📚 CCEA Pre-U Business Studies: Key Assessment Points for Practical Investigation | CCEA 预科商务：实践调查考核要点

In CCEA Pre-U Business Studies, the practical investigation component requires students to design, carry out and evaluate a small-scale business research project. Success depends not on memorising theory alone, but on demonstrating competence in planning, collecting and interpreting evidence in a real-world context. This guide summarises the key assessment points that examiners look for when marking practical investigations.

在 CCEA 预科商务课程中，实践调查部分要求学生设计、开展并评估一项小规模的商业研究项目。成功不仅取决于死记理论，更取决于在真实情境中展现策划、收集与解读证据的能力。本指南总结考官在批改实践调查时所重点关注的核心考核要点。

1. Research Aim and Hypothesis Formulation | 研究目标与假设构建

Start by stating a clear research aim that explains what the investigation intends to discover. A null hypothesis (H₀) and an alternative hypothesis (H₁) should be set up if statistical testing is planned. The aim and hypotheses must be directly linked to a business problem or issue.

首先要陈述清晰的研究目标，说明调查打算发现什么。如果计划进行统计检验，应设立零假设 (H₀) 与备择假设 (H₁)。研究目标和假设必须与某一商业问题或议题直接关联。

2. Primary and Secondary Research Methods | 一手与二手研究方法

Distinguish between primary data (information collected first-hand, e.g. questionnaires, interviews, observations) and secondary data (information that already exists, e.g. company reports, government statistics, market analysis from Mintel). The best investigations combine both methods, justifying why each source is appropriate for the aim.

区分一手数据（直接收集的信息，例如问卷、访谈、观察）与二手数据（已存在的信息，例如公司报告、政府统计数据、Mintel 的市场分析）。优秀的调查会把两种方法结合起来，并说明每种来源为何适合当前的研究目标。

Primary methods allow bespoke questions but may suffer from small sample sizes.
一手方法可以定制问题，但样本量可能较小。
Secondary methods save time but must be checked for reliability and bias.
二手方法节省时间，但必须查验可靠性与偏差。

3. Sampling Techniques and Sample Size | 抽样技术与样本量

Explain how the sample was selected. Random sampling gives every member of the population an equal chance, while stratified sampling ensures key subgroups are represented. Quota and convenience sampling are easier to carry out but can introduce bias. The sample size must be stated and justified — a larger sample reduces margin of error but may be impractical.

解释样本是如何被选取的。随机抽样让总体中每一成员被抽中的机会相等，分层抽样则确保关键子群得到代表。配额抽样和便利抽样更容易实施，但可能引入偏差。需要陈述样本量并说明理由——样本量越大，误差幅度越小，但可能不切实际。

Technique	Bias risk	Use when
Random	Low	Population list available
Quota	Medium	Time or budget limited
Convenience	High	Pilot or exploratory stage

4. Questionnaire and Interview Design | 问卷与访谈设计

Your research instruments must avoid leading questions, ensure clarity and offer a mix of closed and open questions. Closed questions produce quantitative data that can be easily graphed; open questions generate qualitative insights but are harder to analyse. Always pilot the instrument on a small group first and refine it.

你的研究工具必须避免诱导性问题，确保清晰易懂，并混合使用封闭式与开放式问题。封闭式问题生成易于图解的定量数据；开放式问题产生质性的洞察，但分析起来更困难。一定要先在小范围进行试测，然后修正工具。

In your evaluation, discuss question bias, response rates, and whether the wording could have influenced answers.

在评估部分，应讨论问题偏差、回答率，以及措辞是否可能影响了回答。

5. Data Presentation and Visualisation | 数据呈现与可视化

Raw data must be organised into tables, bar charts, pie charts, line graphs or scatter diagrams as appropriate. CCEA examiners expect clear titles, labelled axes, a key if needed, and a brief comment underneath interpreting what the chart shows. Never present a graph without some written analysis connected to the research aim.

原始数据须整理成表格、条形图、饼图、折线图或散点图，以适应需要。CCEA 考官期望图表有清晰的标题、坐标轴标签、必要时附上图例，并在图下简要说明该图反映了什么。绝不要呈现图表却不附带与调研目标相关的文字分析。

Use measures of central tendency (mean, median, mode) and dispersion (range, interquartile range, standard deviation) where relevant. A scatter graph can be used to suggest correlation between two variables, but remember correlation does not prove causation.

在适当情况下，使用集中趋势量数（平均数、中位数、众数）和离散量数（全距、四分位距、标准差）。散点图可用于提示两个变量之间的相关性，但要记住，相关性不能证明因果关系。

6. Ratio and Financial Analysis | 比率与财务分析

If the investigation focuses on a company’s performance, select appropriate ratios and interpret them in context. Typical categories include profitability (gross profit margin = (gross profit ÷ revenue) × 100%), liquidity (current ratio = current assets ÷ current liabilities) and efficiency (inventory turnover = cost of sales ÷ average inventory). Always compare ratios over time or against industry benchmarks.

如果调查聚焦于某家公司的绩效，请选取合适的比率，并置于具体情境中进行解读。典型的类别包括盈利能力（毛利率 = (毛利润 ÷ 收入) × 100%）、流动性（流动比率 = 流动资产 ÷ 流动负债）和效率（存货周转率 = 销售成本 ÷ 平均存货）。始终要跨时期或对比行业基准来比较比率。

Gross Profit Margin = (Gross Profit ÷ Revenue) × 100%

Current Ratio = Current Assets ÷ Current Liabilities

Do not just calculate — explain the implications. A declining gross profit margin might indicate rising input costs or falling selling prices, both of which need strategic attention.

