📚 S1 OCR Papers: Downloadable Past Papers and Mark Schemes | OCR S1 历年真题与评分方案下载

Statistics 1 (S1) is the first statistics unit that OCR students meet at A Level, and it is also one of the most predictable papers in the whole mathematics suite. Because the question styles repeat so regularly, working through genuine OCR past papers is the single most efficient way to raise your mark. This page collects every downloadable S1 OCR question paper and mark scheme we host, together with a practical revision guide covering the syllabus, the exam format, grade boundaries, the formulas you must memorise and the mistakes examiners see year after year.

统计 1（S1）是 OCR 学生在 A Level 阶段接触的第一个统计单元，也是整个数学科目中最有规律可循的一张卷子。正因为它出题风格高度重复，刷真正的 OCR 历年真题就是提分效率最高的方法。本页汇总了我们托管的所有 OCR S1 试卷与评分方案下载链接，并附上一份实用备考指南，涵盖考纲范围、考试形式、分数线、必背公式，以及考官报告中反复出现的失分点。

1. What Are OCR S1 Papers? | 什么是 OCR S1 真题

OCR S1 refers to Statistics 1, the introductory statistics unit within the OCR GCE Mathematics specification. For most of the period covered by the papers on this page (January 2005 to June 2016) OCR Mathematics was a modular qualification, and S1 was one of the applied units students could choose alongside mechanics and decision mathematics. Each unit had its own short examination and its own bank of past papers, which is why the files below are labelled simply "S1 OCR".

OCR S1 指的是 Statistics 1，即 OCR GCE 数学考纲中的入门统计单元。在本页试卷所覆盖的大部分年份（2005 年 1 月至 2016 年 6 月）里，OCR 数学采用的是模块化考试，S1 是学生可以在力学、决策数学之外选择的应用单元之一。每个单元都有独立的短卷和独立的真题库，这正是下列文件简单标注为 "S1 OCR" 的原因。

A parallel unit exists under the OCR MEI specification, and a large part of the content overlaps. If your school enters you for OCR MEI Mathematics, the papers here are still excellent practice, but always check the MEI specification for topics such as the geometric distribution, which is examined differently across the two specifications.

OCR MEI 考纲下也有一个平行单元，内容有大量重叠。如果你所在学校为你报考的是 OCR MEI 数学，本页试卷依然是很好的练习材料，但涉及几何分布等考点时，请务必对照 MEI 考纲，因为两个考纲对同一知识点的考查方式并不完全相同。

2. What Topics Does OCR S1 Cover? | OCR S1 考查哪些知识点

OCR S1 is deliberately narrow. Almost every question you will ever see falls into one of five or six topic families, and each family has a small number of standard question types. Learning to recognise those types is more valuable than learning more theory.

OCR S1 的范围刻意收得很窄。你几乎不会遇到五大六类主题之外的题目，而每一类主题下的标准题型数量也很有限。学会辨认题型，比多学理论更有价值。

• Representation and summary of data: stem-and-leaf diagrams, box-and-whisker plots, histograms with equal and unequal class widths, cumulative frequency curves, mean, median, mode, quartiles, percentiles, interquartile range, standard deviation, outliers and skewness.
  数据的表示与概括：茎叶图、箱线图、等宽与不等宽分组直方图、累积频数曲线、平均数、中位数、众数、四分位数、百分位数、四分位距、标准差、离群值与偏态。
• Probability: equally likely outcomes, Venn diagrams, tree diagrams, the addition and multiplication laws, mutually exclusive and independent events, and conditional probability.
  概率：等可能结果、韦恩图、树状图、加法与乘法法则、互斥事件与独立事件、条件概率。
• Discrete random variables: probability distribution tables, expectation E(X), variance Var(X), and the effect of the transformation aX + b.
  离散型随机变量：概率分布表、期望 E(X)、方差 Var(X)，以及线性变换 aX + b 的影响。
• The binomial distribution: p) is appropriate, calculating probabilities, and using E(X) = np and Var(X) = np(1 − p).
  二项分布：判断何时适用 B(n, p)、计算概率，以及使用 E(X) = np 与 Var(X) = np(1 − p)。
• The normal distribution: standardising, reading tables or using the calculator, and inverse normal problems.
  正态分布：标准化、查表或使用计算器，以及反查正态分布的问题。
• The geometric distribution (specification dependent): P(X = r) = (1 − p)ʳ⁻¹ p and E(X) = 1 ÷ p.
  几何分布（视考纲而定）：P(X = r) = (1 − p)ʳ⁻¹ p 与 E(X) = 1 ÷ p。

Before you start a paper, write the topic list above onto a single sheet of paper. After each past paper, tick the topics that appeared and note the question numbers. Within three or four papers you will see clear patterns, and you will know exactly which topic needs more work.

在开始做卷子之前，先把上面的主题清单抄到一张纸上。每做完一套真题，就勾出出现过的主题并记下题号。做三四套之后，规律就非常明显了，你也能准确知道哪个主题还需要补。

3. January Session Papers | 一月场次真题下载

The January series ran from 2005 until 2013 for S1. Every file below is a PDF; the question paper (QP) contains the questions, and the mark scheme (MS) shows exactly how each mark is awarded. Download both, and never open the mark scheme before you have finished the paper under timed conditions.

S1 的一月场次从 2005 年一直考到 2013 年。以下每个文件都是 PDF：试卷（QP）是题目本身，评分方案（MS）则逐分说明每个得分点是如何给出的。两个都下载，但在限时完成试卷之前，绝不要先打开评分方案。

One practical note: the January 2006 question paper is not listed above, so if you are working through the January series in order, use the January 2006 mark scheme as a worked example of method marks and examiner wording rather than as a paper to attempt blind.

一个实用提醒：上面没有列出 2006 年 1 月的试卷。因此如果你打算按顺序做一月场次，可以把 2006 年 1 月的评分方案当作方法分与考官表述的范例来读，而不是当作盲做的卷子。

4. June Session Papers | 六月场次真题下载

The June series is the larger of the two and runs all the way to June 2016, which makes it the most representative set for the later, more refined style of S1 questions. If you only have time for one series, choose June.

六月场次规模更大，一直考到 2016 年 6 月，因此它最能代表 S1 后期更成熟、更精细的出题风格。如果时间有限只能做一个场次，选六月。
