和目的。
Histograms are particularly important for continuous data grouped into class intervals. Unlike bar charts, the area of each bar in a histogram is proportional to the frequency. When class widths are unequal, you must use frequency density, calculated as frequency divided by class width. A common mistake is to plot frequency instead of frequency density.
直方图对于分成组区间的连续数据尤为重要。与条形图不同，直方图中各条形的面积与频数成正比。当组距不相等时，你必须使用频数密度，其计算为频数除以组距。常见的错误是绘制频数而非频数密度。
be able to draw a box plot from a five-number summary and identify outliers using the rule: any value less than Q₁ - 1.5 × IQR or greater than Q₃ + 1.5 × IQR is considered an outlier.
箱线图能直观地概括中位数、四分位数和极值。它们在比较分布时非常出色。你必须能够根据五数概括法绘制箱线图，并利用规则识别异常值：任何小于 Q₁ - 1.5 × IQR 或大于 Q₃ + 1.5 × IQR 的值都被视为异常值。
8. Introduction to Probability | 概率入门
Probability is the study of uncertainty and random events. The Year 10 syllabus introduces the probability scale from 0 to 1, and the terms impossible, unlikely, even chance, likely, and certain. You will learn to calculate theoretical probability as the number of favourable outcomes divided by the total number of possible outcomes, assuming all outcomes are equally likely.
概率是研究不确定性和随机事件的学科。Year 10 课程大纲引入了从 0 到 1 的概率标度，以及不可能、不太可能、等可能、很可能和确定等术语。你将学会计算理论概率，即有利结果的数量除以所有可能结果的总数，基于所有结果等可能发生的假设。
Venn diagrams and tree diagrams are essential tools for solving probability problems. You will use Venn diagrams to represent sets and their unions, intersections, and complements. The notation A ∪ B (A union B) and A ∩ B (A intersect B) should become second nature. Tree diagrams help break down multistage events, with probabilities multiplied along branches and added for combined outcomes.
韦恩图和树状图是解决概率问题的重要工具。你将使用韦恩图来表示集合及其并集、交集和补集。符号 A ∪ B（A 并 B）和 A ∩ B（A 交 B）应成为你的第二天性。树状图有助于分解多阶段事件，沿分支相乘概率，并将组合结果相加。
Conditional probability is also introduced at a basic level. For example, the probability that event B occurs given that event A has already occurred is written as P(B|A). Year 10 students should practise applying the formula:
条件概率也在基础层面被引入。例如，在事件 A 已经发生的情况下事件 B 发生的概率记为 P(B|A)。Year 10 学生应练习应用以下公式：
P(B|A) = P(A ∩ B) / P(A)
Understanding this concept is crucial for tackling more complex probability questions in Year 11.
理解这一概念对于应对 Year 11 更复杂的概率问题至关重要。
9. The Statistical Enquiry Cycle | 统计探究周期
The syllabus emphasises the statistical enquiry cycle as a framework for conducting investigations. The cycle consists of five stages: identifying a problem or question, planning the data collection, collecting the data, processing and presenting the data, and drawing conclusions. Year 10 students are encouraged to apply this cycle to small projects.
课程大纲强调将统计探究周期作为进行调查的框架。该周期包括五个阶段：确定问题或提问、规划数据收集、收集数据、处理和呈现数据，以及得出结论。鼓励 Year 10 学生将此周期应用于小型项目。
In the problem phase, you learn to formulate clear, measurable hypotheses. During planning, you decide on sampling strategies and data collection instruments. The processing stage involves calculations and graph construction, and the conclusion stage requires you to relate findings back to the original question, noting any limitations or possible improvements.
在问题阶段，你学习提出清晰、可测量的假设。在规划阶段，你决定抽样策略和数据收集工具。处理阶段涉及计算和图表构建，而结论阶段则需要你将发现与原始问题联系起来，并指出任何局限性或可能的改进。
Mastering this cycle not only prepares you for exam questions that ask you to design a statistical investigation but also builds transferable skills for research in higher education.
掌握这一周期不仅能让你为要求设计统计调查的考试题目做好准备，还能为高等教育的研究培养可迁移技能。
10. Assessment Overview and Exam Papers | 评估概览与考试试卷
The CIE IGCSE Statistics assessment consists of two compulsory papers, both taken at the end of the course in Year 11. Paper 1 (Core) and Paper 2 (Extended) cater to different grade thresholds, but most students are entered for the Extended tier to access grades up to A*. It is important to check with your school which tier you will be following.
CIE IGCSE 统计学的评估由两份必考试卷组成，均在 Year 11 课程结束时进行。试卷一（核心）和试卷二（扩展）对应不同的等级门槛，但大多数学生参加扩展级别考试，以获得最高 A* 的成绩。务必与学校确认你将参加哪个级别的考试。
| Paper | 试卷 | Duration | 时长 | Marks | 满分 | Weighting | 权重 |
|---|---|---|---|
| Paper 1 (Short-answer questions) | 1 hour 30 min | 80 | 50% |
| Paper 2 (Structured and longer questions) | 2 hours | 100 | 50% |
Both papers allow the use of a scientific calculator. Paper 2 often includes questions that require you to interpret output from software or to comment on the validity of statistical arguments. Starting early preparation in Year 10 by working through past papers will give you a significant advantage.
两份试卷均允许使用科学计算器。试卷二通常包含要求你解释软件输出或评论统计论证有效性的题目。在 Year 10 就开始通过历年真题进行准备，将为你带来显著优势。
11. Tips for Effective Year 10 Preparation | Year 10 高效备考建议
Thriving in Year 10 Statistics requires a blend of consistent practice, conceptual clarity, and active revision. Start by creating a vocabulary list of key statistical terms and their definitions, such as 'bivariate data', 'explanatory variable', 'response variable', and 'index number'. This discipline prevents confusion when you encounter these terms in exam questions.
要在 Year 10 统计学中脱颖而出，需要持续练习、概念清晰和主动复习三者结合。首先，制作一份关键统计术语及其定义的词汇表，例如“双变量数据”、“解释变量”、“响应变量”和“指数”。这种训练能防止你在考试题目中遇到这些术语时感到困惑。
Make full use of graphical tools. Practise drawing histograms, cumulative frequency curves, and scatter diagrams neatly and accurately, as presentation marks are often awarded. Work on interpreting graphs, not just constructing them: examiners will ask you to compare distributions, spot trends, and describe correlations in context.
充分利用图形工具。练习整洁、准确地绘制直方图、累积频数曲线和散点图，因为呈现分往往会被计入。要练习解读图形，而不仅仅是构建图形：考官会要求你比较分布、发现趋势，并结合情境描述相关性。
Finally, engage with real-world data. Analyse statistics from news articles, sports results, or scientific studies. This habit deepens your appreciation of the subject and trains you to think critically about sources of bias, sampling errors, and the difference between correlation and causation. Remember, statistics is a practical discipline, not just a set of formulas.
最后，接触真实世界的数据。分析新闻报道、体育比赛结果或科学研究中的统计数据。这一习惯能加深你对学科的理解，并训练你批判性地思考偏误来源、抽样误差以及相关性与因果关系的区别。请记住，统计学是一门实践学科，而不仅仅是一套公式。
