1. Course Structure and Assessment Overview | 课程结构与评估概览
The Edexcel GCSE Statistics specification (1ST0) is designed to develop your ability to collect, analyse, and interpret data. In Year 10, you build the foundational skills needed for the final linear examinations taken at the end of Year 11. The course is assessed through two equally weighted written papers, each 1 hour 30 minutes long, covering both Foundation and Higher tiers. The papers test your knowledge of statistical methods, probability, and data handling, with questions ranging from short calculations to extended problem‑solving tasks.
爱德思 GCSE 统计学规范（1ST0）旨在培养你收集、分析和解读数据的能力。在 Year 10，你将打下基础技能，为 Year 11 结束时参加的最终线性考试做好准备。该课程通过两份权重相同的笔试进行评估，每份试卷时长 1 小时 30 分钟，覆盖基础级别和高级别。试卷考查你的统计方法、概率和数据处理知识，题型从简短计算到拓展性问题解决任务均有涉及。
2. Planning and Data Collection | 数据收集规划
Every statistical investigation begins with a clear plan. You will learn to formulate a hypothesis, identify the population of interest, and design a sampling strategy. Key sampling methods include simple random sampling, stratified sampling, systematic sampling, and quota sampling. Understanding the strengths and weaknesses of each method is essential, as the choice of sampling directly affects the validity and reliability of your conclusions. You will also consider primary and secondary data sources, and how to avoid bias in questionnaires and surveys.
每项统计调查都始于清晰的规划。你将学习如何提出假设、确定目标总体以及设计抽样策略。关键的抽样方法包括简单随机抽样、分层抽样、系统抽样和配额抽样。理解每种方法的优缺点至关重要，因为抽样的选择直接影响结论的有效性和可靠性。你还会考虑一手和二手数据来源，以及如何避免问卷和调查中的偏差。
3. Types of Data and Data Classification | 数据类型与数据分类
Data comes in many forms, and classifying it correctly is the first step in choosing the right analysis. You will distinguish between qualitative and quantitative data, and further split quantitative data into discrete and continuous. In addition, you will work with categorical, ordinal, and numerical scales. Understanding these distinctions helps you select appropriate diagrams, summary statistics, and inferential methods later in the course.
数据有多种形式，正确分类是选择正确分析方法的第一步。你将区分定性数据和定量数据，并进一步将定量数据分为离散型和连续型。此外，你还会接触分类尺度、定序尺度和数值尺度。理解这些区别有助于你在后续课程中选用恰当的图表、汇总统计量和推断方法。
4. Tabulation and Graphical Representation | 表格与图形表示
Effective data presentation is a core skill. You will learn to construct and interpret frequency tables, two‑way tables, and tally charts. For graphical representation, you will master bar charts, pie charts, pictograms, stem‑and‑leaf diagrams, and population pyramids. Each type of diagram has specific rules about labelling, scaling, and interpretation, and you will be expected to choose the most suitable format for a given dataset.
有效的数据展示是一项核心技能。你将学习构建和解读频数表、双向表和计数表。在图形表示方面，你将掌握条形图、饼图、象形图、茎叶图和人口金字塔。每种图都有关于标签、比例和解读的特定规则，你需要为给定数据集选择最合适的展示形式。
5. Measures of Central Tendency | 集中趋势的度量
Summarising the centre of a dataset is fundamental. You will calculate and interpret the mean, median, and mode for both raw data and grouped frequency tables. Special attention is given to finding the modal class and estimating the mean from grouped data using midpoints. You will also learn when each measure is most appropriate, such as using the median when outliers are present, or the mode for categorical data.
概括数据集的中心是基础。你将计算和解读原始数据和分组频数表的平均数、中位数和众数。重点包括找到众数所在组以及利用组中值估算分组数据的平均数。你还将学习每种度量在何种情况下最适用，例如存在异常值时使用中位数，或对分类数据使用众数。
6. Measures of Spread and Dispersion | 离散程度的度量
Alongside the centre, you need to understand how spread out the data are. You will work with the range, interquartile range (IQR), and percentiles. The IQR, found by subtracting the lower quartile (Q₁) from the upper quartile (Q₃), is a robust measure that is not affected by extreme values. You will also construct and interpret box plots (box‑and‑whisker diagrams) to visually compare distributions and identify outliers. The concept of standard deviation is introduced at Higher tier, along with its formula.
