📚 Mastering SQA Psychology Practical Assessments: Key Points for Year 11 | 掌握SQA心理学实践考核：11年级核心要点
The SQA National 5 Psychology course includes a practical assessment called the Assignment, which accounts for a significant portion of your final grade. This component tests your ability to think like a psychologist: planning a study, collecting data, analysing findings, and evaluating the process. Understanding the key assessment criteria is essential for success.
SQA国家5级心理学课程包含一项名为“作业”的实践考核，它占最终成绩相当大的比重。这部分考察你像心理学家一样思考的能力：规划研究、收集数据、分析结果并评价过程。理解关键评估标准对成功至关重要。
1. Understanding the SQA Assignment Structure | 理解SQA作业结构
The assignment requires you to produce a formal research report based on a simple psychological investigation. You will choose a topic, often from the course content, and conduct a small-scale study. The report is marked out of a total mark allocation, with marks given for sections like Introduction, Method, Results, Discussion, and References. You must demonstrate knowledge of research methodology and apply it to your own study.
该作业要求你基于一项简单的心理学调查撰写正式研究报告。你会选择一个主题，通常来自课程内容，并进行小规模研究。报告按满分评定，评分依据引言、方法、结果、讨论和参考文献等部分。你必须展示研究方法知识并将其应用于自己的研究。
Typical word count is around 1,000–1,500 words, but quality matters more than length. The assignment is externally marked by SQA, so adherence to guidelines is critical.
典型字数在1000-1500词左右，但质量比长度更重要。作业由SQA外部评分，因此遵守指南至关重要。
2. Formulating a Clear Research Question and Hypothesis | 提出清晰的研究问题与假设
Your research question should be specific and testable. For example, "Does music affect memory performance?" can be refined into "Does listening to classical music while studying improve recall of word lists compared to silence?" A well-defined question guides your entire study.
你的研究问题应具体且可检验。例如，“音乐影响记忆表现吗？”可细化为“学习时听古典音乐比安静状态下能提高单词表回忆吗？”明确的问题指导整个研究。
From the question, you derive a hypothesis: a precise, testable prediction. There are two main types: experimental (alternative) hypothesis (predicts a difference or relationship) and null hypothesis (states no effect). You may use a directional hypothesis (e.g., "Participants who listen to classical music will recall more words than those in silence") or non-directional if you are unsure of the direction.
根据问题，你推导出假设：一个精确、可检验的预测。主要有两种类型：实验（备择）假设（预测存在差异或关系）和虚无假设（陈述无效应）。你可以使用方向性假设（例如“听古典音乐的参与者比安静状态下能回忆更多单词”）或非方向性假设，如果你不确定方向。
Always include both the experimental and null hypothesis in your report. The null hypothesis is essential for statistical testing. For example, "There will be no significant difference in recall between classical music and silence conditions."
报告中务必同时包含实验假设和虚无假设。虚无假设对统计检验至关重要。例如，“古典音乐与安静条件下的回忆无显著差异”。
3. Variables: Operationalisation and Control | 变量：操作化与控制
hat you measure. In the music-memory example, IV = presence/type of music (levels: classical, silence), DV = number of words correctly recalled. Operationalisation means defining exactly how you will measure or manipulate the variable. For DV, you might say "score on a 20-word recall test." This makes the study replicable.
识别并操作化变量是一项关键技能。自变量（IV）是你操纵的；因变量（DV）是你测量的。在音乐与记忆的例子中，IV = 音乐的有无/类型（水平：古典音乐、安静），DV = 正确回忆的单词数量。操作化指准确定义你将如何测量或操纵变量。对于DV，你可说“20词回忆测试的得分”。这使研究可重复。
Controlled variables (confounding variables) must be kept constant to avoid bias. Examples include time of day, difficulty of word list, instructions given. Failing to control these can undermine the validity of your findings.
控制变量（混淆变量）必须保持不变以避免偏差。例如一天中的时间、单词表难度、给出的指导语。未能控制这些会削弱结果的有效性。
4. Experimental Design Choices | 实验设计选择
You must choose an appropriate design: independent groups, repeated measures, or matched pairs. In independent groups, different participants are used in each condition. This avoids order effects but requires more participants and can be affected by participant variables (individual differences). In repeated measures, the same participants take part in all conditions, reducing participant variables but introducing order effects (practice, fatigue). Counterbalancing can help. Matched pairs tries to match participants on key variables, reducing individual differences, but it is time-consuming.
