📚 Year 9 AQA Statistics: Report Writing Framework and Model Report | AQA Year 9 统计：报告写作框架与范文
In Year 9 AQA Statistics, you are often asked to write a statistical report based on a given data set or your own investigation. A well-structured report not only demonstrates your ability to calculate measures but also to interpret data, draw conclusions, and evaluate the process. This guide provides a clear framework to help you write effective reports, along with a complete model report on screen time and sleep to illustrate each component.
在 Year 9 AQA 统计学课程中，你经常需要根据给定数据集或自己的调查撰写统计报告。一个结构良好的报告不仅能展示你的计算能力，还能体现你解释数据、得出结论和评价过程的能力。本指南提供了一个清晰的框架来帮助你撰写有效的报告，并附上一篇关于屏幕时间与睡眠的完整范文，以说明每个组成部分。
1. Understanding the Statistical Report | 理解统计报告
A statistical report is a structured piece of writing that presents an investigation from start to finish. It includes a question, a description of data, calculations, graphs, and conclusions. In the AQA Statistics course, your report will be assessed on your ability to handle data, apply statistical techniques, and communicate findings clearly.
统计报告是一篇结构化的文章，从头到尾呈现一项调查。它包括研究问题、数据描述、计算、图表和结论。在 AQA 统计课程中，你的报告将根据你处理数据、应用统计技术以及清晰传达发现的能力进行评估。
Unlike a simple computation exercise, a report requires you to explain what you have found and why it matters. You should always write in full sentences and use appropriate statistical vocabulary.
与简单的计算练习不同，报告要求你解释你发现了什么以及为什么重要。你应该始终使用完整句子和恰当的统计术语来写作。
2. Planning Your Report | 规划报告
Before writing, plan the sections: Introduction, Data Collection, Data Presentation, Analysis, Conclusion, and Evaluation. Decide what your key findings are and what graphs or calculations you need. This plan becomes the skeleton of your report.
在动笔之前，先规划好各部分：引言、数据收集、数据展示、分析、结论和评价。确定你的主要发现是什么，以及你需要哪些图表或计算。这个计划就成为你报告的骨架。
Make sure your report addresses the original question or hypothesis. For example, if the hypothesis is 'Students who spend more time on screens sleep fewer hours,' your entire report should be focused on testing this statement.
确保你的报告回应了最初的问题或假设。例如，如果假设是“花更多时间看屏幕的学生睡眠时间更少”，那么你的整篇报告就应围绕检验这一陈述展开。
3. Writing the Introduction | 撰写引言
The introduction sets the scene. State the aim of the investigation and your hypothesis. Explain why the topic is worth investigating. Keep it concise – one paragraph is enough.
引言部分为报告定下基调。说明调查的目的和你的假设。解释为什么这个主题值得研究。保持简洁——一段就足够了。
Example: 'The aim of this investigation is to explore whether there is a relationship between the daily screen time of Year 9 students and their average hours of sleep. My hypothesis is that higher screen time is associated with less sleep.'
示例：“本调查旨在探究 Year 9 学生每日屏幕时间与平均睡眠小时数之间是否存在关系。我的假设是：更高的屏幕时间与更少的睡眠相关。”
4. Describing Data Collection | 描述数据收集方法
Explain how you obtained the data. Was it a survey, an experiment, or secondary data? Describe the sample: how many people, from which population, and how they were selected. Mention any issues like non-response or bias.
解释你是如何获得数据的。是问卷调查、实验还是二手数据？描述样本：有多少人，来自哪个群体，以及他们是如何选出的。提及任何问题，如无回应或偏差。
For a survey, you might write: 'I distributed a questionnaire to 30 Year 9 students in my school. There were 15 males and 15 females. I asked them to record their screen time (hours per day) and average sleep hours during a school week. I ensured that answers were anonymous to encourage honesty.'
对于问卷调查，你可以写：“我向学校 30 名 Year 9 学生分发了问卷。其中男性 15 人，女性 15 人。我请他们在上学周里记录自己的屏幕时间（每天小时数）和平均睡眠小时数。为确保诚实回答，我采取了匿名方式。”
5. Presenting Data Clearly | 清晰展示数据
Use tables and graphs to organise raw data. Tables should have clear headings and units. Graphs (bar charts, scatter graphs, pie charts) must be labelled, with axes titled and scales appropriate. Always refer to figures in your text.
使用表格和图表来整理原始数据。表格应有清晰的标题和单位。图表（条形图、散点图、饼图）必须带有标注，轴标题和刻度恰当。在正文中总要提及图表。
Table 1 below shows the first few rows of collected data. A full table would list all 30 students. The scatter graph (Figure 1) should be plotted with screen time on the horizontal axis and sleep hours on the vertical axis, each axis clearly labelled with units.
表1下方显示了所收集数据的前几行。完整的表格应列出全部30名学生。散点图（图1）应以屏幕时间为横轴、睡眠小时数为纵轴绘制，每个轴都清晰地标注了单位。