除了中心，你还需要理解数据的离散程度。你将学习极差、四分位距（IQR）和百分位数。四分位距通过上四分位数（Q₃）减去下四分位数（Q₁）得到，是一种不受极端值影响的稳健度量。你还将构建并解读箱线图（箱须图），以直观比较分布并识别异常值。在高级别中会引入标准差的概念及其公式。
7. Scatter Graphs and Correlation | 散点图与相关性
Relationships between two variables are explored through scatter graphs. You will plot bivariate data and describe the correlation as positive, negative, or zero, and further assess its strength (strong, moderate, weak). The line of best fit (regression line) is drawn by eye, and you will use it to make predictions via interpolation. Higher tier students will also learn to interpret the equation of the line of best fit and understand the concept of causation versus association.
两个变量之间的关系通过散点图探讨。你将绘制双变量数据并描述相关性为正、负或无相关，并进一步评估其强度（强、中、弱）。最佳拟合线（回归线）通过目测绘制，你将用它通过内插法进行预测。高级别的学生还将学习解读最佳拟合线的方程，并理解因果关系与关联关系的概念。
8. Time Series and Moving Averages | 时间序列与移动平均
Data collected over time requires special techniques. You will plot time series graphs and identify trends and seasonal variations. The method of moving averages is used to smooth out short‑term fluctuations and reveal the underlying trend. You will calculate a moving average and use it, together with average seasonal effects, to make rough forecasts. This topic bridges statistics with real‑world applications like economic data and sales forecasts.
随时间收集的数据需要特殊技术。你将绘制时间序列图并识别趋势和季节性波动。移动平均法用于消除短期波动并揭示根本趋势。你将计算移动平均数，并结合平均季节效应进行粗略预测。该主题将统计学与经济学数据和销售预测等现实应用联系起来。
9. Index Numbers | 指数
Index numbers are used to compare changes in price, quantity, or value over time relative to a base year. You will learn to calculate simple index numbers and weighted index numbers, such as the Retail Price Index (RPI). Understanding how to interpret these figures is crucial for topics like inflation and economic performance. You will also chain multiple indices together to compare different time periods.
指数用于比较价格、数量或价值相对于基年随时间的变化。你将学习计算简单指数和加权指数，例如零售价格指数（RPI）。理解如何解读这些数据对于通货膨胀和经济表现等课题至关重要。你还将多个指数链接在一起以比较不同时间段。
10. Probability Fundamentals | 概率基础
A solid grasp of probability is essential for statistical inference. You will study the probability scale from 0 to 1, experimental and theoretical probability, and the concepts of mutually exclusive and independent events. Using Venn diagrams and tree diagrams, you will calculate combined probabilities, including conditional probability at Higher tier. The addition law and multiplication law are applied to solve complex problems.
扎实掌握概率知识对统计推断至关重要。你将学习从 0 到 1 的概率尺度、实验概率和理论概率，以及互斥事件和独立事件的概念。利用文氏图和树形图，你将计算组合概率，高级别还包括条件概率。加法法则和乘法法则用于解决复杂问题。
11. Probability Distributions and Binomial Distribution | 概率分布与二项分布
The probability distribution of a discrete random variable lists all possible outcomes and their probabilities. You will construct and use these tables to find expected values. At Higher tier, the binomial distribution B(n, p) is introduced as a model for a fixed number of independent trials with two possible outcomes. You will calculate probabilities using the formula P(X = r) = ⁿCᵣ pʳ (1-p)ⁿ⁻ʳ and apply it to real‑life contexts such as quality control.
离散随机变量的概率分布列出了所有可能的结果及其概率。你将构建并使用这些表格求期望值。在高级别，二项分布 B(n, p) 被引入，作为固定次数独立试验且只有两种可能结果的模型。你将使用公式 P(X = r) = ⁿCᵣ pʳ (1-p)ⁿ⁻ʳ 计算概率，并将其应用于质量检验等实际场景。
12. Revision Strategies and Key Skills | 复习策略与关键技能
Success in Edexcel Statistics requires consistent practice and a clear understanding of command words like “estimate”, “compare”, and “interpret”. Regularly work through past paper questions, paying special attention to the later parts of each question that require written explanation. Build your statistical vocabulary and always check your working, especially when reading values from graphs or tables. The ability to communicate findings clearly in plain English is as important as the numerical calculations themselves.
在爱德思统计学中取得成功需要持续练习，并清楚理解“估算”、“比较”和“解读”等指令词。定期练习历年真题，特别注意每道题后半部分需要书面解释的部分。积累你的统计词汇，并始终检查演算过程，尤其是在从图表或表格读取数值时。用清晰的普通英语传达发现的能力与数值计算本身同样重要。