你必须选择适当的设计：独立组、重复测量或匹配对。在独立组设计中，不同参与者用于不同条件。这避免了顺序效应但需要更多参与者，并可能受参与者变量（个体差异）影响。重复测量中，同一批参与者参加所有条件，减少了参与者变量但引入了顺序效应（练习、疲劳）。可用平衡抵销。匹配对试图在关键变量上匹配参与者，减少个体差异，但耗时。
Explain why you chose a particular design, linking to your study's practicalities and the need to control confounds. SQA expects you to justify your design choice.
解释你为什么选择某种设计，联系研究的实际性和控制混淆的需要。SQA期望你证明设计选择。
5. Sampling and Participants | 抽样与参与者
Describe your sample: target population, sampling method (opportunity, random, stratified, etc.), and sample size. For school-based research, opportunity sampling is common—using available participants like classmates. Discuss strengths and weaknesses of your sampling method. For instance, opportunity sampling is convenient but may lack representativeness, affecting generalisability.
描述你的样本：目标总体、抽样方法（便利抽样、随机抽样、分层抽样等）和样本量。对学校研究而言，便利抽样很常见——使用可得的参与者如同班同学。讨论抽样方法的优点和缺点。例如，便利抽样方便但可能缺乏代表性，影响外推性。
Also state the relevant participant demographics (age, gender, any relevant characteristics) and how you obtained informed consent. Remember to maintain confidentiality—refer to participants as P1, P2, etc.
同样说明相关的参与者人口统计信息（年龄、性别、任何相关特征）以及如何获取知情同意。记住保密——将参与者称为P1、P2等。
6. Ethical Guidelines in Practice | 实践中的伦理指南
All psychological research must follow ethical principles set by the British Psychological Society and SQA. Key issues: informed consent, right to withdraw, deception, debriefing, confidentiality, and protection from harm. You must describe how you addressed each in your study. For example, provide an information sheet, consent form, and ensure participants know they can leave at any time without penalty.
所有心理学研究必须遵守英国心理学会和SQA制定的伦理原则。关键问题：知情同意、退出权利、欺骗、事后说明、保密和免受伤害。你必须描述如何在研究中处理每个问题。例如，提供信息单和同意书，并确保参与者知道他们可以随时退出而不受惩罚。
If your study involved mild deception (e.g., not fully revealing the aim to avoid demand characteristics), you must justify it and explain how you conducted a thorough debriefing afterwards. SQA markers will check that ethical considerations are not just listed but actively applied to your specific study.
如果你的研究涉及轻度欺骗（例如不完全揭示目的以避免需求特征），必须证明其合理性并解释事后如何彻底进行了事后说明。SQA阅卷员会检查伦理考虑不仅是罗列，而是积极应用于你的具体研究。
7. Procedure and Data Collection | 程序与数据收集
Write a clear, step-by-step procedure so that another researcher can replicate your study exactly. Include details like: briefing, random allocation (if applicable), materials used (word lists, music player), the exact instructions given, duration, and how the DV was measured.
写出清晰、逐步的程序，以便另一位研究者能准确重复你的研究。包括细节如：情况说明、随机分配（如适用）、使用材料（单词表、音乐播放器）、给出的确切指导语、持续时间以及如何测量因变量。
Standardisation is crucial. For example, "Participants sat at the same desk, had 2 minutes to study a list of 20 words, then 1 minute to recall them." Mention any pilot testing to refine materials.
标准化至关重要。例如，“参与者坐在同一张桌子前，有2分钟学习20个单词表，然后1分钟回忆。”提及任何改进材料的预试验。
8. Descriptive Statistics and Graphical Display | 描述统计与图示
Analysis starts with descriptive statistics: mean, median, mode, and range. For interval/ratio data, calculate the mean. Then present the results in a table or bar chart. A bar chart should have clearly labelled axes (IV on x-axis, mean DV on y-axis), a title, and appropriate scale. Do not use a line graph unless showing continuous change over time.
分析从描述统计开始：平均数、中位数、众数和全距。对于等距/比率数据，计算平均数。然后以表格或条形图呈现结果。条形图应有明确标注的坐标轴（自变量在x轴，因变量均值在y轴）、标题和合适的刻度。除非显示随时间连续变化，否则不使用线图。
An example table of descriptive statistics might look like:
描述统计表可能类似：
| Condition | Mean recall | SD |
| Classical music | 14.2 | 2.1 |
| Silence | 12.8 | 1.9 |
You do not need to use inferential tests like t-tests at National 5, but you can mention that