不要只是计算——要解释其含义。毛利率下降可能表明投入成本上升或售价下跌，两者都需要战略性的关注。

7. Use of ICT in Data Analysis | ICT 在数据分析中的应用

Marks are awarded for effective use of ICT tools such as spreadsheets (Excel formulae, pivot tables, chart wizards), databases and possibly simple statistical functions (e.g. =CORREL for correlation coefficient). Show screenshots or printouts of your spreadsheet models and explain how they helped you analyse the data more accurately or efficiently.

有效使用 ICT 工具可以获得分数，例如电子表格（Excel 公式、数据透视表、图表向导）、数据库，可能还包括简单的统计函数（如用 =CORREL 计算相关系数）。展示电子表格模型的截图或打印件，并解释它们如何帮助你更准确或更高效地分析数据。

Avoid overcomplicating; the tool must serve the research aim, not the other way round. The key is how you used technology to produce meaningful findings.

避免过度复杂；工具必须服务于研究目标，而不应本末倒置。关键在于你如何利用技术得出有意义的研究发现。

8. Identifying Limitations and Evaluating Validity | 识别局限与评估有效性

Every investigation has weaknesses, and acknowledging them shows critical awareness. Discuss sample size, representativeness, potential researcher bias, low response rates, time constraints and any external factors (e.g. seasonal variation) that may have affected results. Distinguish between internal validity (did you measure what you intended?) and external validity (can findings be generalised?).

每项调查都有缺陷，承认缺陷能体现批判意识。讨论样本量、代表性、潜在的研究者偏差、低回收率、时间限制以及任何可能影响结果的外部因素（如季节性波动）。区分内部效度（是否测量了本想测量的东西？）与外部效度（研究结论能否推广？）。

Use your limitations to suggest improvements — this is a high-level skill. For example, if the sample was predominantly young consumers, recommend a future study with a wider age range.

利用局限来提出改进建议——这是一种高阶技能。例如，如果样本以年轻消费者为主，可以建议未来研究扩大年龄范围。

9. Ethical Considerations and Confidentiality | 伦理考量与保密

Business research must follow ethical principles: obtain informed consent from participants, guarantee anonymity, explain how data will be used, and give the right to withdraw. If you studied a real company, respect commercial confidentiality and avoid disclosing sensitive figures without permission. Mention any ethical approval steps taken, even if informal.

商业研究必须遵循伦理原则：获得参与者的知情同意、保证匿名、说明数据用途，并赋予受访者退出的权利。如果你研究了一家真实公司，应尊重商业机密，未经允许不披露敏感数据。即使是非正式流程，也应提及你采取的伦理审批步骤。

Failing to address ethics can lead to loss of marks and undermines the professionalism of the project.

未能处理伦理问题可能导致失分，并有损项目的专业性。

10. Drawing Conclusions and Making Recommendations | 得出结论与提出建议

Conclusions must flow directly from the analysed data and answer the original research question. Do not introduce new information here. Every recommendation should be SMART (Specific, Measurable, Achievable, Relevant, Time-bound) and supported by evidence from the project. Show how the business could implement your suggestions with available resources.

结论必须直接从分析所得的数据中得出，并回答最初的研究问题。此处不要引入新信息。每一条建议都应当符合 SMART 原则（具体的、可衡量的、可实现的、相关的、有时限的），并得到项目证据的支持。展示企业如何利用现有资源落实你的建议。

An evaluation of the likely impact and costs of the recommendations is essential for top marks.

评估建议可能带来的影响与成本，是获取高分的关键。

11. Cross-Referencing and Source Evaluation | 交叉引用与来源评估

All secondary sources must be cited using a consistent referencing system (e.g. Harvard). Evaluate each source for credibility: consider the author’s expertise, publication date, purpose (inform, persuade, sell?) and whether the information is peer-reviewed or sponsored. A bibliography alone is insufficient; you must show critical appraisal of the sources you relied on.

所有二手来源都必须用一致的引用系统（如哈佛体系）进行引用。针对每一来源的可靠性进行评估：考虑作者的专业性、出版日期、目的（告知、说服、推销？）以及该信息是否经过同行评审或赞助。仅有参考文献清单不够；你必须展现对所依赖来源的批判性评价。

12. Structure, Communication and Final Presentation | 结构、沟通与最终呈现

CCEA Pre-U practical investigations are marked on the clarity and logic of the report structure. Use subheadings, consistent formatting, numbered pages and a contents page. The executive summary should capture the aim, method, key findings and main recommendation in no more than half a page. Write in formal, objective language and proofread carefully — spelling and grammar mistakes detract from overall authority.

CCEA 预科实践调查会依据报告结构的清晰度与逻辑性来评分。使用小标题、统一的格式、页码和目录页。执行摘要在半页纸内概括研究目标、方法、关键发现与主要建议。使用正式、客观的语言，并仔细校对——拼写和语法错误会削弱整体说服力。

Your ability to communicate complex business data to a non-specialist audience is a marker of real understanding and is rewarded accordingly.

你能否将复杂的商业数据传达给非专业受众，这体现了真正的理解力，也会相应得分。
