📚 GCSE CCEA Statistics: Case Study Practical Exercises | GCSE CCEA 统计：案例分析实战演练
Case study questions form a substantial part of the CCEA GCSE Statistics examination. This article walks you through a realistic data investigation, from planning and sampling to analysis and evaluation, applying key statistical techniques required in the specification. By following the steps, you will see how to turn a hypothesis into a fully reasoned conclusion using real data.
案例分析题在 CCEA GCSE 统计学考试中占有重要分量。本文将带领你经历一个真实的数据调查过程，从计划和抽样到分析和评估，运用考试大纲要求的核心统计技术。跟随这些步骤，你将学会如何将假设转化为基于实际数据的完整推论。
1. Introduction to Case Studies in CCEA Statistics | 案例分析方法介绍
In the CCEA Statistics specification, a case study requires you to design, carry out and interpret a statistical enquiry. You must demonstrate understanding of data collection methods, sampling, graphical representation, summary statistics and the evaluation of findings. The practical exercise below models each of these stages with a clear narrative.
在 CCEA 统计学大纲中，案例分析要求你设计、实施并解释一项统计调查。你必须展现出对数据收集方法、抽样、图表表示、汇总统计量以及结果评估的理解。下面的实战演练将以清晰的叙述模式展示每一个阶段。
We will investigate the claim that "students who exercise more hours per week tend to achieve higher scores in their GCSE Mathematics mock exam". This is a typical correlational study, and we will treat exercise hours as the explanatory variable and exam score as the response variable.
我们将检验这样一个说法："每周锻炼时间越多的学生，其 GCSE 数学模拟考试成绩往往越高"。这是一项典型的相关性研究，我们将锻炼小时数视为解释变量，将考试成绩视为响应变量。
2. Case Study Scenario: Student Fitness and Exam Performance | 案例场景：学生体能训练与考试成绩
A group of Year 11 pupils at a large school volunteered to provide data on their weekly exercise hours and their most recent Mathematics mock score (as a percentage). The research question was: 'Is there a positive association between the number of hours spent on physical exercise per week and performance in Mathematics?'
某大型学校的一群 11 年级学生自愿提供了他们每周锻炼小时数和最近一次数学模拟考试百分制成绩的数据。研究问题是："每周体育锻炼时间与数学成绩之间是否存在正相关关系？"
The school's statistics class decided to analyse these data as a formal case study. They began by writing a clear hypothesis and identifying the variables. The aim was not only to find an association but also to practise the full data handling cycle.
该校的统计课班级决定将这些数据作为正式案例分析来研究。他们首先写下了清晰的假设并确定了变量。目的不仅是寻找关联，更在于完整地实践数据处理周期。
