1. Overview of the Statistical Report | 统计报告概述

A statistical report is a formal document that communicates the process and outcomes of a statistical investigation. In Cambridge Year 10 Statistics, you are expected to demonstrate the ability to plan, collect, present, analyse, and interpret data. Your report should tell a coherent story from the initial research question to the final conclusion.

统计报告是一份正式文件，用于传达统计调查的过程和结果。在剑桥 Year 10 统计中，你需要展示计划、收集、呈现、分析和解读数据的能力。你的报告应讲述一个从初始研究问题到最终结论的连贯故事。

2. Title Page & Table of Contents | 封面与目录

The title page should include the report title, your name, candidate number, and the date. Keep the title concise yet descriptive, e.g. “An Investigation into Year 10 Students’ Weekly Screen Time”. A table of contents with page numbers helps readers navigate the report easily.

封面应包括报告标题、你的姓名、考生编号和日期。标题应简洁但具有描述性，例如“关于 Year 10 学生每周电子设备使用时间的调查”。带有页码的目录有助于读者快速浏览报告。

3. Introduction & Research Question | 导言与研究问题

Begin with a clear research question or hypothesis. State why the topic was chosen and what you aim to discover. Provide some background context to set the scene. For example, “This study investigates whether the amount of time Year 10 students spend on social media is linked to their sleep duration.”

以清晰的研究问题或假设开头。说明选择该主题的原因以及你的探究目标。提供一些背景信息以设定场景。例如，“本研究调查 Year 10 学生花在社交媒体上的时间是否与其睡眠时长有关。”

4. Methodology: Data Collection | 方法：数据收集

Describe how data was collected. Mention whether you used a survey, questionnaire, or existing dataset. Explain the sampling method (e.g. random, stratified, or convenience) and the sample size. Always justify your choices and consider practical constraints. Include the data collection sheet in an appendix.

描述数据如何收集。提及你使用了调查、问卷还是现有数据集。解释抽样方法（如随机抽样、分层抽样或便利抽样）和样本量。务必说明你的选择理由并考虑实际限制。将数据收集表放入附录。

---

5. Data Presentation: Tables & Graphs | 数据呈现：表格与图表

Present your raw and processed data in well-labelled tables and graphs. Use frequency tables, bar charts, histograms, pie charts, or scatter diagrams as appropriate. Every chart must have a title, labelled axes, and a key if needed. Avoid clutter and choose graph types that best reveal patterns.

用标记清楚的表格和图表呈现你的原始数据及处理后的数据。适当地使用频数表、条形图、直方图、饼图或散点图。每个图表必须有标题、带标签的坐标轴，必要时添加图例。避免杂乱，选择最能揭示规律的图形类型。

---

6. Statistical Calculations & Analysis | 统计计算与分析

Calculate measures of central tendency (mean, median, mode) and spread (range, interquartile range, standard deviation). Use formulas: mean x̄ = Σx / n, the median position (n+1)/2, and standard deviation s = √[ Σ(x – x̄)² / (n-1) ]. Show your working clearly and interpret what each value reveals about the data.

计算集中趋势（平均数、中位数、众数）和离散程度（极差、四分位距、标准差）的指标。使用公式：平均数 x̄ = Σx / n，中位数位置 (n+1)/2，标准差 s = √[ Σ(x – x̄)² / (n-1) ]。清晰地展示计算过程，并解读每个值所揭示的数据特征。

---

7. Discussion & Interpretation | 讨论与解读

Discuss what the results mean in the context of your research question. Compare different groups using calculated statistics. Identify any outliers and explain their impact. Use phrases like “The data suggests that…” or “This indicates a positive correlation between…” to show analytical thinking.

结合研究问题讨论结果的含义。运用计算出的统计量比较不同组别。找出异常值并解释其影响。使用诸如“数据表明……”或“这表明……呈正相关”等表述，以展示分析性思维。

---

8. Conclusion & Key Findings | 结论与关键发现

Summarise the main findings without introducing new information. Answer your original research question directly. Keep the conclusion concise and supported by the data presented. For instance, “Overall, there is a weak negative correlation between social media time and sleep hours.”

总结主要发现，不引入新信息。直接回答最初的研究问题。结论应简洁，并以呈现的数据为依据。例如，“总体而言，社交媒体使用时间与睡眠时长存在微弱的负相关关系。”

---

9. Limitations & Improvements | 局限性及改进建议

Acknowledge the limitations of your investigation, such as small sample size, biased responses, or measurement errors. Suggest realistic improvements like using a random number generator for sampling or collecting data over a longer period. This demonstrates critical evaluation.

承认调查的局限性，例如样本量小、回答存在偏差或测量误差。提出切实可行的改进建议，譬如使用随机数生成器进行抽样或延长数据收集周期。这体现了批判性评估能力。

---

10. References & Appendix | 参考文献与附录

List any sources of information or data you used, following a consistent citation style. The appendix should include a blank copy of the questionnaire, raw data tables, and any supplementary charts or calculations. Clear labelling keeps the main report tidy.

按照统一引用格式列出你使用过的任何信息来源或数据。附录应包括问卷空白副本、原始数据表以及任何补充图表或计算。清晰的标注能保持主体报告整洁。

11. Model Report Walkthrough | 范文示例贯穿解析

Title: “An Investigation into the Relationship between Hours Spent on Homework and Test Scores among Year 10 Students”

标题：“关于 Year 10 学生作业时间与测验成绩关系的调查”

Research Question: “Is there a positive correlation between the number of hours Year 10 students spend on homework per week and their Mathematics test scores?”

研究问题：“Year 10 学生每周花在家庭作业上的小时数与数学测验成绩之间是否存在正相关？”

Method: “A stratified random sample of 30 students was selected, ensuring equal representation from three ability sets. Each student completed a short questionnaire recording weekly homework hours and their most recent test percentage.”

方法：“采用分层随机抽样选取了 30 名学生，确保三个能力组别比例均等。每名学生完成一份简短问卷，记录每周作业小时数和最近一次测验百分比。”

Data Summary: “The mean homework hours was 6.2, the median was 5.8, and the standard deviation was 2.1 hours. The mean test score was 68%, with a range of 55% to 92%.”

数据摘要：“平均作业时长为 6.2 小时，中位数为 5.8 小时，标准差为 2.1 小时。平均测验得分为 68%，得分范围从 55% 到 92%。”

Graph: “A scatter diagram was plotted with homework hours on the x-axis and test score on the y-axis. A line of best fit showed a moderate upwards trend.”

图表：“绘制了散点图，以作业时长为 x 轴，测验得分为 y 轴。最佳拟合线显示中等程度的上升趋势。”

Conclusion: “The data suggests a moderate positive correlation (correlation coefficient r ≈ 0.62). Students who spent more time on homework tended to achieve higher test scores, but other factors like study efficiency also play a role.”

结论：“数据表明存在中等程度的正相关（相关系数 r ≈ 0.62）。花更多时间在作业上的学生往往测验成绩更高，但学习效率等其他因素也有影响。”
